Yellowstone Ecosystem Grizzly Bears Removed From Endangered Species Protection – Newstalkkgvo

On Thursday, U.S. Interior Secretary Ryan Zinke officially removed Yellowstone Ecosystem grizzly bears from the federal Endangered Species Act.

Grizzly Bear recovery Coordinator Hilary Cooley said from her office at the University of Montana that the delisting could have happened back in 2007, but a court challenge left the bears with endangered species protections for another decade. Today, the population has rebounded from as few as 136 bears in 1975 to an estimated 700 today and meets all the criteria for delisting.

We have more data now, and grizzly bears today still meet the recovery criteria, we have adequate regulatory mechanisms in place, and we have been working closely with the states that if they do choose to allow hunting of the bears, those safeguards will be in effect and we have a really good monitoring plan in place, Cooley said. Our job as stewards of the Endangered Species Act is to get the species recovered and then remove them from the list.

Cooley said the Yellowstone ecosystem is approximately three times larger than Yellowstone National Park itself.

It encompasses parts of all three states, she said. Wyoming mostly, but also parts of Montana and Idaho. Those states will individually decide if grizzly bear hunting will take place by sticking to some mortality limits, and thats any human-caused mortality, whether its being hit by a truck or a management removal, or if the states do have a hunt, that mortality limit would apply.

Cooley said the fact that President Donald Trump chose Ryan Zinke to be the Interior Secretary had nothing to do with the delisting announcement on Thursday.

That had nothing to do with it, she said. This has been a long, long process. As I said, we tried to delist in 2007. Along with this listing, its paired with a conservation strategy and we had prepared a draft of that several years ago, so its a multi-year process and you have to start way ahead, so we were going to recommend delisting no matter who was secretary, because they had met their recovery goals.

BitGo is now Working on Security Solutions for the Litecoin Ecosystem – Live Bitcoin News

Things are looking quite good for the Litecoin ecosystem right now. It appears some new developments are on the horizon. That is great news for anyone involved in Litecoin. It will be interesting to see how this will affect the LTC price moving forward. An accelerated rate of development will do wonders for Litecoin, that much is evident.

BitGo, the worlds leading multi-signature technology service provider, now supports Litecoin. For the longest time, BitGo only supported Bitcoin, hence the company name. Now that Litecoin is also supported, things will get very interesting moving forward. BitGo is in the process of providing security services for Litecoin and its related service providers. This is quite good news for anyone involved in Litecoin, to say the least.

Considering how BitGo processes large amounts of Bitcoin transactions, it is expected they will do the same for Litecoin. More specifically, Bitcoin has been able to grow thanks to companies such as BitGO. It is certainly possible Litecoin will move in the same direction. A lot of exchanges rely on their services, and enabling LTC support will certainly help in this regard. A lot of exchanges have Litecoin trading enabled, and secure solutions are always in high demand.

Moreover, there is the recent news of Charlie Lee leaving Coinbase. Lee will now focus on Litecoin development full-time. That is a major development for Litecoin as well, even though it remains to be seen what he is working on. Bitstamp has also finally enabled LTC trading after a very long wait. The company integrated BitGos Litecoin multisig security solution as well. Things are slowly falling into place for the LTC ecosystem, that much is evident.

One thing is certain: a lot of people feel Litecoin could be the dark horse in cryptocurrency right now. More specifically, Bitcoin could see a chain split on August 1st. Ethereum has scaling issues and a clogged up network. Litecoin has the scaling solution most Bitcoin users want in the first place. This will not necessarily warrant an LTC price explosion all of a sudden. Then again, Litecoin is slowly regaining its market position, and things are looking very positive for the future.

Cat Zingano says ‘hell yes’ to fighting winner of Cris Cyborg vs … – Bloody Elbow

She may be out of commission for a bit, but that doesnt mean shes not sharpening her knives. Former bantamweight title challenger Cat Zingano is still recovering from an undisclosed injury. But, despite not having fought since her decision loss to Julianna Pena at UFC 200, she been staying in the gym at Alliance MMA in San Diego and paying close attention to the rest of the division.

