 Composite of a Series of Images Taken From Space Aboard the Station This is a composite of a series of images photographed from a mounted camera on the Earth-orbiting International Space Station, from approximately 240 miles above Earth. Space station hardware in the foreground includes the Mini-Research Module (MRM1, center) and a Russian Progress vehicle docked to the Pirs Docking Compartment (right). Expedition 31 Flight Engineer Don Pettit said of the photographic techniques used to achieve the images: "My star trail images are made by taking a time exposure of about 10 to 15 minutes. However, with modern digital cameras, 30 seconds is about the longest exposure possible, due to electronic detector noise effectively snowing out the image. To achieve the longer exposures I do what many amateur astronomers do. I take multiple 30-second exposures, then 'stack' them using imaging software, thus producing the longer exposure." A total of 47 images photographed by the astronaut-monitored stationary camera were combined to create this composite. Image Credit: NASA

This again adds to the growing evidence that Mars had large volumes of water on its surface in the distant past.Black Hole Caught Red-handed in a Stellar Homicide Wed, 02 May 2012 13:00:00 -0400  Astronomers have gathered the most direct evidence yet of a supermassive black hole shredding a star that wandered too close. NASA's Galaxy Evolution Explorer, a space-based observatory, and the Pan-STARRS1 telescope on the summit of Haleakala in Hawaii were the first to the scene of the crime, helping to identify the stellar remains.

The nebula resides 170,000 light-years away in the Large Magellanic Cloud, a small, satellite galaxy of our Milky Way. No known star-forming region that is inside our Milky Way is as large or as prolific as 30 Doradus.

Mikulski Thu, 05 Apr 2012 11:00:00 -0400  One of the world's largest astronomy archives, containing a treasure trove of information about myriad stars, planets, and galaxies, has been named in honor of the United States Senator from Maryland Barbara Mikulski. Space Telescope Science Institute Announces the 2012 Hubble Fellows Mon, 02 Apr 2012 14:00:00 -0400  The Space Telescope Science Institute (STScI) announces today the selection of 17 new candidates for the Hubble Fellowship Program. This is one of the three prestigious postdoctoral fellowship programs funded by NASA. The other programs are the Sagan and the Einstein Fellowships. STScI administers the Hubble Fellowship Program for NASA. Help Find Hubble's Hidden Treasures Tue, 27 Mar 2012 11:30:00 -0400  NASA's Hubble Space Telescope has made over one million observations during its
more than two decades in orbit. New images are published nearly every week, but
hidden in Hubble's huge data archives are some truly breathtaking images that have
never been seen. They're called Hubble's Hidden Treasures, and between now and May 31, 2012, the European Space Agency (ESA), NASA's partner in the Hubble mission, invites you to help bring them to light. Just explore the Hubble
Legacy Archive (HLA) at http://hla.stsci.edu/, dig out a great dataset, adjust the
contrast and colors using the simple online tools, and submit to the Hubble's
Hidden Treasures Contest Flickr group. For more information about the competition,
visit the Hubble's Hidden Treasures webpage at Astronomers Using NASA's Hubble Discover Quasars Acting as Gravitational Lenses Thu, 15 Mar 2012 09:00:00 -0400  Astronomers using NASA's Hubble Space Telescope have found several examples of galaxies containing quasars, which act as gravitational lenses, amplifying and distorting images of galaxies aligned behind them. Dark Matter Core Defies Explanation in Hubble Image Fri, 02 Mar 2012 09:00:00 -0500  Astronomers observed what appeared to be a clump of dark matter left behind during a bizarre wreck between massive clusters of galaxies. The dark matter collected into a "dark core" containing far fewer galaxies than would be expected if the dark matter and galaxies hung together. Most of the galaxies apparently have sailed far away from the collision. This result could present a challenge to basic theories of dark matter, which predict that galaxies should be anchored to the invisible substance, even during the shock of a collision. NASA's Hubble Reveals a New Class of Extrasolar Planet Tue, 21 Feb 2012 09:00:00 -0500  Observations of the extrasolar planet GJ1214b by NASA's Hubble Space Telescope have come up with a new class of planet, a waterworld enshrouded by a thick, steamy atmosphere. It's smaller than Uranus but larger than Earth. A paper reporting these results has been accepted for publication in The Astrophysical Journal and is available online.
