9/6/2012STScI-2012-389.Odd Galaxy Couple on Space Voyage
Two very different galaxies drift through space together in this image taken by NASA's Hubble Space Telescope. The peculiar galaxy pair is called Arp 116. Arp 116 is composed... (More)
7/10/2012STScI-2012-2610.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)
6/19/2012STScI-2012-2711.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)
6/14/2012STScI-2012-2912.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)
5/30/2012STScI-2012-2514.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)
