Milky Way over fields. The Milky Way is our galaxy seen from the inside, forming a band of stars and nebulae stretching across the sky. The brightest star, at left, is Sirius. The Rosette and Orion nebulae (both red) are to its right. The blue cluster at centre is Pleiades, or the Seven Sisters. The Heart and Soul nebula (red) is at right near the tree.
