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.

Thousands of individual rings make up Saturn’s ring system. Some rings are made of small bits of frozen water, others contain tiny grains of dust, and still others are a mixture of the two. In all, the rings are only a few hundred feet thick.

Scorpius, the Scorpion
Three bright stars form the “head” of Scorpius, the celestial scorpion, while its tail curves away below it in the southern sky of summer. The brightest star in Scorpius is Antares, which is in the middle of the scorpion’s curving body. If you placed this brilliant red star at the center of our own solar system, it would swallow Mercury, Venus, Earth, and Mars, and almost reach Jupiter.
