The Indian startup ecosystem is like the caste system – Quartz

Long before Flipkart and Snapdeal became synonymous with Indian startups and e-commerce, K Vaitheeswaran had co-founded Indias first online e-commerce venture Indiaplaza in 1999. Despite the first-mover advantage, Indiaplaza failed and shut shop in 2013. Now, at a time when the sector is maturing, with firms and their investors looking for profitability, Vaitheeswaran, through his book Failing to Succeed, shares his experiences of starting up. He details his journey and looks at what went wrongsimply put, the company ran out of funding and was forced to shut down. Following is an excerpt from the book.

The Indian startup ecosystem is like the caste system.

The typical profile of an Indian technology entrepreneur is of a young person from a premier technology or management institute in India or abroad and with work experience in an MNC or overseas.

I did not tick any of these boxes. I was almost 50 years old.

I went to a government college in Tirunelveli, a small town in interior Tamil Nadu, and I had never worked for an MNC or in USA. The investors were probably shocked at (a) how I could, with such a poor background and unimpressive profile, co-pioneer an industry and (b) how I still managed to be around for so long without raising billions of dollars.

Asking me to get out of my company was the best way of resuming normal service.

Most investors cannot evaluate a startup with perfect insight at the initial stage; so they resort to the easier option of pedigree investing. If a startup founder matches their typical entrepreneur profile, investors decide to put money in them. Further, most funds also employ associates, senior associates, vice-presidents, and managing directors with similar pedigree and, hence, today you have this nice closed loop where investors and entrepreneurs are all from the same batch of the same institute and before they can recall who won their hostel basketball finals, theres a term sheet on the table.

Pedigree-based investing is not as clever as it sounds. Over 80% of venture capital funds are garnered by start-ups with a pedigree background. Over 90% of all start-ups in India will fail. Therefore, over 72% of all pedigreed start-ups will go down.

In reality, 72% failure rate is terrible. If you were averaging 28% in school, you would still be in school.

Pedigree investing has another drawback. It wrongly assumes that the countrys smartest young people are restricted to students of select engineering and management institutes. I have no doubt that we can find bright young potential entrepreneurs in arts and commerce institutes as well. I have the same complaint against the governments ambitious Startup India programmeall their state centres are only in top engineering colleges. When India is trying to encourage entrepreneurship, we must spread the net much wider.

Germaine de Randamie relieved UFC stripped her title, doesn’t regret turning down Cyborg fight – MMAmania.com

Germain de Randamie was stripped of her Ultimate Fighting Championship (UFC) womens Featherweight title after she refused to face Cris Cyborg at the upcoming UFC 214 event which is slated to go down this weekend (Sat., July 29, 2017) in Anaheim, California -- due to the Brazilians past troubles with performance enhancing drugs (PEDs).

For Iron Lady, staying true to her principles was more important than keeping the title and despite all of the aftermath, she doesnt regret declining the bout. But, she does regret swinging at Holly Holm after the bell rang during their title fight at UFC 208 earlier this year.

I dont regret anything. I stand for my principles and I believe that forbidden substances are not allowed in sport, especially not fighting, she said during a recent interview on The MMA Hour. This is a full contact sport. People have ended up in wheelchairs. I was just reading the other day that a boxer did his first pro fight and is now drinking out of a straw. We put our lives on the line and we are here to entertain people, she said.

I dont regret anything, there are things I dont support and thats my opinion. Of course, I regret that moment in the fight where I threw the combination (after bell rang). I regret it because I play fair and its my deepest apology if I hurt anybody with that, even Holly. Thats not me. I would never risk not winning a world title, being disqualified for something this stupid. Thats not me. But I dont regret any decision I have ever made, she said.

Still, de Randamie is adamant UFC knew of her plans to drop down to bantamweight after her title fight at 145 pounds with Holm, even prior to signing the contract. Thats why she was a bit baffled the promotion decided to strip her when they knew beforehand that she had her eyes on a rematch against Amanda Nunes.

Plus, Cyborgs brief hiccup with USADA -- as well as her hand injury, and full time job as a police officer that requires her to work up to 60 hours a week didnt help the promotions cause in trying to convince Germaine to face Cyborg.

After finding out via social media that she had been stripped, de Randamie says she wasnt too upset. Thats because with the title off her hands, the backlash from fans on social media which included people writing her and advising her to commit suicide came to a halt.

To be honest, it didnt hurt at all. I felt kind of relieved because of all the negative stuff that happened. The negative viral that kept coming and coming and coming. It continued every day. I dont care about the belt, she said.

I do care about is staying me. Its okay that they took away the belt, the only thing I cared about was the things people said. I dont care that people l said Im scared of Cyborg, I fought a guy who was 40 pounds heavier, and in a boxing match. Im not a boxer. I fought the best standup girls in the world, the very, very best. I was the reigning world champion in three different divisions at the same time. I fought every girls, so people can say Im scared because I dont mind as long as I can look at myself in the mirror and know Im not scared. They can say Im a cheater, I am not, it hurts, but its their opinion.

