NASA TV press conference:
NASA's Chandra Finds Massive Black Holes Common in Early Universe
Wednesday, June 15, 2011 (1:00 p.m. Eastern)
Using the deepest X-ray image ever taken, astronomers found the first direct evidence that massive black holes were common in the early universe. This discovery from NASA's Chandra X-ray Observatory shows that very young black holes grew more aggressively than previously thought, in tandem with the growth of their host galaxies.
A video will air on NASA Television on June 15 (check the NASA TV schedule for additional times and information).
