Ring of Fire Solar Eclipse This is a rare to see eclipse. The moon will cross in front of the sun not totally blocking out the sun.The sun will be like a ring of fire around the moon. User: barb1 May 18, 2012 8:02 PM

How a Giant Telescope Works From ESOcast, explore the state-of-the-art technology behind the Very Large telescope, which has provided astronomers with an unequalled view of the Universe. To obtain the sharpest images of the sky, the VLT has to cope with two major effects that distort the images of celestial objects. The first one is mirror deformations due to their large sizes. This problem is corrected using a computer-controlled support system — active optics — that ensures that the mirrors keep their desired shapes under all circumstances. The second effect is produced by Earth's atmosphere, which makes stars appear blurry, even with the largest telescopes. Adaptive optics is a real-time correction of the distortions produced by the atmosphere using computer-controlled mirrors that deform hundreds of times per second to counteract the atmospheric effects. As one demonstration of its power the VLT's sensitive infrared cameras, helped by adaptive optics, have been able to peer through the massive dust clouds that block our view to Milky Way's core. The images, taken over many years, have allowed astronomers to actually watch stars orbiting around the monstrous black hole that lies in the center of our galaxy. It was even possible to detect energetic flares from gas clouds falling into the black hole. User: spam_vigilante May 17, 2012 5:54 AM

The Sky Is Calling Us Society has a responsibility to explore. We once were excited about the unknown, relishing every opportunity to turn a new corner, eager to see what lay ahead on the horizon. We've orbited the Earth, walked on the moon and used great machines to see into the far expanses of the Universe. There is so much left to be learned. NASA has been facing massive bugget cuts over the past ten years. Visit theskyiscalling.us to tell Congress that you want more money to be diverted to the program. -- AD: Lauren Geschke | cargocollective.com/laurengeschke CW: Nickolaus Sugai | nicksugai.com Music: Broken Dreams by UNKLE youtube.com/watch?v=RIvcZmSyUL0 Footage: CASSINI MISSION vimeo.com/24410924 Lifetime Collective FM vimeo.com/34522965 Tree of Life (Terrance Malick) youtube.com/watch?v=JmnYqKl1LzE Bluebird vimeo.com/35839533 The Expanding Universe youtube.com/watch?v=LsPqeS5I_QM&feature=related Pathfinder youtube.com/watch?feature=player_detailpage&v=BZpSS4ALKd4 Civil Rights Heroes youtube.com/watch?v=eZhFKV4Q40U&feature=related Right Here All Over vimeo.com/30081785 Where Do We Go From Here? vimeo.com/30778727 Wet on Wet vimeo.com/24741201 Voyagers vimeo.com/13087961 A Blast From The Past: Shuttle Through The Decades vimeo.com/26162174 Yosemite HD vimeo.com/35396305 M A U S I - sol vimeo.com/27889463 PHANTOM WATER EDIT vimeo.com/30830412 *Copyright Disclaimer Under Section 107 of the Copyright Act 1976, allowance is made for "fair use" for purposes such as criticism, comment, news reporting, teaching, scholarship, and research.

Birth of a Great Observatory A road was built in the middle of nowhere. ESO's first telescope took shape, at a steel company in Rotterdam. And in December 1966, the European Southern Observatory opened its first eye on the sky. Europe had embarked on a grand voyage of cosmic discovery. User: Pantufas Mar 30, 2012 10:57 AM

Supernova in M95 (BREAKING NEWS) This is breaking news (on Earth). It happened millions of years ago in space. We have an as-yet unconfirmed supernova in the galaxy M95. This is not our final M95 video, just a news update. Thanks to Nik Szymanek who imaged the object for us at short notice and in testing conditions (what a nuisance Mars can be). Video features Professor Mike Merrifield and Meghan Gray.

NASA: Evolution of the Moon From year to year, the moon never seems to change. Craters and other formations appear to be permanent now, but the moon didn't always look like this. Thanks to NASA's Lunar Reconnaissance Orbiter, we now have a better look at some of the moon's history. User: spam_vigilante Mar 17, 2012 5:07 AM

The Stars as Viewed from the International Space Station Timelapse videos depicting the stars from low earth orbit, as viewed from the International Space Station. Images edited using Adobe Lightroom with some cropping to make the stars the focal point of each shot, and with manipulation of the contrast to bring out the stars a bit more.

Science Bulletins: Space Weather Every 11 years, the magnetic poles of the Sun reverse and start a cycle of high surface activity (flares, CMEs, etc). Space weather has been in the news for the past several days. Once upon a time, back in the twentieth century, the weather was straightforward: it rained or snowed, skies were sunny or cloudy. However, in the twenty-first century—the era of globalization and digitalization—a whole new kind weather is critical to consider: space weather. Space weather is direct product of our local star, the Sun. The Sun continuously sheds its skin, blowing a fierce wind of charged particles in all directions, including Earth's. From time to time, storms on the Sun's surface—solar flares, coronal mass ejections—toss off added masses of energy and ions. When that turbulence slams into Earth, it produces space weather. The consequences can be spectacular, from colorful auroras to satellite, power and communications failures. Space weather isn't new: the Sun has buffeted Earth with solar particles since the planet first formed. What has changed is society. This feature reveals how our increasing use of satellite technology has made us vulnerable to solar storms, and how solar scientists—"space weathermen"—are learning how to predict and forecast the Sun's activity. Science Bulletins is a production of the National Center for Science Literacy, Education, and Technology (NCSLET), part of the Department of Education at the American Museum of Natural History.
