Pleiades (astronomy)
Pleiades (astronomy)
In astronomy, an open star cluster about 400 light years away from Earth in the constellation Taurus, represented as the Seven Sisters of Greek mythology. Its brightest stars (highly luminous, blue-white giants only a few million years old) are visible to the naked eye, but there are many fainter ones.
It is a young cluster, and the stars of the Pleiades are still surrounded by traces of the reflection nebula from which they formed, visible on long-exposure photographs.