After Holly Holms sensational knockout win over Bethe Correia at UFC Singapore last weekend, Zingano had some thoughts about what she wants upon her return. Not only does she want a fight against Holm, but shes more than willing to take on the winner of the upcoming fight between Cristiane Justino vs Megan Anderson at UFC 214, if given the opportunity.

She discussed her intentions with Ariel Helwani over at MMAFighting.

Recently, I was asked about fighting her and for it to be in contention of possibly fighting the winner of Cyborg (Justino) vs. (Megan) Anderson. My answer is hell yes. As soon as my body is ready to safely go back in there, the heads will be rolling once again. The results and trials of the treatments Im focusing on are responding and that makes me happy to hear as an athlete, as well as a normal human. Longevity in health and sport are both my top priorities, as well as in the interest of the UFC, who is providing me huge support at this time.

Again, there are no details as to Zinganos condition or potential recovery time, so theres no way to predict how soon she can be back in action. She remains 9-2 in her professional career. Her UFC record currently stands at 2-2, however, after back to back losses to former champion Ronda Rousey and Julianna Pea. But, given the state of both the featherweight and bantamweight divisions right now, shes likely still in consideration as a top contender for match-ups with the divisional elite.

Shark sightings close some Norfolk beaches – wtvr.com

Please enable Javascript to watch this video

NORFOLK, Va. - Four shark sightings closed down Norfolk beaches Thursday. The Division Head of Aquatics andBeaches said swimming areas were cleared at each beach after sharks came through and stuck around for a little while.

The sharks were spotted at Community Beach, Ocean View Beach and Sarah Constant Beach Park, reported sister station WTKR.

The spotting caused Community Beach to close for about 30 minutes.

Dan Jones, Division Head of Aquatics and Beaches

"I have a family out here and I don't want anything to happen to them. I've seen stories about people getting attacked, so I don't want anything to happen to them," said Angel Lowe, who was at the beach with her kids.

A city official said the shark was reported around 11:30 a.m. and it appeared to be less than six feet long.

Dan Jones, Division Head of Aquatics and Beaches, said four shark sightings in one day is highly unusual, adding they typically wouldn't be this many in one summer. However, he had ideas on why they were coming close.

"There are stingrays, there are flounder, other fish out there that might be a food source for the sharks," said Jones.

A school of dolphins was also in the water at Ocean View Beach along with the sharks.

Saturday, the founder of Ocearch, a nonprofit organization responsible for tagging and tracking sharks including Mary Lee and Katharine, will be at the Aquarium talking about shark science. The event will be at 6:30 p.m. and will be free, but seating is limited to the first 250 guests.

In May three sharks pinged off the coast of Virginia Beach and the Outer Banks.

Two of the sharks were great whites named Mary Lee and Katherine and atiger shark named Weimarpinged nearby around the same time as Katherine.

Five beaches closed due to water contamination – WCVB Boston – WCVB Boston

QUINCY, Mass.

Beaches in Quincy, Braintree, Hull and Marshfield have been closed to swimming after testing showed elevated bacteria levels.

The Patriot Ledger reports the Milton Street section of Wollaston Beach, Darcys and Newport beaches in Hull, Smiths Beach in Braintree and Green Harbor Beach in Marshfield are all over the limit recommended for swimming.

Milton Street was posted Wednesday and the others on Thursday.

Newport Avenue in Hull is four times over the limit and Smiths Beach is double. The other three are under twice the recommended maximum.

In most cases the culprit is rain that washed contamination into the water. The beaches are being retested and results are expected on Friday.

The other 60 salt-water beaches on the South Shore passed bacteria tests this week and are open for swimming.

See water quality test results for each community and for Cape Cod, the South Coast and North Shore.

For more on Quincy beaches, call 617-376-1288, or visit tpl-beaches. For more on Wollaston Beach, call 617-626-4972.

