Astronomers at NASA have used the Chandra X-Ray Observatory to conduct a detailed study of an enormous cloud of hot gas enveloping two large, colliding galaxies.
Scientists around the world are celebrating the 50th anniversary of X-ray astronomy this year. Few objects better illustrate the progress of the field in the past half-century than the supernova remnant known as SN 1006.
While performing an extensive X-ray survey of our galaxy's central regions, NASA's Swift satellite spotted the previously unknown remains of a shattered star.
Following a successful launch, NASA's Nuclear Spectroscopic Telescope Array (NuSTAR) has begun its mission to discover secrets of buried black holes and other exotic objects.
NASA's Nuclear Spectroscopic Telescope Array (NuSTAR) may be the size of a refrigerator, but it will undoubtedly help astronomers discover some of the most interesting aspects of our universe.
The mainstream media might not give it much coverage, but information has been slowly leaking out into the public sphere that airport body scanners could be dangerous to people who pass through them. They could be more dangerous than the government previously admitted.
