Chandra X-ray Observatory

Chandra X-ray Observatory is a satellite, inaugurated by NASA in 1999. It was named in honour of Indian physicist Subrahmanyan Chandrasekhar. Chandra Observatory can view the X-ray sky with an angular resolution of 0.5 arcsecs. This is over one thousand times better than the resolution of the first orbiting X-ray telescope. Chandra can also detect variations in X-ray emissions as short as 17 microseconds.

Some missions that Chandra Observatory has been on include X-ray observations of:

• Cassiopeia A
• The Crab Nebula in Taurus
• Galaxies M82 & M31 (Andromeda Galaxy)
• Abell 2142[?]
• Wolf 359