Germaine will return to action against Marion Reneau at the upcoming UFC Fight Night 115 event on UFC Fight Pass, scheduled for Sept. 2, 2017 from inside Ahoy Rotterdam arena in Netherlands. This, despite the fact that Iron Lady requires surgery on her injured hand, which she postponed until after the bout.

As for the 145-pound strap, that will be up for grabs as Cris Cyborg faces Tanya Evinger at UFC 214 in Anaheim, California. For more on that fight click here.

How Civil Rights Wade-Ins Desegregated Southern Beaches – History

65 black and white demonstrators under arrest troop off the beach at Biloxi after staging unsuccessful attempt to desegregate the Gulf Coast beach. Group was led by Dr. Gilbert Mason (center, foreground) and white minister, Rev. R.G. Gallagher, Biloxi (third in line with shorts). The group was arrested for 'trespassing on private property'. (Credit: AP Photo/Jim Bourdier)

The beach in Biloxi, Mississippi is much like any other: palm trees, piers, sparkling water, white sand. But in the 1950s, the beach wasnt open to everyoneuntil a group of African Americans waded into the water to fight against segregation.

On May 14, 1959, Gilbert Mason, Sr., Murray J. Saucier, Jr. and five African American children headed into the Gulf of Mexico. But they werent exactly there to swim. It was the first in a series of three protests designed to desegregate Biloxis beachespublic spaces that were inaccessible to African Americans in Jim Crow Mississippi.

The swimmers were run off the beach by police, who claimed that the beach was off-limits to black people. Negroes dont come to the sand beach, a police officer told the group as he hustled them off the beach. As the men left, says Gilbert Mason, Jr., his father noticed somethinga trashcan labeled Property of Harrison County.

He knew that the countyand taxpayer money paid by black folksmaintained the beach, says Mason, Jr. The beach belonged to the county, not to the individuals that claimed they owned it.

The wade-in, as Gilbert Mason, Sr. later wrote, was no fluke or accident. It was premeditated. It provided a legal test of African Americans right to use the beach their tax dollars helped pay for. First, the men asked to see the law. They were denied and told it was in a locked safe. Then, the county board of supervisors insisted that African Americans were forbidden to use the beachand when Mason, Sr. and a group of friends pressed the board to allow them to use the beach, they were offered a segregated portion instead. Mason, Sr. told the board that he wanted access to every damn inch of it. The mens pleas were dismissed.

Mason, Sr. was familiar with discrimination. He was a physician specializing in family practice, and moved to Biloxi to bring his medical expertise to an underserved area. It took decades for him to receive full privileges at the local hospital, and he could only treat black patients. Daily life in Biloxi was marked by segregation. As historian Neil MacMillan explains for American RadioWorks, Mississippi didnt have many formal segregation laws on the booksbecause it didnt need them. The state was a bastion of anti-black bias, and public spaces were almost entirely segregated, even after the U.S. Supreme Court outlawed school segregation with Brown v. Board of Education in 1954.

Mason, Sr. later wrote, I wanted to live a long life, but I wanted the chance for a full and wholesome life for my family and for us as a people. He decided to fight for his rightsincluding the chance to go to an integrated beach. There were places for black people to swim on the Gulf Coast, including the Gulfside Assembly, a Methodist retreat that also served as a gathering place and training ground for civil rights activists. Black folks would come from all over the South to swim there, says Mason. It was a wonderful, glorious place. But Gulfside was over 40 miles from Biloxi, and African Americans who tried to visit were often attacked.

Mason, Sr. returned to the beach in April 1960 for another wade-in, but no other protestors showed upand he was promptly arrested. Then, on April 24, he went back again. This time, he was accompanied by 125 African Americans. A mob of angry whites was there to meet them. They attacked the protestors with clubs, fists, chains and eventually guns.

Though he wasnt present at the violent wade-inhis parents sent him to Louisiana to stay with familyMason, Jr. remembers the aftermath. Wed get phone calls at our house that would hang up, he recalls. Someone would cut off our power. A dead cat was found on our fence.

Despite being arrested for disturbing the peace, Mason, Sr. staged another protest. On June 23, 1963days after the assassination of civil rights leader Medgar Evers, who was a friend and associate of Mason, Sr.protestors headed back to the beach. This time, they didnt just wade: They planted black flags in the sand in Evers memory. A mob of over 2,000 white rioters gathered during the protest and all 71 protestors were arrested for trespassing.

These were very strategic actions that were planned to get people arrested and beat up so they could bring their cases to court, says David Perkes, an architect and associate professor at Mississippi State University. Perkes leads the Gulf Coast Community Design Studio, which recently was awarded a $100,000 grant for a project that will commemorate the wade-ins and encourage public dialogue about civil rights. Witnessing the Beachthe projects titlewill work with the community to create exhibits and events about the wade-ins, and Perkes studio will create movable platforms that can taken to different wade-in sites for events.

It took until 1968 for the Justice Department to win a lengthy legal battle over Biloxis segregated beachesBiloxis public beaches have been open to all ever since.

