There is a beautiful illusion in the depths of space because of the two galaxies locked together.
Their interaction has formed a near-symmetrical shape that has given the pair its nickname: the Angel Wing.
One of the most significant events in the Universe, a galactic merger, is what the official name of the pair of galaxies is.
When galaxies are drawn together across the gulfs of space-time, they perform an increasingly tight orbital dance before coming together to form one big galaxy.
Most objects are 888-609- 888-609- 888-609- 888-609- 888-609- 888-609- 888-609- 888-609- 888-609- 888-609- 888-609- 888-609- 888-609- 888-609- 888-609- 888-609- 888-609- 888-609- 888-609- 888-609- 888-609- 888-609- 888-609- 888-609- 888-609- 888-609- 888-609- 888-609- 888-609- 888-609- 888-609- 888-609- 888-609- 888-609- 888-609- 888-609- 888-609- 888-609- 888-609- 888-609- 888-609- 888-609- 888-609- 888-609- 888-609- 888-609- 888-609- 888-609- 888-609- 888-609- 888-609- 888-609- 888-609- 888-609- 888-609- Waves of star formation can be caused by shocks in surrounding star-forming gas when the merger takes place.
The mergers are thought to be vital to the growth and evolution of the universe. Not only can the process revive star formation in otherwise quiescent galaxies, but it could also play a role in the expansion of supermassive black holes to even more epic proportions.
The black holes are found at the heart of each galaxy, and merging with other black holes could lead to their incredible size.
In the past, the Milky Way has been involved in a number of accidents. Astronomers can piece together how the merging process occurs by identifying other galaxies that are undergoing the same process.
