Where do X-ray sources get their names?

The Professor
You've probably seen some very strange names for X-ray sources. You may have wondered "How DO they come up with those names?" Well, X-ray sources get their names from the constellations, from famous catalogs, from the satellites that discovered them and their coordinates in Right Ascension and Declination, from other coordinate systems and from the year they were discovered, just to name a few.

Imagine the Universe is a service of the High Energy Astrophysics Science Archive Research Center (HEASARC), Dr. Alan Smale (Director), within the Astrophysics Science Division (ASD) at NASA's Goddard Space Flight Center.
