A Dwarf Galaxy


NGC 5949 is a dwarf galaxy around 44 million light-years from us. NGC 5949 is a relatively bulky example of a dwarf galaxy with a mass of about one percent of the Milk Way’s. It’s classified as a dwarf because of its relatively small number of constituent stars, but with loosely-bound spiral arms it is also classified as a barred spiral galaxy.

A Double Ring Galaxy


NGC 1512 is a barred spiral galaxy with an unusual double ring structure, one ring around the galactic nucleus and another further out in the main disk. It’s about 38 million light-years away in the constellation Horologium. It’s on a collision course to merge with its smaller neighbor NGC 1510 (on the far right in the picture).
