Sagittarius, the Archer

Sagittarius is one of the most interesting regions of the sky. The center of our Milky Way galaxy lies inside Sagittarius, about 26,000 light-years away. The constellation also contains several globular clusters — tightly packed collections of hundreds of thousands of stars. Its brightest stars form the shape of a teapot, and the constellation slides low across the southern sky of summer.