HOW BEACHES ARE TESTED

Sixty-five beaches on the South Shore are tested for intestinal bacteria found in humans and animals.

High levels indicate the possible presence of disease-causing microbes that are present in sewage but are more difficult to detect. Bacterial colonies are filtered from three ounces of water and placed on a gel infused with nutrients and chemicals designed to promote growth.

Left in an incubator, the single cells isolated on the filter grow explosively, forming colonies visible to the naked eye. After one day, the colonies are counted and if they exceed 104 colonies, the beach is closed to swimming.

If the past five samples have a mean exceeding 35 colonies, the beach must also be closed to swimming.

Marylanders don't go to the beach. Instead, they head "down-y ocean," more precisely, to Ocean City, with its 10 miles of free sandy beaches and historic 3-mile-long Boardwalk. Founded on July 4, 1875, when the original Atlantic Hotel opened for business, Ocean City has been attracting vacationers ever since, many of whom return year after year with succeeding generations of their own families. The long wooden boardwalk is Ocean City's iconic gathering place, lined with vintage arcades for games and rides, souvenir shops, and all the deliciously fried food you can eat (for many, a walk on the Boardwalk goes hand-in-hand with a bucket of Thrasher's fries).

Part state park and part national seashore, the 37-mile Assateague Island National Seashore was established in 1962. Assateague (meaning "a marshy place across") is not only visited by more than 2 million people a year who come to enjoy its pristine beaches and unsullied environment but the island is also home to more than 320 species of birds and more than 300 wild ponies.

It’s summer in Seattle: Swim rafts return to Lake Washington beaches – The Seattle Times

You can never predict when summer really starts in Seattle. But here's one exciting measure that hints at fun times on the way.

Sketched June 21, 2017

You can never predict when summer really starts in Seattle. This year, its kicking off with a heat wave. Other years June gloom lasts past the Fourth of July.

Given that unpredictability, Ive started telling people that summer in Seattle starts when the Police DepartmentsHarbor Patrol puts the swim rafts back in place at Lake Washington public beaches. And it ends when they store them away after Labor Day.

Earlier this week, I caught up with part of the crew that takes care of the towing just as they were done tying up one of the rafts at Madison Park Beach. Sgt. Mike Pugel said the summer process is faster because they dont have to spend time securing all the floating platforms together in Andrews Bay, by Seward Park. Seattle Parks Department employee Nathan Wendells said the summer tow is more exciting because the departments lifeguards are eagerto start their duty on the beaches. He said you can expect to see them at work starting this Saturday.

Happy summer, everyone, and remember to swim safely!

Excessive heat persists in deserts; strong rips at beaches – fox5sandiego.com

Please enable Javascript to watch this video

SAN DIEGO -- Extremely hot weather in San Diego County's deserts is expected to persist Friday through early next week and temperatures in other inland areas will spike on Sunday.

A National Weather Service excessive heat warning for the deserts will remain in effect until 9 p.m. Monday. A less severe heat advisory for the valleys and mountains will run from 10 a.m. Sunday until 9 that night.

"Excessive heat will continue through the weekend and through Monday in the lower deserts," according to the NWS. "On Sunday it will become hot across the Inland Empire, the mountains below 5,000 feet, and the inland valleys of San Diego County."

Click here for the latest forecast

Predicted high temperatures Friday are 74 to 79 degrees in inland coastal areas, 77 to 82 degrees in the western valleys, 86 to 91 degrees near the foothills, 90 to 100 degrees in the mountains and around 113 degrees in the deserts, according to the NWS.

High temperatures in the deserts are expected to hover around 115 degrees Saturday, then range from 115 to 120 degrees Sunday and 112 to 118 degrees Monday. On Sunday, highs of 95 to 102 degrees are in the forecast for the valleys and mountains.

The immediate coast was spared from the extreme heat, but those headed to the beaches will have to contend with strong and potentially dangerous rip and longshore currents. A beach hazards statement will remain in effect through Saturday evening.

