From CNN:

"(CNN) There's something unusual happening at the center of the spiral galaxy NGC 3147, and the Hubble Space Telescope caught a good look.

The galaxy, which is 130 million light-years away, contains a supermassive black hole at its heart, as expected. What wasn't expected is the thin disc of material around the black hole."
