Sorry, this isn't the supernova you're looking for

If you're scouring the Interwebs hoping to find a dramatic pic of a supernova, sorry, but you're going to have to keep looking. This pic quickly made it to the top of Reddit on Tuesday with the headline, "This is an actual photograph of a star going supernova." Only one problem: It isn't. What this picture shows is Eta Carinae, a pair of stars about 7,500 light years from Earth that have been shedding huge amounts of their mass since first being observed in the late 1600s. The expulsions are actually known as "supernova impostors" since they appear to be supernovae but don't actually destroy the core star. [Source]