The protest really energized people in Mississippi, says Perkes. Though the wade-ins had precedentlike a 1955 wade-in in Floridathey were Mississippis first nonviolent segregation protest.

While today, the wade-ins are hardly remembered, they helped prove an essential pointthat nonviolent protest worked.

Today, a simple historical marker points to the site of the first protesta stretch of sand where people of all races can soak up the sun without fear of reprisal or discrimination.

As ‘Shark Week’ begins, spottings near Maryland, New Jersey beaches – Washington Post

Their names are Mary Lee, Katharine and Hilton. During the summer months, they like to hang out relatively close to beaches along the Mid-Atlantic. They are great swimmers. And they feast on the flesh of gray seals.

Also, they are great white sharks.

Just in time for the Discovery Channels Shark Week, as many Washington-area residents are seeking relief from the heat at beaches in Delaware, Maryland and New Jersey, OCEARCH, a nonprofit group that tracks the movements of sharks, has logged a number of pings from great whites tagged with receivers in their dorsal fins.

Les Kaufman, a Boston University biology professor and shark expert, said that while the number of sharks in the water is believed to be dropping, the kind of technology used by OCEARCH makes it easier for nonscientists to track them, including via an iPhone app.

Scientists know that the sharks are out there, Kaufman said. It becomes news when nonscientists are encountering them ... with advances in the technology theres a greater awareness.

In recent years, OCEARCH has tracked about 300 sharks, including mako and tiger sharks. They tend to swim north in the summer, as the hot weather warms the waters off the East Coast. But while they may sometimes venture near shore, sharks more typically swim miles away from the coastline.

Kaufman said a 13-foot-long shark generally would not swim in water less than three feet deep. In the entire world last year, he noted, only four people died from shark attacks. Many, many more people are killed from complications of insect bites.

Mosquitoes, I mean my god! Kaufman said. Malaria takes a huge chunk of humanity every year, and sharks dont.

OCEARCH followed a 1,300-pound male named Hilton who measures about 12 feet from teeth to tail from the coast of Ocean City on Friday to the Jersey Shore by Sunday.

[12-foot white shark detected near Ocean City]

Other great whites spotted along the East Coast in the last 30 days include Miss Costa, a 1,600-pound, 12-foot female recorded near Nantucket, Mass.; Katharine, a 2,300-pound, 14-footer whose location was noted close to Virginia Beach; and Cisco, a young, eight-foot male who spent Memorial Day weekend in the waters between Lewes, Del., and Cape May, N.J., and just appeared in Nantucket.

Mary Lee, a 16-foot great white, who at 3,450 pounds is about the size of a Toyota Camry, has 125,000 followers on Twitter and was last pinged in mid-June near the Jersey Shore. She spent this past winter near Savannah, Ga., and has traveled as far as Bermuda since she was tagged in September 2012 off Cape Cod.

While great whites in particular are known as fearsome predators, thanks to movies such as Jaws, Kaufman said people should remember that humans have caused much more damage to sharks by overfishing.

We have absolutely raped and devastated the global ocean, Kaufman said.

Still, if you happen to be swimming in the middle of a gray seal colony, like those near Cape Cod, the balance of power could shift, Kaufman said.

Thats a shark cafe, Kaufman said. A high-end shark restaurant.

Vigo County beaches get reprieve for rest of summer – Terre Haute Tribune Star

Beaches at Vigo County parks wont be closing at least for now but their hours will be reduced in a further effort to control vandalism.

Officials last month posted notices warning that Fowler and Hawthorn park beaches would close if thefts, vandalism and other incidents did not stop.

We have seen a slight improvement [but] were still experiencing vandalism, Adam Grossman, assistant superintendent of parks and recreation, told the countys park board Monday.

One very costly deal in recent weeks, Grossman said, involved the cutting of ropes marking safe swimming areas.

Grossman and Kara Kish, parks superintendent, requested, and received, board approval to reduce beach hours to 11 a.m. to 6 p.m. daily through Aug. 8 and cut operations back to weekends only from Aug. 9 through Labor Day, the traditional end of the beach season.

It is within our purview as the managers of the department to make this decision, but seeing as this is something that weve come to you before, we are asking for support, Kish said.

Revised hours are the same as those in place when lifeguards were removed from the beaches a few years ago.

Restrooms have been a frequent target for vandalism. Grossman said reduced hours will allow restrooms to be locked when beaches are not open and for beach attendants to be on hand during operating hours to enforce park rules.

I think its a step in the right direction and we can have discussion in the off season about that, he said.

Sure is a lot better than drawing a line in the sand and saying Youre all gone. I would have hated that, said board member Joe Newton, who last week suggested the 30-day notice of potential closure.

Kish and board members heard a request to sever ties with the National Rifle Association concerning crime prevention and personal safety seminars scheduled for Aug. 4 and Aug. 12 in Clinton.

