NASA Scientists Catch Unique Gamma-Ray Burst |
[24 May 2005] - After 30 years, they finally caught one. Using the Swift satellite, scientists for the first time detected and pinned down the location of a so-called "short" gamma-ray burst, one lasting only 50 milliseconds.
Newly Seen Force In Star Formation May Help Gravity |
[26 April 2005] - Like viewing a baby's first ultrasound, scientists have pierced through a dusty stellar nursery to capture the earliest and most detailed view of a collapsing gas cloud turning into a star.
New Black Hole Census Reveals Major Undercount and Great Extinction |
[17 March 2005] - Scientists using NASA's Chandra X-ray Observatory and other world-class facilities have discovered that the total number of massive black holes in the Universe is 75 percent more than what was previously estimated. This new black hole census, a compilation of five years of observations, dramatically alters theories of how galaxies form and evolve.
Cosmic Explosion Among the Brightest in Recorded History |
[25 February 2005] - Scientists have detected a flash of light from across the Galaxy so powerful that it bounced off the Moon and lit up the Earth's upper atmosphere. The flash was brighter than anything ever detected from beyond our Solar System and lasted over a tenth of a second. NASA and European satellites and many radio telescopes detected the flash and its aftermath on December 27, 2004.
A Race Around a Black Hole |
[20 January 2005] - So you think rockets are fast? Scientists have spotted something
going much faster. Like state troopers on a highway, these scientists
used a "speed gun" to clock clumps of hot iron gas whipping around a
black hole at 20,000 miles per second - over 10 percent of light
speed. At that speed, you could get to the moon in about 10 seconds.
