• 7/10/2012 STScI-2012-26 41. Hubble Unmasks Ghost Galaxies Astronomers have puzzled over why some puny, extremely faint dwarf galaxies spotted in our Milky Way galaxy's back yard contain so few stars. These ghost-like galaxies are thought... (More)
• 7/3/2012 STScI-2012-30 42. NASA's Hubble Views a Cosmic Skyrocket Resembling a Fourth of July skyrocket, Herbig-Haro 110 is a geyser of hot gas from a newborn star that splashes up against and ricochets from the dense core of a cloud of molecular... (More)
• 6/28/2012 STScI-2012-23 43. Hubble, Swift Detect First-Ever Changes in an Exoplanet Atmosphere An international team of astronomers using data from the NASA's Hubble Space Telescope has made an unparalleled observation, detecting significant changes... (More)
• 6/26/2012 STScI-2012-19 44. NASA's Hubble Spots Rare Gravitational Arc from Distant, Hefty Galaxy Cluster Seeing is believing, except when you don't believe what you see. Astronomers using NASA's Hubble Space Telescope have found a puzzling... (More)
• 6/19/2012 STScI-2012-27 45. 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 46. 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 47. 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 48. 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)
• 5/4/2012 STScI-2012-22 49. Hubble to Use Moon as Mirror to See Venus Transit This mottled landscape showing the impact crater Tycho is among the most violent-looking places on our Moon. Astronomers... (More)
• 5/2/2012 STScI-2012-18 50. Black Hole Caught Red-handed in a Stellar Homicide 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... (More)
