India, April 16 -- Gaia BH3 is 2,000 light years away from Earth

Astronomers have detected the largest stellar black hole with mass 33 times that of the Sun in the Milky Way galaxy. It is also the second closest black hole to Earth, sitting just 2,000 light years away from the planet.

When a star with more than eight times the Sun's mass runs out of fuel, it explodes as a supernova and its core collapses to form a stellar black hole.

So far, studies have suggested that there are around 50 suspected or confirmed stellar-mass black holes in the Milky Way, but there could be as many as 100 million in our galaxy alone, according to NASA .

The new discovered stellar black hole "Gaia BH3" has dethroned Cygnus X-1, which is 21 times as massi...
