At approximately 10,000 light years away, Eta Carinae has been has been observed for millennia by astronomers around the world, and had proved to be a very unusual star. Eta Carinae is a massive star, thought to be approximately 4 million times brighter than our sun. However, observations have shown that Eta Carinae actually fluctuates in brightness. From being one of the brightest stars in the night sky in the early 1843, Eta carina faded to invisibility to the naked eye in 1868, and then reappeared to the naked eye again in the 1990’s.