The NRA has come out, especially in the last few months, with some incredibly extremist propaganda and rhetoric that actually treats our group and its members as the enemy, said Lori Henson of a group called the Activist Study Hall of Vigo County.

Our concern is with the parks department using public resources to arrange, promote (and) sponsor this event with the NRA, Henson said. We also feel there are other groups that are less objectionable that are politically neutral that dont carry the political baggage of the NRA.

Henson presented a letter from her group citing an NRA video that stops just short of calling for armed violence against other Americans for the exercise of their First Amendment rights to free speech and petitioning of government.

The letter calls on the department to withdraw its sponsorship of the upcoming NRA-trademarked Refuse to be a Victim seminar or disinvite the NRA in favor of gun safety and self-defense training by local and state law enforcement and the Indiana Department of Natural Resources

Bear It All Arms Training of Rosedale is scheduled to present the seminar. The business Facebook page says the four-hour course addresses the psychology of the criminal mind; security in the home, workplace, automobiles and travel as well as phone, personal and technology security and self defense tools and training options.

This is not a firearms instruction course and does not include instruction in physical self defense, the page says.

After Henson spoke, parks board President Jeff Fisher said, We appreciate your comments. Thank you.

At the end of the meeting, Kish also thanked Henson for coming and said, We will have discussions about that.

Asked by the Tribune-Star about the request, Kish said only, Well take it under consideration.

Is the Moon’s mantle wet? – Astronomy Magazine

While there are plenty of features dubbed seas on the Moon, none of them ever contained watery depths. For decades, scientists believed this was also true of our satellites interior based on our theories of the Moons formation, its mantle should contain little water. However, a new study indicates that the Moons mantle may be more water-rich than we thought.

The study, published today in Nature Geoscience, was carried out by Ralph Milliken, an associate professor in Brown's Department of Earth, Environmental and Planetary Sciences, and Shuai Li, a recent Brown graduate now working as a postdoctoral researcher at the University of Hawaii. They began seeking a way to more accurately measure the water content of the Moon after studies performed in 2008 and 2011 found traces of water in lunar samples returned to Earth on the Apollo 15 and 17 missions. Based on the amount of water in the samples, which was comparable to the water content of basalts on Earth, planetary scientists calculated that parts of the Moons mantle could contain similar amounts of water much more than previously thought.

But because we have such limited samples of lunar rock from only a few landing sites, it was unknown whether the Apollo mission samples were unique. The key question is whether those Apollo samples represent the bulk conditions of the lunar interior or instead represent unusual or perhaps anomalous water-rich regions within an otherwise dry mantle, said Milliken in a press release.

Thus, the team turned to orbital data taken with the Moon Minerology Mapper, an instrument on the Indian Space Research Organisations Chandrayaan-1 lunar orbiter, to deconstruct reflected sunlight from the Moons surface. Specifically, they looked at large-scale volcanic deposits called pyroclastic deposits, which brought material from deeper within the Moon to its surface. These deposits were not sampled by the Apollo astronauts. By studying the reflected light from these areas, the team aimed to determine the makeup of the material and look for water.

But there was a snag the wavelengths at which water can be detected are also the wavelengths affected by heating as sunlight strikes the Moon. So in order to say with any confidence that water is present, we first need to account for and remove the thermally emitted component, Milliken explained.

That required the pair to understand and model this heating. To accomplish this task, Milliken and Li used the existing Apollo samples in combination with additional data on the heating experienced by the Moons surface to remove this component from the Chandrayaan-1 readings.

Once the heating was removed, the team found evidence for water in almost every volcanic deposit they studied, including sites located near where Apollo 15 and 17 touched down. The distribution of these water-rich deposits is the key thing, Milliken said of their finding. They're spread across the surface, which tells us that the water found in the Apollo samples isn't a one-off. Lunar pyroclastics seem to be universally water-rich, which suggests the same may be true of the mantle.

If that is true, it might require us to tweak our theory of the Moons formation. Previously, the Moon was not thought to contain a significant amount of water because the collision that created it should have been hot enough to destroy the hydrogen required to form water as the debris condensed into our satellite.

However, the new finding does not discredit this theory. The growing evidence for water inside the Moon suggest that water did somehow survive, or that it was brought in shortly after the impact by asteroids or comets before the Moon had completely solidified, said Li. The exact origin of water in the lunar interior is still a big question.

The Great American Solar Eclipse of August 21, 2017 (Part 1) – SYFY WIRE (blog)

[Note: There is a lot to say about this eclipse. Every time I thought I was done writing this, I remembered something else I had to tell you about! Once it hit 3000 words I figured it was better to split it into two parts. Part 1, todays post, is an introduction to the eclipse: why its a big deal, how it works, and where to go see it. Tomorrow, Part 2, will have information on how to safely observe the eclipse what you can do to see it, and just as importantly what you shouldnt do, as well as equipment you might want to have handy. Ill also have extensive links with more information.]

Get ready, America. The Moon is about to eat the Sun.

Yesterday (Sunday, July 23, 2017) was the new Moon, when the Moon is closest to the Sun in the sky. That means we are just one lunation one complete cycle of lunar phases away from what may be the most viewed eclipse in human history.

