ASTRONOMY


Betelgeuse(Alpha Orionis)- is also known as the red supergiant. This star is so big that it's diameter can be easily measured but it is the surface area that is tricky to measure. This star is surrounded by a huge pattern of nested dust and gas shells which are a direct result of aeons mass loss. It is around 1o million years old. This star can be found on the right shoulder of my favorite constellation Orion the hunter. He was a friend of Athena, who was killed by her by accident when her brother turned him into a boar. She placed him in the stars so that she could always see him.
