Astronomers Discover Closest-Ever Black Hole to Earth – Futurism

They're calling it "The Unicorn."Howdy Neighbor

A team of scientists from The Ohio State University (OSU) say theyve found the closest black hole to Earth ever discovered, and its just 1,500 light-years away.

The team decided to name the black hole The Unicorn because of its location in the Monoceros constellation but also because it is, so far, one of a kind, according to a university press release. As for what makes it so unique, the Unicorn is unbelievably tiny for a black hole. With only three times the mass of the Sun, the black hole exists in a category that, until recently, astronomers didnt even believe was physically possible.

The OSU team didnt directly image the Unicorn. But they found something weird going on with a nearby red giant star: An invisible object appeared to be locked into its gravitational pull and exerting such a strong tug of its own that it was physically reshaping the star as it orbited.

The simplest explanation is that its a black hole, study coauthor Todd Thompson said in the release, and in this case, the simplest explanation is the most likely one.

Thompson is OSUs astronomy chair and his new research, set to be published in the journal Monthly Notices of the Royal Astronomical Society, is just the latest piece of his ongoing work to discover and understand these bizarrely tiny black holes. Aside from a scientific oddity, finding black holes like The Unicorn helps to unravel the mysteries of how stars develop and die.

I think the field is pushing toward this, to really map out how many low-mass, how many intermediate-mass, and how many high-mass black holes there are, Thompson added, because every time you find one it gives you a clue about which stars collapse, which explode and which are in between.
