Death Star: Supernova may wipe out the Earth

(THE SUN) — A STAR primed to explode in a blast that could wipe out the Earth was revealed by astronomers yesterday.

It will self-destruct in an explosion called a supernova with the force of 20 billion billion billion megatons of TNT.

New studies show the star, called T Pyxidis, is much closer than previously thought at 3,260 light-years away – a short hop in galactic terms.
