Recreate The Hubble Space Telescope Missions In VR With Shuttle Commander – UploadVR

Posted: November 17, 2019 at 2:32 pm

A new VR title, Shuttle Commander, will let you recreate the Hubble Telescope Missions. Shuttle Commander is planned for all major VR platforms in 2019 but currently does not have a specific release date.

The experience will offer accurate recreations of the space missions, the shuttle cockpit and Hubble Space Telescope and allow you to play through various different aspects of the Hubble missions. Youll be able to play as a member of the Shuttle crew, take part in deployment, upgrade and servicing of the telescope and land the Shuttle back on Earth. There will even be scoreboards and achievements for shuttle landings.

Shuttle Commander is developed by Immersive VR Education the creators behind a series of educational VR projects including Apollo 11 and the new project also allows you to experience the discoveries of the Hubble Telescope and how it changed our understanding of the universe around us. According to the description on their YouTube video, Shuttle Commander will be available on all major VR platforms this year and trailer itself also features the Oculus, Vive, SteamVR logo and PlayStation logos.

Will you be launching off into space when Shuttle Commander lifts off later this year?Let us know in the comments below.

Right from taking images of aeging to dying stars, Hubble Space Telescope has given us a visual treat of the Outerspace. Hubble Space Telescope belongs to the National Aeronautics and Space Administration (NASA) and the European Space Agency (ESA). News Nation brings to you the five breathtaking images of our universe captured by Hubble Telescope.

Hubble Space Telescope captured two galaxies of equal size in a collision that appears to resemble a ghostly face. Hubble described the two galaxies of equal size as "The Red Spider Nebula might look like a cosmic arachnid, but it's actually the cast-off outer layers of a dying Sun-like star. The hot star's powerful stellar winds create waves in the expelled gas.

Spooky face spotted in space by Hubble Telescope – FOX 31 Denver

Posted: November 6, 2019 at 12:42 pm

CAPE CANAVERAL, Fla. Although it looks a bit like an eerie, floating face suspended in space, the optical illusion spotted by theHubble Space Telescopeis really the result of two galaxies colliding.

Hubble took the image in June as part of its snapshot program, using gaps in its observation schedule to take photos of other intriguing targets.

The two glowing eyes of the face each represent the center of a galaxy.

Young blue stars help make up the outline of the face, while other groupings of new stars seem to sketch out a mouth and nose.

Galaxies arent the kindest of neighbors. They can crash into each other or one can cannibalize parts of another that comes too close.

But this system was formed by a relatively rare, head-on collision.

That means the ring we see that makes up the face is ephemeral, only lasting about 100 million years a short time on the universal time scale.

The ring formed when each galaxys disk, which is filled with gas, dust and stars, was pulled and stretched out by the collision.

This is the Arp-Madore 2026-424 system 704 million light-years from Earth, as noted in the Catalogue of Southern Peculiar Galaxies and Associations.

The Arp-Madore catalog is the result of work published by astronomers Halton Arp and Barry Madore, who both searched for unique galactic interactions.

Their combined work detailing thousands of galaxies was released in 1987.

Rings are rare because there are only a few hundred of them known in our corner of the universe. The circumstances that create them have to happen in a certain way for the ring to form.

And because the galactic centers of each one seen in the image appear to be the same size, that means the galaxies were equal in proportion before they collided. Usually, larger galaxies cannibalize smaller galaxies.

Hubbles growing collection of images, those of including unusually interacting galaxies, can provide astronomers with information about how galaxies evolve.

Hubblesobservationscan also help determine targets for future space telescopes, like the James Webb Space Telescope launching in 2021.

Can blind auditions help women succeed? Yes. – BusinessWorld Online

Posted: at 12:42 pm

By Faye Flam

ITS BECOME a kind of sport to shoot down social science claims, whether its the notion that you can ace interviews if you stand like Wonder Woman or charm your next date by reading two pages of Moby Dick before you leave.

And now critics have taken aim at a prize target a much-cited claim that symphony orchestras hire more women when they audition musicians behind a screen. There are big implications here, since the study has been used in diversity efforts across industries, which is why the take-down has taken off in the media.

