Pleiades, in astronomy, a cluster of stars in the constellation Taurus. With a telescope, several hundred stars are visible in the cluster. However, only six stars can be easily seen with the unaided eye. On a very clear night, several more can sometimes be seen. Alcyone is the brightest star in the Pleiades. Bright nebulae (clouds of gas and dust) surround several of the stars in the cluster.
