NGC 7007
Galaxy in the constellation Indus
NGC 7007 is a barred lenticular galaxy with a small bar, around 100 million light-years away from Earth in the constellation Indus. It was discovered by astronomer John Herschel on July 8, 1834. The galaxy is a type 2 seyfert galaxy, and is host to a supermassive black hole with an estimated mass of 4.9 × 107 M☉.
Like all lenticular galaxies, NGC 7007 has a classical disk similar to most galaxies of its type, having a nearly spherical bulge. Unlike most galaxies of its type, the pattern of dust in NGC 7007 is not circular and continuous surrounding the bulge but shows breaks in its structure. These dust lanes also appear to form dusty spiral arms similar to the Sa galaxies NGC 2855, NGC 4984, and NGC 7377.
NGC 7007 is an isolated galaxy, with it a part of the Telescopium−Grus Cloud, a galaxy filament.
