Z 229-15 is a ring galaxy in the constellation Lyra.[1] 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 was first discovered by astronomer, D. Proust from the Meudon Observatory in 1990. According to Proust, he described the object as a possible obscured spiral galaxy featuring strong signs of absorption. Additionally, Z 229-15 was also observed through the 1.93-m telescope taken at Observatorie de Haute-Provence.[2]
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.[3]
Z 229-15 has a supermassive black hole at its core.[4][5] The mass of the black hole is solar masses.[6] The interstellar matter in Z 229-15 gets so hot that it releases a large amount of energy across the electromagnetic spectrum on a regular basis.[7]