The hot weather will increase the risk of heat-related illness and anyone working or spending time outdoors would be more susceptible, as will the elderly, children and those unaccustomed to the heat. Forecasters advised residents to reschedule strenuous activities to early morning or evening, drink plenty of water, wear lightweight and loose fitting clothing and be aware of the signs and symptoms of heat exhaustion and heat stroke.

Authorities have also warned against leaving children, seniors or pets in parked cars, which can heat up to lethal levels in just minutes, even with a window partially open.

Tropical Storm Cindy takes toll on area beaches and wildlife – WJHG-TV

PANAMA CITY BEACH, Fla. (WJHG/WECP) - Tropical Storm Cindy blew through the Panhandle causing heavy flooding and wind damage. Local beaches and even some wildlife also took a hit from the storm.

On Thursday things seemed back to normal after Tropical Storm Cindy blew past the coast, but she left her mark on area beaches.

"Erosion is a part of it. Sometimes we'll lose beach and during other times of the year depending on the tides and storms when they hit, sometimes it actually adds to the beach," Brian Addison, manager at St. Andrews State Park said.

Park rangers at Saint Andrews State Park say the storm caused heavy erosion. They say the park's jetties made it worse.

"It creates a swell or an eddy down there so not only do you have the impact from the surge or the swell itself," Addison said, "but it gets in there and it can enhance the erosion."

The park is no stranger to beach renourishment projects. Last winter the Army Corps of Engineers helped restore the beach.

"The fact that they need to put the sand somewhere closest to where they're dredging at so they just put it back in our beach here," Addison said.

The storm also took a toll on the wildlife on the beach. Two out of three sea turtle nests were washed out at St. Andrews. In other areas of Panama City Beach, the storm washed over 9 other sea turtle nests.

"Washed over means that the surf came on to the beach, but our stakes that we mark off are still in tact," Nancy Evou with the St. Andrews Bay Resource Management Association said.

Officials with the St. Andrews Bay Resource Management Association say they're rarely allowed to relocate eggs because of a storm.

"Unless we actually see them exposed and the nest is being washed away then we are allowed to collect the eggs and rebury them," Evou said.

Although Cindy has moved away, rangers say they hope visitors will remain safe near the water. "We're hoping that the water conditions will slowly improve and come down from the double red flags," Addison said.

Representatives with the St. Andrews Bay Resource Management Association say it's important for visitors to not disturb sea turtle nests. They say if people notice any turtles hatching to call the Florida Fish and Wildlife Conservation Commission.

New Hubble find challenges our ideas about galaxies – Astronomy Magazine

Objects in the distant universe appear small and difficult to see unless theyre sitting behind a cosmic magnifying glass. Thats exactly the case for MACS 2129-1, a galaxy lensed by a massive foreground galaxy cluster. Using the Hubble Space Telescope, astronomers have managed to catch a glimpse of this unusual object, which appears to be an old, dead galaxy thats already stopped making new stars just a few billion years after the Big Bang. Not only is this galaxy finished with its star formation earlier than expected, its also shaped like a disk, rather than the fuzzy ball of stars that astronomers assumed theyd see.

The results, which appear in the June 22 issue of Nature, describe a galaxy half the size of the Milky Way, but three times as massive. Its compact disk of old, red stars is spinning rapidly, over two times the speed of the stars orbiting the center of our own galaxy. Astronomers were able to spot it via a phenomenon called gravitational lensing, which occurs when a massive object, such as a galaxy cluster, bends the light from a distant object as it travels to Earth, magnifying the image we see on the sky. This allows researchers to probe very early epochs of the universe that are otherwise unresolvable with todays current instruments.

Based on archival data from the Cluster Lensing And Supernova survey with Hubble (CLASH), the team that discovered the galaxy was able to measure the ages of its stars, its total stellar mass, and its rate of star formation.

What they found was puzzling.

