The phenomenon is underway in Arp 122 – a galaxy that actually contains two galaxies, NGC 6040 and LEDA
The extremely rare collision of two galaxies, at a distance of 570 million light years from Earth, was recorded by the Hubble Space Telescope.
The cosmic phenomenon is underway in Arp 122 – a unique galaxy that actually contains two smaller galaxies, NGC 6040 (a tilted, distorted spiral galaxy) and the globular LEDA.
A monster merger 💫
This #HubbleFriday image features Arp 122, which actually consists of two separate galaxies colliding (seen at right).
Galaxy collisions and mergers are dramatic events, but take place over the course of hundreds of millions of years: https://t.co/Eaac4YBTIN pic.twitter.com/GvNJEVuZkC

NGC 6040 and LEDA are in the process of colliding and merging, and may take hundreds of millions of years to complete due to the vast distances between them.
According to NASA, galactic collisions and mergers are monumentally energetic and dramatic events, but they take place on a very slow timescale.
