Learn about a 35-year-old mystery--the origin of gamma ray bursts--and how the solution involves some of the most exotic objects in the universe. You'll see how neutron stars and black holes interact to produce these bursts.
The NASA site is a comprehensive presentation of the Swift mission to detect gamma ray bursts, including the timeline, the spacecraft and instrumentation, the science team, background information, and more. Six different "NASA Direct" web videos show the launch and present the science.
Gamma ray bursts are associated with black holes and tremendous energy output. In a striking pair of images on the Swift homepage, a faint galaxy in one image is overwhelmed in the second by light from a tremendous explosion within it. The site explains that this burst might have been caused by a massive star collapsing into a black hole and then exploding, and the early warning of the burst could enable astronomers to observe a supernova explosion from start to finish. Unfortunately this story is still a cliff-hanger, because no follow-up information has been posted on this NASA site since the burst was reported on 2/23/06.
