Try Xamin, the New HEASARC Discovery and Data Retrieval System
A faster, more powerful way to access data from the HEASARC
|
The High Energy Astrophysics Science Archive Research Center (HEASARC) is the
primary archive for NASA's (and other space agencies') missions dealing with
electromagnetic radiation from
extremely energetic phenomena ranging from
black holes to the Big Bang. Since its
merger with the Legacy Archive for Microwave Background Data Analysis (LAMBDA) in 2008, the HEASARC's
holdings contain data
obtained by NASA's high-energy astronomy missions observing in the
extreme-ultraviolet (EUV), X-ray, and gamma-ray bands, as well as data from
missions, balloons, and ground-based facilities that have studied the relic
cosmic microwave background (CMB).

- News Feature: NASA Builds Unusual Testbed for Analyzing X-Ray Navigation Technologies (22 May 2013)
Pulsars have a number of unusual qualities: like zombies, they
shine even though they are technically dead, and they rotate rapidly, emitting
powerful and regular beams of radiation that are seen as flashes of light,
blinking on and off at intervals from seconds to milliseconds. A NASA/GSFC
team has built the Goddard X-ray Navigation Laboratory
Testbed to simulate these distinctive pulsations.
