NASA's Chandra X-ray Observatory obtains the sharpest X-ray images of the sky. It is a general purpose X-ray observatory, which was launched in 1999 and has since then detected X-ray emission from almost all kinds of cosmic objects.

ESA's XMM-Newton is the largest X-ray telescope ever launched and it  consists of three independent X-ray telescopes. XMM-Newton is also a general purpose instrument with larger collecting area than Chandra, but with not as good angular resolution.

DARK uses Chandra and XMM-Newton to study the X-ray afterglow from gamma-ray bursts, the hot gas in clusters of galaxies, and to search for putative X-ray emission from decaying dark matter particles.
