Andromeda, Chock Full Of Black Holes
According to data from Chandra, our neighboring galaxy, Andromeda, is absolutely packed full of black holes. 26 black holes candidates have been found in the latest haul from NASA's Chandra X-Ray observatory, taking the total number in the galaxy up to 35.
These observations were compiled from around 13 years worth of data from the observatory, but the results are well worth the wait. 35 black hole candidates is the most ever observed in a galaxy outside of our own Milky Way.
These stellar-mass black holes are formed from the collapse of giant stars and have a staggering mass of around 5-10 times that of the sun.
Andromeda, which lies approximately 2.5 million light years away from our own galaxy is slowly drifting towards the Milky Way and when the two collide, these 35 potential black holes will meet with the considerable number that reside within our own galaxy. Just what happens after these two galaxies meet is not known for sure, but after many, many years, it is thought that the two will form one huge galaxy.
