NASA'S Hubble Provides First Census of Galaxies Near Cosmic Dawn
Miércoles, 12 Diciembre, 2012 Astronomía

Using NASA's Hubble Space Telescope, astronomers have uncovered a previously unseen population of seven primitive galaxies that formed more than 13 billion years ago, when the universe was less than 4 percent of its present age. The deepest images to date from Hubble yield the first statistically...

Astronomers Catch Jet from Binge-Eating Black Hole
Miércoles, 12 Diciembre, 2012 Astronomía

Back in January, a new X-ray source flared and rapidly brightened in the Andromeda galaxy (M31), located 2.5 million light-years away. Classified as an ultraluminous X-ray source (ULX), the object is only the second ever seen in M31 and became the target of an intense observing campaign by orbiting...
