APOD 3.6

This picture, "Chasing Carina" caught my eye immediately for several reasons. The picture is very pretty, and has myriad colors within it, though primarily pink-ish and blue. Not only was the picture's beauty what caught my eye, but the article and what the picture deals with is quite interesting too. The picture deals with the Great Carina Nebula, which according to the article, spans a massive 300 light years. This is very relevant to my interests, as we have just identified Carina as a constellation in our quizzes, and also Eta Carina, which is mentioned in this article as well. Eta Carinae is a very interesting anomaly to astronomers, since according to the relevant links, this is a star that has 100 times the mass of the Sun! Also while browsing the embedded links in the article, I learned that Eta Carina is a very peculiar celestial object. It is known for having sudden outbursts of brightness, and then also mysteriously fading as well. Astronomers are not entirely sure why this happens, but they do expect Eta Carina to supernova spectacularly sometime in the next few million years.
