Explanation: Perhaps the most well-known open cluster in the sky, the bright stars of the Pleiades can be seen without binoculars even from light pollution of the city. With a long exposure of a dark place, however, the cloud of dust that surrounds them becomes very obvious. The zone covers an area of sky framed extended several times the size of the full moon. Also known as the Seven Sisters and M45, the Pleiades are about 400 light-years away in the constellation Taurus. Credit: APOD, NASA.
