A long time ago, in a galaxy far far away, a star exploded and you can see it today!
As reported yesterday, astronomers have detected what appears to be a Type 1a supernova - an exploding white dwarf - in nearby galaxy M82, the closest to us in 40 years. Supernova 2014J, as it's been named, is a little hard to see in small scopes right now, but it's predicted to grow significantly brighter over the next two weeks before it fades away - easy enough to spot in the library's 4.5-inch telescope and even binoculars.
M82, also known as the "Cigar Galaxy" because of its shape, is part of a popular galaxy pair (M81-M82) in a relatively dim region of the constellation Ursa Major, about a fist's width above the bowl of the Big Dipper in the northeastern sky. It's visible by 7:00 or 8:00 p.m. in our region and will be visible throughout the night.
Sky & Telescope has some additional information and star maps to help you find Galaxy M82.
