So the blast from the thermonuclear explosion could strip away our ozone layer that keeps out deadly space radiation. Life on Earth would then be frazzled.
The doomsday scenario was described yesterday by astronomers from Villanova University, Philadelphia, US.
They said the International Ultraviolet Explorer satellite has shown them that T Pyxidis is really two stars, one called a white dwarf that is sucking in gas and steadily growing. When it reaches a critical mass it will blow itself to pieces.