But the blind auditions wont go the way of the other results that have vanished into air upon a more critical analysis. One reason is that blind auditions really exist; they were not a contrivance set up by scientists in a lab, as with the studies that have become infamous in the so-called replication crisis. Those mostly relied on experiments from which researchers made oversized and often counterintuitive claims. Some, it turned out, incorporated errors in statistical analysis that made random noise look like surprising new findings.

In contrast, blind auditions were independently adopted by real orchestras, starting with the Boston Symphony Orchestra, in the latter part of the 20th century. The purpose was to prevent conductors from choosing their own students, or their personal favorites, and instead force them to focus entirely on the music. Its also been adopted for awarding astronomers time on the Hubble Space Telescope a limited resource that has only gone to a small fraction of astronomers who submit proposals.

In the 1990s, two economists Claudia Goldin, an Economics professor at Harvard, and Cecilia Rouse, now an economics professor at Princeton University set out to investigate whether blind selection in orchestras was the direct cause of a concurrent increase in the number of women hired for orchestra positions.

Goldin and Rouse went around the country to different orchestras to observe their auditioning practices and collect data on past practices as well as records of who auditioned and who got hired. Much of that data was buried in files in basements. They learned interesting things on the journey including the fact that some orchestras used carpeting or other measures to disguise the difference in sound between male and female footsteps.

The results, published in 2000, were complicated. There are different rounds of selection preliminary, semi-finals, and finals, and women did better in blind selections in some rounds but not others. This was reflected in the abstract of their paper, which admits up front that their data are noisy and some of their numbers dont pass standard tests of statistical significance.

In an interview, Goldin said that they were particularly interested in seeing what happened to the subset of people who applied to both blind and non-blind auditions. Asking people to audition behind a screen might bring in a different, more diverse group of applicants, she said, but there were some musicians who applied to both kinds. Comparing how they performed in blind versus non-blind auditions would offer a kind of natural experiment. And thats where those controversial numbers surface.

The paper says that, using the audition data, we find that the screen increases by 50% the probability that a woman will be advanced from certain preliminary rounds and increases by severalfold the likelihood that a woman will be selected in the final round. The results were cited by politicians and TED talk speakers, and often referenced by other researchers.

One of the critiques came from Columbia University statistics professor Andrew Gelman, whose blog posts have become known for identifying and explaining the kinds of statistical errors or cheats that have led to erroneous or misleading conclusions in social science and medical research.

He criticized the lack of clarity in the paper, writing that he could not figure out how they calculated the much-touted 50% figure, let alone the several-fold difference mentioned, so it was impossible for him to see whether these numbers stand up to statistical tests.

Thats a fair criticism. But even if their data were too noisy to determine that blind auditions increased female hires, that doesnt prove that theres no effect, or that discrimination didnt exist. Goldin said that their number comes from isolating just the cases where the same people applied in both kinds of auditions, and applies, as the paper says, only to certain stages in the process.

A similar study of the Hubble Telescope time got a comparable result. When identifying information was removed from proposals, women became more likely than men to get approved for the first time in the 18 years the data were tracked. As described in detail in Physics Today, the blinding also resulted in more time going to researchers from lesser-known institutions. Reviewers had to look at the substance of the proposals in more depth rather than relying on the track record of the proposers.

A third study looked at coders and found that in gender-blind submissions, womens code was more likely to be accepted than mens; but when the coders gender was known, womens code was accepted less often.

We shouldnt lump a study that examined decades of hiring data at real orchestras in with the headlines that oversold findings that forced smiles make you happier, that hearing words associated with aging make you walk more slowly, and that women are much more likely to vote for Republicans at certain points in the menstrual cycle.

Unlike those other disappearing findings which blustered about a whole new understanding of human nature or offered people too-easy-to-be-true life hacks this blind audition paper was modest, claiming only to shed light on a cultural phenomenon at a particular place and time. Theres no reason to throw it into the trash heap of bad science.

The Camera That Will Transform Our Understanding of the Universe – Atlas Obscura

Posted: August 22, 2017 at 11:41 pm

The LSST is getting close to completion. LSST Project/NSF/AURA

Theres a mystery at the heart of physics. Two decades ago, in 1998, cosmologists discovered that the universe is not just expandinga discovery of the early 20th centurybut that the rate at which its expanding is getting faster.

Thats not what they expected to find, but it made a kind of sense. If the expansion of the universe is accelerating, there needs to be a cause; not knowing exactly what that was, physicists called it dark energy. In theory, dark energy interacts through gravity, is spread out homogeneously through the universe, and is not particularly dense. If you total up all of the forces that make up the universe, it would account for 68.3 percent of matter and energy.