I say that with some confidence. For one thing, there are more people alive today than ever before, so we have that going for us. Plus, the path of this eclipse cuts right across the continental United States, including some major cities; for millions of people the farthest they need to travel to see it is to their front yard.

And then theres the internet. I expect the live streaming for this event will be one of the biggest data streams weve ever seen. I wonder how many millions of photos will be taken during the roughly two minutes of totality

This eclipse is a big deal.

For one thing, total solar eclipses in any given spot on the Earth are rare. They happen roughly once or twice a year somewhere on Earth, but its a big planet, and a lot of it is hard to reach. 70% is ocean, and a lot of whats left of the real estate is taken up by places like the Arctic and Antarctic. So getting a total solar eclipse over, say, the U.S. doesnt happen often. The last one was in 1979, and that one cut a shallow chord across the northwest.

For another, total solar eclipses are one of the most beautiful, wondrous, awe-inspiring sights nature provides for us. The Moon slowly covers the Sun, taking nearly 90 minutes. In the last seconds before the Sun is totally covered, the sky grows dark, the air cools, birds fooled into thinking night has fallen stop singing and then the moment arrives.

Totality. The last bit of solar surface is blocked by the Moon, and the glory of the corona is revealed.

Ah, the Suns outer atmosphere, the ethereally thin gas that is normally invisible due to the Suns overwhelming glare. But when the Sun is behind the Moon, the corona is visible, sometimes reaching out for several times the Suns diameter. Shaped by magnetic forces, it can appear wispy, or shot through with tendrils, or as just a smooth glow. It all depends on the Suns magnetic mood at that moment.

I know many people who have seen total solar eclipses, and they all say every last one of them that its one of the most beautiful things they have ever seen in their entire lives. For a few moments, under the shadow of the Moon, people gasp, choke up, even weep openly.

Or so I hear. Ive never seen a total solar eclipse. A partial one, sure, many times, but never total. After all these decades of being an astronomer, this will be my first.

So if its your first too, heres some advice on what to do, where to go, and what youll see.

I have some details about how eclipses work below, but first, I devoted an entire episode of Crash Course Astronomy to eclipses (both solar and lunar), and it has most of the basic info you need to understand the whys and hows of this. Its only a few minutes, so watch!

That was a lot in a short amount of time, I know. In the interest of making sure this is understandable, here are some more details.

The Moon orbits the Earth about once per month. As it does so it passes by the Sun once per month as well, usually getting a degree or two away from it in the sky. But every now and again this celestial dance aligns, and the Moon passes directly in front of the Sun. Thats a solar eclipse. The Moon is casting its shadow on the Earth!

One of the most common questions I get asked is, why dont we get a total solar eclipse every four weeks? I explain it in the Crash Course episode, but this video shows it a bit better:

The green square represents the orbit of the Earth. The Sun is in that plane, far to the left. The blue is the plane of the Moon. Looking down, they seem coincident. But when we view from an angle, we see theyre not (like one hula hoop wedged inside another, they intersect at two opposite points, called nodes). The Moons orbit is tilted by about 5 with respect to the Earths, so usually at new Moon (when the Moon is between the Earth and Sun) it passes above or below the Sun in the sky. But a couple of times a year, the Moon happens to be new just as it passes a node, and you get an eclipse.

So what happens during the actual eclipse?

At first you see a little dip (called first contact), a nibble, taken out of the side of the Sun as the leading edge of the Moon moves onto the Suns face. As the Moon progresses in its orbit you see a deeper and deeper cut into the Sun (the Moon appears dead black during an eclipse because its between us and the Sun, so were seeing its unlit side, plus the Sun is so bright it totally overwhelms the far darker Moon). The Sun appears as thick crescent, then a thinner one and then suddenly the Sun is gone, completely blocked by the Moon.

This is second contact, or more commonly: totality.

The time from first to second contact is roughly 70 90 minutes, depending on your location. Totality lasts only minutes, however, because of a cosmic coincidence

The size of an object on the sky depends on two things: How big it is, and how far away it is. The Moon is 3474 kilometers across, and at the time of the eclipse will be about 366,000 km from the Earths center. The Sun is 1,391,000 km across and will be a little over 151 million kilometers from the Earth at the time of the eclipse.

So the Sun is 400 times wider than the Moon, but will be 412 times farther away. These numbers almost exactly balance out, so the Sun and Moon will appear to be the same size in the sky!

Well, almost. The Sun is actually more than 400 times farther away, so it appears fractionally smaller than the Moon. Thats good news for us! If they were exactly the same size, totality would last a fraction of a second. But because the Sun looks smaller, it takes time for the Moon to move across it. For this eclipse, given their sizes and distances, and how fast the Moon moves across the sky (about 1.1 degrees every hour), this all shakes out to totality lasting roughly two minutes.

