Seyfert's Sextet [SEP] constellation
Seyfert's Sextet
Seyfert's Sextet is a group of galaxies about 190 million light-years away in the constellation Serpens. 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.
Discovery.
The group was discovered by Carl Keenan Seyfert using
NGC 6027
NGC 6027 is a lenticular galaxy that is the brightest member of Seyfert's Sextet, a compact group of galaxies. Édouard Stephan discovered the galaxy in 1882.
