NASA has captured what it looks like when two galaxies collide
NASA has captured what it looks like when two galaxies collide.
The image is of Arp 299, about 140 million light years away from Earth, and has been merging for millions of years.
It was discovered by NASA's Chandra X-ray Observatory that already detected over a dozen objects in Arp 299 that give off large amounts of x-rays.
Scientists actually believe these objects are neutron stars or black holes.
NASA also says that the merging has triggered waves of star formation, making it one of the most powerful nearby star forming galaxies.
When the universe was young there was apparently a high rate of galaxy collisions, but scientists say that they are very hard to observe because they are so far away.