In our current picture of galaxy formation, disk-shaped galaxies (like our own Milky Way) in the early universe make stars throughout their youth, appearing blue with bright, young stars before evolving into red and dead elliptical galaxies in our local universe. This transition is largely thought to occur through mergers, which randomize the orbits of the stars in the resulting galaxy, transforming it from an ordered disk into an elliptical shape. Thus, older, more massive galaxies should be elliptical balls of stars, not coherent disks.

So as a disk galaxy in the early universe thats evolved past its star-forming phase into the dead phase without mergers, MACS 2129-1 challenges that picture. This new insight may force us to rethink the whole cosmological context of how galaxies burn out early on and evolve into local elliptical-shaped galaxies, said lead researcher Sune Toft of the Dark Cosmology Center at the Niels Bohr Institute, University of Copenhagen, in a press release.

What could have caused this galaxy to burn out so early while retaining its disk shape? The exact cause is unknown, but some of the most likely possibilities include an active central supermassive black hole or streams of cold gas flowing into the galaxy, either of which could prevent new stars from being born.

For now, MACS 2129-1 is the only galaxy of its kind that doesnt fit the mold. But that could arise from the fact that astronomers have long assumed that distant dead galaxies look like their local universe counterparts. Because these distant galaxies are hard to see without serendipitous events like the lensing phenomenon that brought MACS 2129-1 to astronomers attention, those assumptions could be incorrect.

Perhaps we have been blind to the fact that early dead galaxies could in fact be disks, simply because we haven't been able to resolve them, said Toft.

Tofts team hopes that with the launch of the James Webb Space Telescope, theyll gain a more powerful tool to see such faraway, hard-to-resolve objects without relying solely on lensing. A larger sample of galaxies like MACS 2129-1 would tell astronomers whether their ideas about galaxy formation and evolution need updating, as well as provide clues as to the reason these galaxies have stopped forming stars so abruptly.

This brown dwarf used to be inside its white dwarf companion. – Astronomy Magazine

About 2,700 light years away from Earth, an incredibly rare event is occurring: a white dwarf and brown dwarf are closely orbiting each other in less than an hour and a half.

The white dwarf, which scientists are calling WD 1202-024, was discovered in 2006. WD 1202 became a white dwarf about 50 million years ago when it ran out of usable hydrogen in its core. When a study showed WD 1202 having a consistent change in brightness, astronomers assumed the white dwarf was a variable star. While studying what caused the change in brightness, astronomers were surprised to find that its actually caused by a companion brown dwarf.

The pair is only separated by about 192,625 miles (310,000 kilometers), which is closer than the Moon is to Earth. The white dwarfs gravity is so strong and so fast 62 miles (100 kilometers) per second that it pulls the brown dwarf into an orbit that is completed every 71 minutes.

The brown dwarf, like all brown dwarfs, is too big to be considered a planet, but not big enough to sustain nuclear fusion. This brown dwarf is 67 times the mass of Jupiter and about the equivalent diameter. Because white dwarfs are small husks of former stars, its also wider (though not as massive) as its home dead star. Since its so much bigger than the white dwarf it blocks the light from us when it passes by it.

WD 1202 burns at a scorching 40,352 Fahrenheit (22,000 Celsius), making it bright enough to see, while the brown dwarf is too faint to be seen without the help of its white dwarf companion.

Astronomers believe the brown dwarf was inside WD1202 about 50 million years ago when WD 1202 expanded to become a red giant, becoming bigger than the brown dwarfs orbital distance and engulfing the entire brown dwarf. But the brown dwarf survived when the density of the gas in the red giants outer layers dropped while it expanded, saving the brown dwarf from becoming so hot that it shrunk its orbit.

The brown dwarf is orbiting so closely to WD 1202 that its slowly getting drawn into its host star. Astronomers believe in about 250 million years the brown dwarf will get so close that the white dwarfs gravity will draw material from the brown dwarf and eventually end up a type 1a supernova when theres enough material mixed with intense gravity and the white dwarf will go through sudden catastrophic fusion and explode with a flare in brightness over the system, before cooling and dimming again, to repeat all over again in years to come.