Ill get back to that in a sec. But once those two minutes or so are up, the Moons trailing edge uncovers the Sun, and boom! Totality is over. Thats called third contact. Then, over the course of the next 70 - 90 minutes the whole thing plays out in reverse. The Sun looks like a thin crescent, then a thicker one and finally the trailing edge of the Moon leaves the Sun altogether. Thats fourth contact, but more importantly, it means the whole thing is done.

But totality is the big show. Thats due to combination of factors. One is environmental: During an eclipse, it gets dark. I mean, duh, but this is really something! It gets dark during the middle of the day, which is weird. This doesnt happen until minutes before totality, actually; even when the Sun is half covered or more you might not notice. But in the minutes leading up things around you start to change.

And once the Sun is totally covered, things change immediately. Thats when the sky gets actually dark, like a deep twilight. You might see stars, and some planets (like Mars and Venus toward the west [to the right in the sky], Mercury very close to the Sun [below and to the left] and Jupiter and Saturn to the east [left] this sky map should help). And of course, the solar corona.

The corona is invisible right up until the last moment before totality. But then it pops into view, far fainter than the Sun but obvious once the Sun is gone. This is what Im looking forward to seeing the most. Ive only seen pictures of it, and itll be very cool to say the least! to see it for myself.

There are tons of details about what to look for during those precious brief minutes of totality. I talk a little bit about them in the Crash Course video (the diamond ring effect, Bailys beads, and more) but the American Astronomical Society has a nice brief synopsis of what to watch out for. Theres enough there to get you started, and a good Google search will fill in the blanks.

So now you know how this works, and what to look for. The next big question is obvious.

In Part 2 of this post Ill go over how to safely observe the eclipse, but to see it at all you need to plan ahead. The Moons shadow on the Earth is relatively small and moves rapidly, so you need to be at the right place at the right time!

This map shows the path of the eclipse. If you go anywhere between the two blue lines, youll see a total eclipse. The red line is the centerline of the path, where the Moon appears to cut most directly across the Sun, and so the closer you are to that line the longer the eclipse will last.

If youre outside the lines, the eclipse wont be total. The farther away from it you are, the less of the Sun will be covered. Youll get a partial eclipse, which is still very cool! But you wont get the glory of totality.

There is an interactive map of the eclipse online (care of NASA and eclipse expert Fred Espenak). You can click on it and itll tell you how much of the Sun is covered from that location, as well as the times of the eclipse events (it might help to check the box labeled Large map on the lower right). Its extremely useful, so check it out! Important: The times listed are in Universal Time, so youll want to make sure you have the right conversion. In August, Pacific time is UT 7 hours, Mountain is UT 6, Central is UT 5, and Eastern UT 4.

Also, heres a video showing the Moons shadow sweeping across the US (note that the local times, duration, latitude and longitude of the shadow center, and the altitude of the Sun over the horizon are shown on the left):

Having said that, heres the bad news: You can bet that pretty much every hotel in the path of totality is booked. You can try to find one, and please do! But I suspect itll be difficult. Many have been booked for a year or more.

Worse, traffic will be very difficult. Because the eclipse happens in the late morning to midday for many locations, a lot of people will get up early and drive to the centerline. A lot of the locations are rural, and not designed to handle thousands of cars all at once. So be prepared: If you get stuck in a traffic jam five kilometers north of the line, youll miss totality! This website has traffic info and has links to real-time traffic data. It should prove useful. Apparently there are still campsites and RVC parks available; check here for more.

Also, be aware of weather. If its cloudy, you wont see it (though itll get completely dark, like nightfall, which is kinda cool). Theres a map online with historic cloud cover of the sky that will show you where the best places are to see it, statistically speaking.

Now, if you dont want to or cannot travel far (or you already live in the eclipse path), you still have options. For one thing, there will be a ton of live feeds streamed online, and Ill have links to some in Part 2.

You can also find out if theres a museum, a planetarium, a university, or an astronomy club near you. I strongly suspect many of them in the country will be holding viewing parties at the time of the eclipse. This has lots of advantages: experts on tap, access to observing equipment (and itll be far more likely to be safe to use, too; see below), live feeds from the centerline, and what will no doubt be a festive atmosphere for the event.

I expect a lot of schools may be holding events as well for the students. If youre a parent, see if theyll allow you to attend maybe even volunteer to help out! They may need help distributing safe viewing glasses, talking to the students, and especially making sure everyone stays safe and views the event in the correct manner so no one damages their eyes.

And that brings me to the next part observing this rare and wonderful astronomical occurrence in a responsible manner that still maximizes the experience.

But thats for tomorrow, in Part 2. Stay tuned!

The Infrared Interferometer, Spectrometer, and Radio Astronomy of the Voyager Spacecraft – All About Circuits

The Voyager spacecraft have been exploring our solar system for the last four decades. As their 40th-anniversary approaches, AAC has been taking a weekly look at the experiments and engineering that made this incredible feat possible.

To honor the upcoming 40th anniversary of the Voyager missions, All About Circuits is exploring the extraordinary engineering that went into developing these spacecraft.

