ANN ARBOR, Mich.— Using the deepest X-ray image ever taken, a University of Michigan astronomer and her colleagues have 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.

By pointing Chandra at a patch of sky for over six weeks, astronomers obtained what is known as the Chandra Deep Field South (CDFS). When combined with very deep optical and infrared images from NASA’s Hubble Space Telescope, the new Chandra data allowed astronomers to search for black holes in 200 distant galaxies, from when the universe was between about 800 million and 950 million years old.

Asteroids Collide at 11,000 Miles Per Hour; Scientists Study Debris

Scientists have captured and studied the collision of two asteroids for only the second time in the history of astronomy. In the May 20 edition of the Astrophysical Journal Letters (currently online), UCLA’s David Jewitt and colleagues report on observations from NASA’s Hubble Space Telescope of a large asteroid that was hit by a much smaller one.

On Dec. 11, 2010, astronomers noticed that an asteroid known as (596) Scheila had unexpectedly brightened and was sporting short-lived dust plumes. Data from NASA’s Swift satellite and Hubble Space Telescope showed that these changes likely occurred after Scheila was struck by a much smaller asteroid, probably in late November or early December. The shape, evolution and content of the plumes enabled the scientists to reconstruct what occurred. (more…)

CU-Boulder-Led Hubble Astronomy Team Uncovers Evidence of Early Heated Universe

If you think global warming is bad, 11 billion years ago the entire universe underwent what might be called universal warming. The consequence of that early heating was that fierce blasts of radiation from voracious black holes stunted the growth of some small galaxies for a stretch of 500 million years. (more…)

New Hubble Observations of Supernova 1987A Reveal Composition of ‘Star Guts’ Pouring Out

Observations made with NASA’s newly refurbished Hubble Space Telescope of a nearby supernova are allowing astronomers to measure the velocity and composition of “star guts” being ejected into space following the explosion, according to a new study led by the University of Colorado at Boulder.

Microsoft has released the software for its WorldWide Telescope (WWT) program to download and install onto desktops turning computers to function as virtual telescopes to travel through night sky. A fancy not only for kids but for adults as well.