Account for dark energy, and certain theories of physics start to click. It helps explain the rate that galaxies rotate and reveals a more sensible age of the universewithout dark energy, scientists were finding that some stars were supposedly older than the universe as a whole. But almost 20 years after this discovery, physicists still know only a little bit about it. In order to learn more, scientists from dozens of institutions in 23 countries have been working together to create the Large Synoptic Survey Telescope, a giant, digital camera that has the power to capture the light of several billion faint galaxies, millions of light years away.

All the existing telescopes with cameras were built before the discovery of dark energy, said Paul OConnor, a senior scientist at Brookhaven National Laboratory. We expect the LSST to map the entire sky and find out where all that dark matter has been hiding. OConnor has been working on the projects camera sensors for more than ten years, and at Atlas Obscuras Total Eclipse festival on Sunday, he explained how the telescope, when it goes into operation on a mountain in Chile, could transform our fundamental understanding of the universe.

For millennia, scientists and scholars have been looking at the night sky and recording their impressions with the best technology available. Starting in the 18th century, with the advent of photography, astronomers started taking pictures of the stars and other celestial phenomena; in 1851, a daguerreotypist, Johann Julius Berkowski, took the first photo of a solar eclipse. In the 1920s, Edwin Hubble used what was then the worlds largest telescope to established that spiral nebulae were whole other galaxies, millions of light years distant from our own. The human understanding of space changed; we saw for the first time the extent of empty space, punctuated by these disc-shaped assemblies of stars, hundreds of billions of stars, which are the galaxies, as OConnor puts it.

In the 1970s, scientists at Bell Labs created a technology that used a charge-coupled device to capture lights as digital images. In 1981, the astrophotographer Jim Gunn used a CCD camera to create a 500 by 500 pixel image of a faint star cluster. He called that camera a nearly perfect device. This same technology, refined, is what kicked off the revolution in consumer-grade cameras and has given us the astounding images of the universe captured by the Hubble Telescope and other instruments. Today, there are dozens of huge telescopes, with top-notch CCD cameras. The question for the team building the LSST, OConnor says, is: Why are we going to the trouble of building another one? What will the LSST do that existing cameras will not?

If you looked up at the sky on a dark night, you might see 2,500 stars with your human eyes. The LSST would see a billion stars, OConnor said this weekend, and those stars would be outnumbered by distant galaxies, three to one. The cameras field of view is ten square degreesabout the size of a dime, held up to the sky. Every photograph we take of that size of the sky gets us another million galaxies, OConnor said.

One of the jobs of the LSST is to survey as many of these galaxies, over as wide a region of sky, as possible.

When the LSST goes into operation, which is scheduled for 2020, it will spend a decade scanning the sky, again and again. Over about 3,000 nights, the instrument will scan and capture each patch of sky one thousand times. Were really going to be making a movie of the universe, OConnor said. The LSST was specially designed to make this possibleit has a relatively wide field of view, it can scan each tiny section of the sky quickly, and it can look deep into the depths of the universe, to capture the faintest, most faraway galaxies.

With the information collected, cosmologists hope to start to better understand dark energy, the force that is causing those distant galaxies to speed away from us at an ever-increasing pace. This line of inquiry has the potential to transform the field of physics. The acceleration of the universe is, along with dark matter, the observed phenomenon that most directly demonstrates that our theories of fundamental particles and gravity are either incomplete or incorrect, the Dark Energy Task Force wrote in 2006. By looking at these faraway galaxies and understanding more about how they move, scientists may unlock fundamental truths about the nature of time, space, matter, and the forces that hold our world together, that have so far escaped our understanding.

Thats the reason theyre building the LSST. One of the reasons, at least.

Heinrich pays a visit to the MRO – El Defensor Chieftain

Posted: August 18, 2017 at 4:57 am

U.S. Sen. Martin Heinrich calls the Magdalena Ridge Observatory a facility with enormous promise.

Heinrich toured the observatory Friday after announcing congressional funding for the observatorys interferometer project.

Were excited to be able to secure some federal funding to keep this moving down the road, Heinrich said. I think that the science of being able to track objects in space is only becoming more important over time, both from a scientific point of view and a defense point of view.

