Chandra is one of NASA's Great Observatories and the most powerful X-ray telescope, with eight times the resolution of any previous X-ray telescope and able to detect sources more than 20 times fainter. Chandra detects cosmic X-rays produced where matter is superheated by extreme gravity, magnetic fields, or even explosions.
Launched: July 23, 1999
