Located in the northwest of the constellation of Taurus, lies an open star cluster containing middle-aged, hot B-type stars. This Cluster, Messier 45 is also known as The Pleiades or the Seven Sisters.
The cluster is dominated by hot blue luminous stars that have formed within the last 100 million years. At a point in the past the Reflection nebulae surrounding the brightest stars was thought to be leftover material from their formation. It is now believed that this is not true. The opinion of astronomers today is that the nebula is an unrelated dust cloud in the interstellar medium that the cluster is currently passing through.
It is thought that the stars that make up the cluster are siblings – that is they were all born at about the same time in gigantic stellar nursery, about 100 million years. These “Blue Giants” are massive, hot, and extremely luminous. As a result, they will exhaust their Hydrogen quickly, and burnout after only a few hundred million years, much shorter than the billions of years our sun will enjoy.
Data was acquired via a robotic telescope within the Telescope Live Network.
