Chandra :: Field Guide to Xray Sources :: The Milky Way
The Local Group contains about 3 dozen known galaxies, clumped in two subgroups around two massive spiral galaxies the Milky Way, and the Andromeda Galaxy. In several billion years it is possible that the Milky Way and Andromeda will collide and merge to form one huge elliptical galaxy, so enjoy the Milky Way while you can!
