The Black Hole dubbed BH1 was discovered by a team of astronomers using the European Space Agency's Gaia satellite, which is designed to precisely measure the positions and movements of stars in the Milky Way galaxy. BH1 is located in just 1560 light years away from the Earth in the direction of the constellation of Echus, making it the closest black hole ever detected. In addition to BH1 Gaia also found the second closest black hole to Earth dubbing it to Gaia BH2, which is 3,800 light years away in the constellation centuries. Remarkably scientists said that both black holes are in Earth's cosmic backyard. European Space Agency launched the Gaia mission in 2013 for a comprehensive stellar census.
