A Quick Look at Ring Galaxy AM 0644-741
A Quick Look at Ring Galaxy AM 0644-741
Astronomers have used NASA's Chandra X-ray Observatory to discover a ring of black holes or neutron stars in a galaxy 300 million light years from Earth. (2018-09-06)

Introductory Trailer to Chandra

In Florence, Italy, in the year 1609, the world changed. Using a small telescope, Galileo proved that the Earth is not distinct from the universe, but part of it. And he showed that there is much more to the universe than we see with the naked eye.

Est enim GALAXIA nihil aliud, quam innumerarum Stellarum coacervatim consitarum congeries.

In the twentieth century, astronomers made another revolutionary discovery – that optical telescopes reveal only a portion of the universe. Telescopes sensitive to invisible wavelengths of light have detected microwave radiation from the Big Bang, infrared radiation from proto-planetary disks around stars, and X-rays from explosions produced by black holes. On July 23rd, 1999, the most powerful X-ray telescope ever made began its exploration of the hot universe. Chandra, exploring your universe.
