Hubble found evidence of an isolated black hole roaming around our Milky Way Galaxy.
The black hole is the crushed remnant of a massive star that exploded as a supernova, and the surviving core is several times the mass of our Sun! The black hole also traps light due to its intense gravitational field.
It’s estimated that about 100 million black holes drift through the stars of our galaxy.
This black hole was discovered using gravitational microlensing using Hubble and ground-based telescopes. It’s a runaway black hole drifting through the galaxy at 45 km/s. But what makes this discovery so unique? Find out in this first episode of the Discoveries series.
