2012 (continued)

• 6/19/2012 STScI-2012-27 11. Most Quasars Live on Snacks, Not Large Meals Black holes in the early universe needed a few snacks rather than one giant meal to fuel their quasars and help them grow, a new study shows. Quasars are the brilliant... (More)
• 6/14/2012 STScI-2012-29 12. Chance Alignment Between Galaxies Mimics a Cosmic Collision NASA's Hubble Space Telescope shows a rare view of a pair of overlapping galaxies, called NGC 3314. The two galaxies look as if they are colliding, but they are actually... (More)
• 5/31/2012 STScI-2012-20 13. NASA's Hubble Shows Milky Way is Destined for Head-on Collision with Andromeda Galaxy NASA astronomers announced Thursday they can now predict with certainty the next major cosmic event to affect our galaxy... (More)
• 5/30/2012 STScI-2012-25 14. Stellar Archaeology Traces Milky Way's History Unfortunately, stars don't have birth certificates. So, astronomers have a tough time figuring out their ages. Knowing a star's age is critical for understanding... (More)
• 3/15/2012 STScI-2012-14 15. Astronomers Using NASA's Hubble Discover Quasars Acting as Gravitational Lenses Astronomers using NASA's Hubble Space Telescope have found several examples of galaxies containing quasars, which act as gravitational lenses, amplifying... (More)
• 3/2/2012 STScI-2012-10 16. Dark Matter Core Defies Explanation in Hubble Image 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... (More)
• 2/17/2012 STScI-2012-11 17. NASA's Hubble Spots a Relic from a Shredded Galaxy Astronomers using NASA's Hubble Space Telescope may have found evidence for a cluster of young, blue stars encircling HLX-1, one of the first intermediate-mass... (More)
• 2/2/2012 STScI-2012-08 18. Hubble Zooms in on a Magnified Galaxy A team of astronomers aimed Hubble at one of the most striking examples of gravitational lensing, a nearly 90-degree arc of light in the galaxy cluster RCS2 032727-132623. (More)
• 1/11/2012 STScI-2012-04 19. Hubble Zooms in on Double Nucleus in Andromeda Galaxy A new Hubble Space Telescope image centers on the 100-million-solar-mass black hole at the hub of the neighboring spiral galaxy M31, or the Andromeda galaxy... (More)
• 1/11/2012 STScI-2012-03 20. Rare Ultra-blue Stars Found in Neighboring Galaxy's Hub Peering deep inside the hub of the neighboring Andromeda galaxy, NASA's Hubble Space Telescope has uncovered a large, rare population of hot, bright stars. (More)
