Closest Known Black Hole to Earth Identified Using ESA’s Gaia Astrometry Mission

Posted by in category: cosmology

Using data from ESA’s Gaia astrometry mission, astronomers have identified the closest known black hole.

A black hole is a place in space where the gravitational field is so strong that not even light can escape it. Astronomers classify black holes into three categories by size: miniature, stellar, and supermassive black holes. Miniature black holes could have a mass smaller than our Sun and supermassive black holes could have a mass equivalent to billions of our Sun.
