Earth may lie in the path of a lethal gamma-ray burst that could wipe out a quarter of our atmospheric ozone.
Astronomers say WR 104, a Wolf-Rayet star about 8000 light years away, could go supernova any day, which would generate gamma-rays that could reach earth.
“We could see it go supernova anywhere from tomorrow to 500,000 years from now,” said astronomer Grant Hill.
