The Winter Triangle and the Pleiades
With the beginning of fall, the three stars forming the Winter Triangle and the Pleiades are visible to the naked eye each night through most of winter. Looking south, you can spot these features moving slowly east to west during the night.
The Winter Triangle
The Winter Triangle asterism is marked by three bright stars from different constellations: Sirius, the brightest star viewed from Earth is in Canis Major the Great Dog; Betelgeuse is in Orion the Hunter; and Procyon is in Canis Minor the Small Dog. In addition to the red supergiant Betelgeuse, other bright features in Orion include the blue supergiant Rigel and the famous Orion Nebula are visible.
The Pleiades is an open cluster of hundreds of extremely lu-minous blue stars. They appear as a dim, misty haze in the constellation Taurus the Bull. Six of the stars can be distinguished, forming a “Little Dipper” shape. The brightest star, Alcyone, is 1,000 times more luminous than the Sun; the faintest of the six is 40 times brighter. The cluster typically reaches its highest point in the sky around the third week of November. 440 light years away, its stars are roughly 100 million years old and will live another 250 million years. That’s a short lifespan com-pared to our Sun, which is roughly 5 billion years old and is expected to last 5 billion years more.
The Seven Sisters
The Pleiades are also known as the Seven Sisters. In Greek mythology, Atlas the Titan, who carries the heavens on his shoulders, had seven daughters: Maia, Electra, Alcyone, Tay-gete, Asterope, Celaeno and Merope. Hunting in the woods one day, the giant Orion slipped into a glade where the sisters were playing. Enamored, he chased after them for years. They pleaded to Zeus, King of the Gods, to save them from Orion. Zeus turned them into doves, so they could fly away. They flew through misty clouds to hide in their father’s land (today, the Atlas Mountains). But, Orion was undeterred. Zeus then transformed the doves into stars to hide in the heavens. The Orion constellation continues to pursue the Pleiades across the night skies of fall and winter.
Why do we only see six of the Seven Sisters?
Some ancient astronomical records indicate that a visible star in the cluster became faded towards the end of the 2nd millennium BCE. Greek legends say one of the Seven Sisters took a mortal husband, and so her star lost its glow.
