Hubble Views an Intriguing Active Galaxy

Quote

Spiral galaxy: 2 almost-straight arms coming from the left and right of the golden core that meet a starry, bluish ring around the edge. A faint light halo surrounds the galaxy. One bright star, a few small stars and galaxies all on a black background.

This luminous image from the NASA/ESA Hubble Space Telescope shows Z 229-15, a celestial object that lies about 390 million light-years from Earth in the constellation Lyra. Z 229-15 is one of those interesting celestial objects defined as several different things: sometimes as an active galactic nucleus (an AGN); sometimes as a quasar; and sometimes as a Seyfert galaxy. Which of these is Z 229-15 really? The answer is that it is all these things all at once, because these three definitions have significant overlap.
