Seven sisters

The Pleiades (M45) is the most famous star cluster in the sky. It lies 444 light-years away in the constellation Taurus the Bull. The clouds of gas seen in this image are not connected to the stars, but are a dust cloud through which the cluster is passing. Dave Doctor from Las Cruces, New Mexico

Old friend

The Orion Nebula (M42) may be the most photographed deep-sky object of all. It’s a huge emission nebula and star-forming complex. In addition to the glowing hydrogen, however, the object also has regions of both reflection and dark nebulae. James Esch from Lovettsville, Virginia