Heinrich said that was the reason $5 million in funding was secured from the Fiscal 2017 budget to help build the Magdalena Ridge Observatory Interferometer. Heinrich saw the first of the telescopes that will become the Magdalena Ridge Observatory Interferometer (MROI). When complete, the telescopes of MROI will be arrayed in a Y-shape and will be able to achieve a resolution 100 times greater than the Hubble Telescope.

Were working on the 2018 bill, Heinrich said. No promises, but were hopeful. A lot of people see the value of this project.

We deeply value the support we receive through Congress and the Air Force (who is working with New Mexico Tech on the project) for this really innovative research that we have here, New Mexico Tech President Stephen Wells added.

The funding will go toward the first telescope on the ridge, which is being moved into place, and the second telescope, which is under construction. The project is expected to cost $25 million when complete.

We dont have the money yet to complete the second telescope, New Mexico Tech Vice President for Research and Economic Development Van Romero said. When we receive that telescope will depend on when we receive the money and how its appropriated.

Romero said another $5 million is needed to get the second telescope on site. The appropriation from the Fiscal 2017 budget is the second round of funding. Another $15 million will be needed to complete the project.

We look forward to receiving the full amount of the appropriation so we can complete the project in a timely way and produce the science that weve promised Congress and our colleagues in the U.K., Wells added.

Cambridge University is working with New Mexico Tech on the project.

It really helps build on the scientific mission of New Mexico Tech broadly, Heinrich said. I have to say, I am amazed at the people I come in contact with who are familiar with the science that New Mexico Tech does, whether thats optics and telescopes, or explosives obviously or the engineering department. The reputation is quite deserved and very impressive.

Heinrich said he ran into people involved with the television show MythBusters last year and they couldnt stop raving about EMRTC and New Mexico Tech and the work they do there.

They were at the White House Science Night and they ended up talking about New Mexico Tech for quite a while, Heinrich said.

Heinrich said he had been to the ridge before, but this was the first time he actually toured the facility.

Its very impressive, Heinrich said. Im looking forward to the day when there are three operational telescopes. Thats when well be able to prove its value and concept nationally, and for that matter, internationally.

The telescopes will be able to track satellites and deep space objects, Romero said.

Eclipse forum planned at MVTHS – Mt. Vernon Register-News

Posted: at 4:57 am

MT. VERNON Mt. Vernon Township High School will host a special education forum on the solar eclipse Sunday night.

The free event will feature hands-on activities for kids, a scientific lecture, and stargazing outside the school, said MVTHS Dramatics Director Mary Beth Mezo, one of the forum's organizers.

What's great about this presentation is it's good for all ages, Mezo said, later adding, Hopefully, some of our out-of-town guests will take advantage of it.

Rend Lake College Associate Professor Greg Hollmann and NASA Specialist Dr. Kenneth Sembach will be featured guests at the forum, which kicks off at 7 p.m. in the MVTHS Schweinfurth Theater. The forum is the final event of the Totality Fest leading up to Monday's solar eclipse.

Hollmann will speak about the significance of the eclipse and offer hands-on activities for kids to teach them about astronomy.

Then Dr. Sembach will take the stage to talk about his work with the Hubble Telescope. Sembach, director of the Space Telescope Science Institute, has worked with the Hubble Telescope for about 16 years and has a leadership role in the new James Webb Space Telescope project.

The stargazing begins at around 9 p.m. as the audience will be invited outside to look at the night sky. Hollmann will provide guidance during the session, pointing out stars and other celestial bodies.

To enhance the experience, all the lights at MVTHS will be shut off, Mezo said. This, plus the high school's isolated location, should give people a clearer view of the sky, Mezo said.

You don't have all the city lights interfering with the night sky, Mezo said.

Mezo said she hopes those in attendance will learn more about the eclipse while enjoying a fun family activity.

She added the new theater is an ideal setting for the forum and it's nice to host an event there for the whole community.

It's something at the theater other than a high school production or a concert, Mezo said. This is the kind of thing that the theater needs to be doing for the community.

Photogram Artist Creates Galaxies Inspired by Hubble Telescope Images in UP TIL NOW – Long Beach Post

Posted: August 11, 2017 at 5:57 pm

Image of Color Bang #50 courtesy of Made by Millworks.

