The Pleiades, M45, is one of the nearest open star clusters. It appears high overhead in the constellation Taurus on winter evenings in the northern hemisphere. Light from the cluster's hot blue stars reflects off of the surrounding interstellar dust cloud and shines as a blue reflection nebula. M45 is about 135 light-years from Earth.
