After all the boozing and barbecuing on America day off from labor, take a sec to look up. What you'll hopefully see is A supernova burning bright more than 21 million light years away.
The type 1a supernova is actually an exploding White Dwarf that scientists discovered last in the Pinwheel Galaxy, and it's the youngest of its kind ever to be discovered. You can find it at home on the handle of the Big Dipper with just a pair of binocs or a simple telescope. It'll burn it's brightest on September 9th, but you won't care as much by then. You'll be working. [Wired]
