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.