Check out the other articles in this seriesbelow:

This week, series coordinator Mark Hughes will guide you through the infrared, ultraviolet, and radio science experiments the Voyager missions were equipped to conduct.

Photons generated in the photosphere of the sun cover a broad range of energies and wavelengths. The photons leave the sun and travel in all directions until they encounter the atoms and molecules in the atmosphere or on the surface of planets and their moons. Certain wavelengths are reflected, other wavelengths are transmitted, and some wavelengthsare absorbed and re-emitted aslonger wavelengths.

By comparing the intensities of transmitted and reflected light at specific wavelengths through the atmosphere of planets, scientists can determine the composition and relative quantities of atoms and molecules present in the atmosphere and soil. Scientists can also use this information to determine the energy balance of a planet or moon.

By observing the light or radio waves that passthrough the atmosphereof a planet or satellite duringoccultation(when the body of a planet blocks a direct view of the spacecraft), scientists can determine a great deal about the quantity and types of atoms and molecules present in the atmosphere.

Infrared light is electromagnetic energy that is just outside the visible spectrum for humans. The wavelength of the photons is a bit longerand the energies are a bit lower than those of red light. It is useful to scientists because there is a strong correlation between the peak infrared wavelength and the temperature of an object.

The Infrared experiments aboard the Voyager Spacecraft had several stated goals:

According to the Voyager Backgrounder(PDF): "The instrument provides broad spectral coverage, high spectralresolution, and low noise-equivalence-radiance through the use ofdual interferometers. That and the variable resolution of theinstrument, as well as the precision of the radiometer, willallow scientists to acquire information about a wide variety ofscientific questions concerning the atmospheres of the planetsand satellites, local and global energy balance, and the natureof satellite surfaces and the rings." The instrument utilizes two fields of view: the Cassegrain telescope and the solar calibration.

The Deep Space Network antennas that transmit and receive data from the Voyager spacecraft operate at frequencies in the GHz range and are capable of detecting frequency variations that are a fraction of a hertz. As radio waves are transmitted from the Earth to the spacecraft, they are Doppler corrected for the movement of the spacecraft, as well as the movement of Earth. As the radio waves travel through space to reach a spacecraft and are returned back to Earth, they are refracted and perturbed by atoms and molecules in the atmosphere of a planet or moon.

Scientists that study the changes in the radio waves during periods of occultation can use the information to determine the properties of a planet's atmosphere and ionosphere. Particles around the rings of Saturn scatter the radio waves and analysis allows the determination of average particle size distribution and size of the planetary rings.

And, as noted in our other article on the Voyager communications, multiple receiving stations can simultaneously record the transmissions of a spacecraft to accurately determine the spacecraft's trajectory as it travels around and near planets.

The ultravioletspectrometer experiment had four stated goals:

From the Voyager Backgrounder(PDF): "The instrument measures ultraviolet radiation in 1,200-Angstrombandwidth in the range from 400 to 1,800 Angstroms. Ituses a grating spectrometer with a microchannel plate electronmultiplier and a 128-channel anode array. A fixed-position mirrorreflects sunlight into the instrument during occultation.The instrument has a 0.86-degree by 0.6-degree field of view during occultation and a 0.86 by 2-degree field of view for airglowmeasurements.The ultraviolet spectrometer weighs 4.49 kg (9.89 lbs.)anduses 2.5 watts of power."

Electromagnetic energy that passes through the different layers of atmosphere of a planet is affected by the atoms and molecules that are present.By studying the deviations and changes ofoptical and radio energy, scientists can determine the molecular composition, density, and depth of a planet's atmosphere.

Local Astronomy Club preps for Total Solar Eclipse – OurQuadCities

MOLINE, Ill. - The countdown is on until a rare total solar eclipse, and Quad Cities astronomy club is preparing for the once in a lifetime experience.

August 21st will be the first time in 99-years that day will turn to night from coast to coast.

Al Scheidler is president of Popular Astronomy Club in Moline. He says stargazers have been planning to view this eclipse for years.

"They aren't occurring where there are large populations. This time we're lucky enough to have them go right straight through the center of the United States."

A total solar eclipse is when the sun, moon and earth align perfectly with each other, leaving some areas of the united states in the dark for a few minutes during the day.

"Popular Astronomy Club" will be hosting a viewing party at the Moline public library the day of the eclipse.

The group owns a mobile observatory - one of only two in the U.S.

The "path of totality" is the 3000 mile long journey the eclipse will travel, starting in Oregon and ending in South Carolina.

In the Quad Cities, you'll be able to see about 91 percent of total eclipse.

Experts say you should use proper equipment to view the eclipse to avoid permanent eye damage.

Local 4 News chief meteorologist, and eclipse super-fan, Andy McCray, is hoping for clear skies.

"The one thing we can't control though is the weather. We do need clear skies. If it's a cloudy, overcast day it's not going to be nearly as exciting."

If you miss the total eclipse next month, another total solar eclipse will pass through the U.S. in 2024, on a slightly different route.

