NGC 4845 (NGC 4910) in NASA/ESA Hubble Space Telescope. It is over 65 million light-years away in the constellation of Virgo (The Virgin).
NGC 4845 has a striking flat and dust-mottled spiral disc surrounding a bright galactic bulge which contains a supermassive black hole inferred from its effect on the galaxy’s innermost stars; these stars experience a strong gravitational pull from the black hole and revolve around the galaxy’s center much faster than otherwise.
From the motion of these central stars, astronomers estimate the mass of the black hole — for NGC 4845, hundreds of thousands of times heavier than the Sun. This technique was used to discover the supermassive black hole at the center of our own Milky Way — Sagittarius A* — which is four million times the mass of the Sun.
In 2013 a new flare at the center of NGC 4845 arose from its central black hole engulfing a brown dwarf star or large planet.