Jerry Nelson, astronomer who built advanced telescopes, dies – Paradise Post

SANTA CRUZ, Calif. (AP) Jerry Nelson, an astronomer who designed advanced telescopes that help scientists glimpse far reaches of the universe, has died in California. He was 73.

The University of California, Santa Cruz, where Nelson was a professor emeritus of astronomy and astrophysics, said he died June 10 at his home. No cause was given.

Nelson's design using dozens of segmented mirrors rather than a single large one was the basis for the Keck Observatory's twin 10-meter telescopes on Mauna Kea, a dormant volcano in Hawaii. Those telescopes, among the largest in use, have allowed scientists to measure the black hole at the center of the Milky Way and to spot planetary bodies outside our solar system.

"Jerry's impacts on the field of astronomy and astrophysics are legendary, and we will all benefit from his legacy for many years to come," said Claire Max, director of UC Observatories.

Nelson's concept has since been used for other large ground-based telescopes around the world. The space-based James Webb telescope, which is under construction, also has a segmented primary mirror design.

Nelson also played an important role in the development of adaptive optics technology, which sharpens the images from ground-based telescopes by correcting for the blurring effect of Earth's atmosphere, the university said.

Even after a stroke in 2011 that left him partly disabled, Nelson continued work for the Thirty Meter Telescope, a project to build the largest telescope in the Northern Hemisphere.

"His endless curiosity always pushed the scientists around him to think more deeply, and his persistence and continued excellence after his stroke were inspirational to everyone," said Michael Bolte, a professor of astronomy and astrophysics at UC Santa Cruz.

Born near Los Angeles, Nelson earned an undergraduate degree from the California Institute of Technology and a Ph.D. in physics at UC Berkeley, where he taught for years before moving to Santa Cruz. He also worked for more than a decade at Lawrence Berkeley National Laboratory.

Nelson is survived by his wife, sister, two children from his first marriage and three grandchildren. His first wife died in 1992.

Bradford library to offer astronomy workshop – Piqua Daily Call

BRADFORD Glancing at the Stars, a workshop presented by the amateur father-son duo of Paul and Eric Sullenberger from Piqua, will be held at the Bradford Public Library on Thursday, June 29. In case of inclement weather, the workshop will be rescheduled for Tuesday, July 18.

Eric Sullenberger, teacher at Russia Schools is an avid astronomer as is his father, Paul. Their program will begin at 8 p.m. in the Community Room, then proceed to the Y-Yard, across from the library to view the heavens.

Due to the tilt of the earth, you may see Jupiter and Saturn, the four Galilean moons of Jupiter, as well as Saturns rings. In addition, the bright stars Regulus in the constellation of Leo, Antares in Scorpius, Spica in Virgo and Arcturus are all good targets.

The beginning of the program will discuss the upcoming solar eclipse on Aug. 21, and include examples of solar viewing glass filters and other methods for safe viewing. The workshop also will give a thorough view of what astronomy is and what is included in the science of astrology, such as Naked-Eye Astronomy, the use of magnified viewing, other tools and computer applications, taking a look at our own galaxy, what lies beyond and what is now termed The Great American Eclipse.

Bradford Public Library would like to know how many people will be attending, so please call (937) 448-2612 to sign up.

NASA begins independent review of WFIRST mission – SpaceNews

WFIRST was the No. 1 rated large-scale mission in the 2010 decadal survey for astrophysics. Credit: NASA illustration

WASHINGTON NASA announced June 22 the selection of an independent review committee that will examine cost and schedule issues with its next flagship astronomy mission, the Wide Field Infrared Survey Telescope (WFIRST).

NASA said earlier this year it would establish the review committee, a recommendation of a study last year by a National Academies panel examining the progress made on implementing the 2010 astrophysics decadal survey. That panel was concerned about growing cost estimates for WFIRST and its implications for other NASA astrophysics programs.

