Stardust of the Pleiades (M45)
A wide-field HDR image of the Pleiades (also known as the Seven Sisters, or Messier 45 (M45).
The Pleiades is an open star cluster containing middle-aged hot B-type stars, located in the constellation of Taurus. It is among the nearest star clusters to Earth, and is visible with the naked eye. The cluster is dominated by hot blue and luminous stars that have formed within the last 100 million years. Reflection nebulae around the brightest stars were once thought to be left over material from the formation of the cluster, but are now considered likely to be an unrelated dust cloud in the interstellar medium through which the stars are currently passing.
