Seyfert’s Sextet is a group of galaxies about 190 million light-years away in the constellation Serpens Caput. The group appears to contain six members, but one of the galaxies is a background object and another “galaxy” is actually a separated part of one of the other galaxies. The gravitational interaction among these galaxies should continue for hundreds of millions of years. Ultimately, the galaxies will merge to form a single giant elliptical galaxy.