The committee is co-chaired by Peter Michelson, the chair of the physics department at Stanford University who has worked on high-energy astrophysics missions such as Fermi; and Orlando Figueroa, a retired NASA official whose career included serving as deputy director of the Goddard Space Flight Center and director of NASAs Mars exploration program. The other members include a mix of scientists, engineers and program managers.

We are confident this review will provide the insight and confidence among key stakeholders necessary to move toward what promises to be an exciting science investigation bound to reshape our understanding of the universe, Thomas Zurbuchen, NASA associate administrator for science, said in a statement announcing the membership of the review panel.

WFIRST, the top-ranked large, or flagship, mission in the 2010 decadal, is still in its early phases of development. The mission was scheduled to enter Phase B in October, but agency officials previously said they would delay that until the completion of the independent review and implementation of any recommendations from that report.

We have paused the progress towards the systems requirements review for WFIRST, Paul Hertz, director of NASAs astrophysics division, said in a presentation June 22 to the Astronomy and Astrophysics Advisory Committee. That independent review committee has already started its work, he said, including meetings with the project.

Hertz said he expected a final report from the panel in the fall. Once we have a report in hand, then NASA will incorporate the reports recommendations into our planning, possibly even impacting our design for WFIRST but certainly our plans for WFIRST, he said. That will delay the project by several months, he added.

WFIRST, an infrared telescope that will use a 2.4-meter mirror assembly provided to NASA by the National Reconnaissance Office in 2012, is currently scheduled for launch in the mid-2020s. Hertz said that schedule will depend in large part on funding the mission receives.

The earlier we can make money available, the faster they go and the earlier they launch, he said. Unfortunately, unless my budget goes up, we cant accelerate WFIRST and maintain a balanced program at the same time, so we will not be accelerating WFIRST unless we get additional funds.

Finding that balance is already a struggle for NASAs astrophysics program. NASA requested $90 million for WFIRST in its fiscal year 2017 budget request, but the final appropriations bill passed by Congress in early May provides $105 million for the mission. Hubble and SOFIA also received slight increases, as did a mirror technology program not in the agencys request.

However, the overall astrophysics program received $31 million less than the original request. Taking into account those increases specified for WFIRST and other programs, the rest of the astrophysics division is facing a cut of $47.4 million, or about 11 percent.

Hertz said NASA has submitted an operating plan to Congress that addresses those cuts, but since the plan has yet to be approved he could not discuss its details. Complicating matters, he said, is the fact there is now only a little more than three months left in the fiscal year to incorporate those changes.

The places where we would like to accommodate this reduction we have slowed down our spending on, so that if Congress approves our operating plan, we can actually execute the operating plan we submitted, he said. If they tell us that its unacceptable to slow down on the things that we identified, and they tell us to slow down on something else, then its going to be challenging.

Santa Cruz astronomer Jerry Nelson dies – KSBW The Central Coast

SANTA CRUZ, Calif.

Jerry Nelson, an astronomer who designed advanced telescopes that help scientists glimpse far reaches of the universe, died in his Santa Cruz home. He was 73.

The University of California, Santa Cruz, where Nelson was a professor emeritus of astronomy and astrophysics, said he died June 10. No cause of death was given.

Nelson's design using dozens of segmented mirrors rather than a single large one was the basis for the Keck Observatory's twin 10-meter telescopes on Mauna Kea, a dormant volcano in Hawaii. Those telescopes, among the largest in use, have allowed scientists to measure the black hole at the center of the Milky Way and to spot planetary bodies outside our solar system.

"Jerry's impacts on the field of astronomy and astrophysics are legendary, and we will all benefit from his legacy for many years to come," said Claire Max, director of UC Observatories.

Nelson's concept has since been used for other large ground-based telescopes around the world. The space-based James Webb telescope, which is under construction, also has a segmented primary mirror design.

Nelson also played an important role in the development of adaptive optics technology, which sharpens the images from ground-based telescopes by correcting for the blurring effect of Earth's atmosphere, the university said.

Even after a stroke in 2011 that left him partly disabled, Nelson continued work for the Thirty Meter Telescope, a project to build the largest telescope in the Northern Hemisphere.

