Video about the spiral galaxy Arp 243 (also known as NGC 2623), located in the constellation of Cancer (the Crab). This galaxy is the product of the interaction and collision of two former galaxies, and the images we can see on this video show us the late stages of the merging process with the centres of the original galaxy pair now merged into one nucleus. According to the astronomers of NASA & ESA, stretching out from the centre are two tidal tails of young stars showing that a merger has taken place. During the intergalactic collision, a dramatic exchange of mass and gases initiated star formation as well, as can be seen here in both the tails.
