Rare Black Hole Discovered Near Earth by Hubble Space Telescope

Astronomers have discovered a tiny region with the mass of 800 suns that is creating chaos among nearby stars, which could indicate the presence of an intermediate-mass black hole just 6,000 light-years away in the constellation Scorpius. The discovery could add to the growing evidence that the universe is friendly toward such cosmic middleweights, only a handful of which have been found so far. The team used data from the Hubble Space Telescope and the European Space Agency's star-mapping Gaia spacecraft to study the chaotic motion of stars at the center of a nearby star cluster called Messier 4.
