Z 229-15

Z 229-15 is a ring galaxy in the constellation Lyra. It is around 390 million light-years from Earth. It has been referred to by NASA and other space agencies as hosting an active galactic nucleus, a quasar, and a Seyfert galaxy, each of which overlap in some way. Z-229-15 has a supermassive black hole at its core, giving it high levels of luminosity. Z 229-15 matter gets so hot that it releases a large amount of energy across the electromagnetic spectrum on a regular basis.

Classification
Z 229-15's classification has been up for speculation for many years. Z 229-15 has been widely called a quasar, and if this is true would make Z 229-15 positively local. Many space agencies, notably NASA, have called it a Seyfert galaxy that contains a quasar, and that, by definition, hosts an active galactic nuclei. This would make Z 229-15 a very uncommon galaxy in scientific terms.
