Get out your binoculars and telescopes. This weekend, a supernova that is closer to Earth than any found in at least the last 25 years will be visible from your back yard.

The violently exploding white dwarf star is brightening in the Pinwheel Galaxy, approximately 21 million light-years away, Wired reports. (Most supernovas spotted by astronomers are around 1 billion light-years away and cannot be seen by amateurs.)
