This swirling mass of celestial gas, dust and stars is a moderately luminous spiral galaxy named ESO 021-G004, located just under 130 million light-years away.

This galaxy has something known as an . While this phrase sounds complex, this simply means that astronomers measure a lot of radiation at all wavelengths coming from the center of the galaxy. This radiation is generated by material falling inward into the very central region of ESO 021-G004, and meeting the behemoth lurking there—a . As material falls toward this black hole it is dragged into orbit as part of an accretion disk; it becomes superheated as it swirls around and around, emitting characteristic high-energy radiation until it is eventually devoured.
