The Pleiades are a group of more than 800 stars located about 410 light-years from Earth in the constellation Taurus. Most skywatchers are familiar with the assembly, which looks something like a smaller, hazier version of the Big Dipper in the night sky.
Also known as the "Seven Sisters" and Messier 45, the object derives its English name from Greek legend. The Pleiades are the seven daughters of the Titan god Atlas and the ocean nymph Pleione. During an ancient war, Atlas rebelled against Zeus, the king of the gods, who sentenced his foe to forever hold up the heavens on his shoulders. The sisters were so sad that Zeus allowed them a place in the sky in order to be close to their father.
The Pleiades are an example of an open star cluster — a group of stars that were all born around the same time from a gigantic cloud of gas and dust. The brightest stars in the formation glow a hot blue and formed within the last 100 million years. They are extremely luminous and will burn out quickly, with life spans of only a few hundred million years, much shorter than the billions of years our sun will enjoy.