Long Beach native Ross Sonnenberg will show large-scale original photograms, pictures produced with light-sensitive photographic paper without using an actual camera, at MADE by Millworks starting this Tuesday, August 15.

Many of Sonnenbergs photograms are incredibly celestial, with forms resembling planets, solar eclipses, galaxies and stars. While his vision is inspired by actual photos taken by NASAs Hubble Space Telescope, his work on the ground seems to consider his prior abstract painting process, with gestures that seem as emotive as they are spontaneous.

Several of the artists photograms that were created using fireworks have been featured in Harpers Magazine, WIRED and The Creators Project. Using a surprising variety of media, such as sand, colored gels and colored plastic lunch plates, to name a few items, Sonnenbergs photograms contain worlds of their own.

Image taken from @ross.sonnenberg1138.

How did Sonnenberg arrive at the making of photograms? A distinct hardship.

Twenty-four years ago Sonnenberg was getting ready to start film school, with the ultimate goal of embarking on a career within the film industry. When he became ill with a debilitating disease, that dream was quickly extinguished.

It took over eight months for the doctors to figure out what I had, Sonnenberg said in a statement. It turned out to be Systemic Lupus. I had to undergo chemotherapy to stop my immune system from killing me, and I had to say goodbye to my dream of film-making.

After several years of attempting to gain control of the disease and finally finding some balance, Sonnenberg had to find a creative outlet for the myriad ideas trapped in his head. He started painting abstract forms as expressions of his pain and loss, as well as love.

Lupus turned my life into chaos, changing the direction forever, he stated. My art has allowed me to give expression to that chaos. Im pleased to be able to show the many series of art I have created over the past 30 years for the first time."

The opening reception will take place on Saturday, September 2 from 7:00PM to 10:00PM. Ross Sonnenberg: Up Til Now will be on view starting Tuesday, August 15 through Saturday, September 30.

Hubble Telescope sees merging ‘David and Goliath’ galaxy pair – Fox News

Posted: August 10, 2017 at 5:53 am

The Hubble Space Telescope has taken a close look at the fascinating gravitational effects caused by a diminutive dwarf galaxy as it orbits its massive neighbor. The galactic pair will eventually merge, with the dwarf being eaten but it's not going down without a fight.

NGC 1512 is a colossal barred spiral galaxy containing billions of stars, plus active regions of star formation. Hubble, a joint project of NASA and the European Space Agency, can easily detect star formation in the galaxy's outer ring. That region is dotted with many blueish HII-emission regions, meaning that blasts of powerful radiation coming from nearby young stars are ionizing the clouds of hydrogen gas. In this observation of NGC 1512, however, the bright blue inner hub of star formation takes center-stage.

Known as a "circumnuclear starburst ring," this intense star-formation region measures 2,400 light-years across. It is fed by a conveyor belt of gas streaming down the two prominent bars from the galaxy's outer rim to the galactic core (hence the "barred spiral galaxy" designation). Astronomers think that the 400-million-year-old gravitational battle between NGC 1512 and its tiny buddy, NGC 1510 (on the right in the image), is driving the massive galaxy's gas supply and starburst ring, researchers said in a statement.

Although NGC 1510 seems to be holding its own against its neighboring gravitational bully, the unfortunate dwarf galaxy faces the beginning of the end. Already, the bigger galaxy's gravity is dragging extended tendrils of gas from the tiny galaxy, and NGC 1510's stars will eventually assimilate with NGC 1512's stellar metropolis. Astronomers know this because 2015 observations of the massive galaxy revealed that the outer regions of NGC 1512's spiral arms once belonged to another galaxy, one that was cannibalized and ingested a grim fate that also awaits NGC 1510. But in the cosmic ecosystem, this is the galactic cycle of life.

Although the doomed dwarf galaxy is small, it has a big impact on its larger companion, the statement said. Observations of these effects will help astronomers learn more about the dramatic consequences galactic mergers have for star formation in massive galaxies, according to the statement.

The Hubble Space Telescope has taken a close look at the fascinating gravitational effects caused by a diminutive dwarf galaxy as it orbits its massive neighbor. The galactic pair will eventually merge, with the dwarf being eaten but it's not going down without a fight.

The barred spiral galaxy NGC 1512 (left) and the dwarf galaxy NGC 1510 (right) are merging with one another. The duo is 30 million light-years from Earth.
