The Death Star?

The Death Star?: "The Earth could soon be wiped out by the explosion of a star more than 3,000 light years away, according to American scientists. The star, called T Pyxidis, is set to self-destruct in an explosion called a supernova with the force of 20 billion billion billion megatons of TNT."

Something else to not bother worrying about. We got more down to earth problems to get ready for.