Staff Reporter,

Raipur,

Professor K P Singh, eminent scientist and X-ray Astronomer from Tata Institute of Fundamental Research Mumbai, explained that like visible radiation generally used for investigation of celestial bodies, X-ray also plays very important role in this work

Professor K P Singh, eminent scientist and X-ray Astronomer from Tata Institute of Fundamental Research (TIFR) Mumbai and Professor Alok Chand Gupta from Aryabhatta Research Institute of Observational Sciences (Nainital) shared their views with students and faculty members of School of Studies in Physics and Astrophysics, Pt Ravishankar Shukla University (PRSU), on Monday, during a one day seminar on Astronomy and Astrophysics. Professor Singh explained that like visible radiation generally used for investigation of celestial bodies, X-ray also plays very important role in this work.

However, X-ray coming from space cannot reach to the Earth, as it is blocked by Earths atmosphere. Hence we need to design a special kind of telescope and install it on a satellite above the atmosphere. Indian astronomers have designed X-telescopes on-board ASTROSAT, this satellite was launched in 2015 by ISRO and now successfully working, he said.

There are many other telescopes and detectors on ASTROSAT. This is Indias first multi-wavelength astronomical mission capable of simultaneous observations in many electromagnetic bands. Hence it has got attention from the astronomers worldwide, he added. He also said that celestial objects like White dwarfs, Neutron stars, and Black holes have very intense gravitational field, hence they accrete matter from the companion.

Falling material can not fall directly to the Black hole, hence it starts spiraling around it and form an accretion disk, this disk gets heated to very high temperatures, which releases huge amount of energy in X-ray band. Hence X-ray telescope are important to study compact objects like White dwarfs, Neutron stars and Black holes, which are otherwise invisible or difficult to see in other electromagnetic radiation.

Professor Gupta from ARIES explained how an active galactic nucleus (AGN) is formed by accretion process on to a super massive black hole. He also discussed in detail about Blazar which is a special class of AGN. Students also interacted with Professor S.K. Pandey, Vice Chancellor of the University and famous Astrophysicist. Other participants includes: Head of Physics Department Professor N Brahme, Faculty members and students from Center for Basic Sciences.

Pt Ravishankar Shukla University Vice Chancellor Professor S K Pandey, who is also an astrophysicist, HoD Dr Namita Brahme and Director Dr N K Chakradhari were present on the occasion.

Discovery of a rare quadruple gravitational lens candidate with Pan-STARRS – Phys.Org

July 25, 2017 Pan-STARRS image of the quadruple gravitational lens candidate. The four images of the quasar are marked A-D. The lensing galaxy is very faint and it was discovered only after careful analysis of the image, its position is marked with an x. Credit: United States Naval Observatory (USNO)

Astronomers from the United States Naval Observatory (USNO) in conjunction with colleagues from the University of California, Davis, and Rutgers University have discovered the first quadruple gravitational lens candidate within data from the Panoramic Survey Telescope and Rapid

Response System (Pan-STARRS) using a combination of all-sky survey data from the USNO Robotic Astrometric Telescope (URAT) and the Wide-field Infrared Survey Explorer (WISE).

USNO graduate student George Nelson, who was performing a URAT variability study of the brightest quasars identified by USNO astronomers using WISE colors, discovered the lens while investigating the optical properties of a bright quasar sample. The paper describing this serendipitous discovery has been accepted for publication in the

Astrophysical Journal. A preprint of the paper may be found at arxiv.org/abs/1705.08359. A paper confirming the discovery by a separate team of astronomers using the Keck Cosmic Web Imager has been submitted to the Astrophysical Journal Letters. A preprint of this paper may be found at arxiv.org/abs/1707.05873.

Since the discovery of the first gravitationally lensed quasar in 1979, gravitational lenses have become powerful probes of astrophysics and cosmology. Because they require a very specific configuration between a background quasar (a bright, distant object powered by a supermassive black hole) and a foreground lensing galaxy, quadruply lensed quasars are especially rare. In fact, to date there are only about three-dozen such objects known over the entire sky.

Gravitational lenses are a manifestation of gravity's ability to bend light, which was predicted by Einstein's general theory of relativity in 1915. Since then many experiments have been carried out to test this theory starting with Sir Arthur Eddington's observations of light bending during a solar eclipse in 1919. When a galaxy acts as a gravitational lens to a background quasar, the lensed quasar appears as dual or quadruple images, depending on the relative location of the lens and the source. Lenses are rare because they require that the galaxy and the quasar be located within a few arcseconds of each other on the sky.

Gravitational lenses are at the forefront of current research in cosmology and astrophysics. In astrophysics, they have been used to uncover the structure of massive galaxies, to study how supermassive black holes relate to their host galaxies, and to gain insight into quasar accretion disks as well as their black hole spin. In cosmology, they have contributed to measuring the distribution of dark matter around galaxies and the expansion history of the universe.

Future radio, X-ray, Hubble Space Telescope and adaptive optics imaging, as well as spectroscopic studies, are already planned to further the study of this lens and to contribute to fundamental research.
