Hoard of supermassive black holes found

PARIS: A haul of hundreds of expanding supermassive black holes have been found buried deep inside numerous galaxies on the edges of the universe.

The astounding discovery is the first direct evidence that most huge galaxies in the far reaches of the universe generated cavernous black holes during their youth, around 10.5 billion years ago.

Scientists generally agree that the universe as we perceive it came into being about 14 billion years ago.

"Tip of the iceberg"

The findings – reported in the November edition of the Astrophysical Journal – more than double the total number of black holes known to exist at that distance, and suggests that there were hundreds of millions more growing in the early universe.

"We had seen the tip of the iceberg before in our search for these objects. Now, we can see the iceberg itself," said Mark Dickinson of the U.S. National Optical Astronomy Observatory in Tucson, Arizona

New Milky Way map reveals a complicated outer galaxy

The halo of stars that envelops the Milky Way galaxy is like a river delta criss-crossed by stellar streams large and small, according to new data from the Sloan Digital Sky Survey (SDSS-II). While the largest rivers of this delta have been mapped out over the last decade, analysis of the new SDSS-II map shows that smaller streams can be found throughout the stellar halo, said Kevin Schlaufman, a graduate student at the University of California at Santa Cruz.

Hubble Finds Unidentified Object in Space, Scientists Puzzled

from: http://gizmodo.com/5049896/hubble-finds-unidentified-object-in-space

"The object also appeared out of nowhere. It just wasn't there before. In fact, they don't even know where it is exactly located because it didn't behave like anything they know."
