The Ultimate Compilation: Unfathomable Z 229-15.

Z 229-15 is a celestial object that is classified as an active galactic nucleus, a quasar, and a Seyfert galaxy all at once due to significant overlap in their definitions. It is located about 390 million light-years from Earth in the constellation Lyra and was imaged in exquisite detail by the Hubble Space Telescope. AGNs are small regions at the heart of certain galaxies that are far brighter than just the galaxy’s stars would be due to the presence of a supermassive black hole at the galaxy’s core. Quasars are a particular type of AGN that are typically both extremely bright and extremely distant from Earth. Seyfert galaxies are active galaxies that host very bright AGNs (quasars) while the rest of the galaxy is still observable.