"His endless curiosity always pushed the scientists around him to think more deeply, and his persistence and continued excellence after his stroke were inspirational to everyone," said Michael Bolte, a professor of astronomy and astrophysics at UC Santa Cruz.

Born near Los Angeles, Nelson earned an undergraduate degree from the California Institute of Technology and a Ph.D. in physics at UC Berkeley, where he taught for years before moving to Santa Cruz. He also worked for more than a decade at Lawrence Berkeley National Laboratory.

Nelson is survived by his wife, sister, two children and three grandchildren. His first wife died in 1992.

UC Santa Cruz issued the following press release:

"Jerry Nelson, a pioneering astronomer known for his innovative designs for advanced telescopes, died June 10.

A professor emeritus of astronomy and astrophysics at UC Santa Cruz, Nelson was project scientist for the Thirty Meter Telescope (TMT) and had served as project scientist for the W. M. Keck Observatory in Hawaii from 1985 through 2012.

Nelson conceived the revolutionary segmented mirror design of the Keck Observatory's twin 10-meter telescopes, and he developed new techniques to fabricate and control the mirror segments. Each telescope has an array of 36 hexagonal segments, precisely aligned to act as a single reflective surface. This design has since been used for other large ground-based telescopes, and the next-generation James Webb Space Telescope also has a segmented primary mirror design.

Nelson also played an important role in the development of adaptive optics technology, which sharpens the images from ground-based telescopes by correcting for the blurring effect of Earth's atmosphere.

As founding director of the Center for Adaptive Optics, a National Science Foundation Science and Technology Center based at UC Santa Cruz, Nelson helped pioneer the use of adaptive optics in astronomy.

Claire Max, director of UC Observatories and the Bachman Professor of Astronomy and Astrophysics at UCSC, said Nelson was a renowned figure in the international astronomy community. "Jerry's impacts on the field of astronomy and astrophysics are legendary, and we will all benefit from his legacy for many years to come. He was a wonderful colleague and mentor to many of us," she said.

Much of Nelson's early research was in the area of high-energy physics and astrophysics. He analyzed the results of particle accelerator experiments and studied high-energy astrophysical phenomena such as pulsars using innovative astronomical instruments of his own design.

Nelson presented the concepts that led to segmented-mirror telescopes in a series of papers and technical reports starting in 1977, often working with UC colleagues Terry Mast and Gary Chanan. The largest telescopes at that time had been fashioned by polishing a single glass "blank" to the requisite precision of a small fraction of the wavelength of visible light. In order to maintain that surface, the polished mirrors had to be very thick and were therefore heavy, which was a problem for larger mirrors. Nelson's idea was to create a single, high-precision optical surface by supporting individual hexagonal mirrors in a close-packed honeycomb configuration. Making this concept a reality required a series of innovative ideas for fabrication, measurement, and control of the mirror segments.

Nearly twice the diameter and four times the light-gathering capacity of the previous largest ground-based telescopes, the twin Keck Telescopes had an enormous impact on astronomy and astrophysics research.

"The segmented-mirror design will be seen as one of the major turning points in telescope technology and one that opened the path to much larger telescopes on the ground and in space in the coming decades," said Michael Bolte, a professor of astronomy and astrophysics at UC Santa Cruz. Bolte, who serves on the TMT Board of Directors, said the TMT's 30-meter primary mirror design is essentially a scaled up version of the Keck primary mirrors.

After suffering a stroke in 2011, Nelson coped with significant physical limitations but remained deeply engaged in TMT design work. "He was a wonderful colleague. His endless curiosity always pushed the scientists around him to think more deeply, and his persistence and continued excellence after his stroke were inspirational to everyone," Bolte said.

A symposium to honor Nelson was already planned for July 13 and 14 in Santa Cruz, featuring talks by many of the eminent astronomers who worked with him over the years. The gathering will now serve as a memorial celebration of his life, Bolte said."
