The Einstein Observatory was NASA’s first fully imaging X-ray telescope in space, pioneering high-resolution X-ray astronomy of cosmic sources.
-
C.
XMM-Newton mission
The XMM-Newton mission is a European Space Agency X-ray observatory launched in 1999 to study high-energy phenomena such as black holes, neutron stars, and active galaxies.
-
D.
ASCA X-ray astronomy satellite
The ASCA X-ray astronomy satellite was a Japanese-led space observatory that significantly advanced X-ray spectroscopy of cosmic sources in the 1990s.
-
E.
Great Observatories program
The Great Observatories program is a NASA initiative comprising a suite of space-based telescopes operating across different regions of the electromagnetic spectrum to provide complementary views of the universe.
