NGC 4845 a Spiral Galaxy
(also known as NGC 4910) is a spiral galaxy located in the constellation Virgo 47 million light years away

The galaxy has a supermassive black hole at its center with a mass of 300,000M⊙. In 2013, the ESA observed the black hole absorbing matter from a nearby, low-mass object; possibly a brown dwarf star. The observed X-ray flare was caught by the ESA’s INTEGRAL telescope.
