Astronomers Revealed That Earth Was In Direct Line of Fatal Gamma-Ray Burst

May 30, 2013 16:40 IST

Astronomers revealed the recent potential risk of Earth being hit by fatal gamma-ray burst from the star called Wolf-Rayet star WR 104, which is around 8000 light years away. Astronomers revealed that when the gamma rays would hit Earth, it would devastate around one quarter of atmospheric ozone of the Earth.

Wolf-Rayet star WR 104 would become supernova on any time and this would eventually lead to generation of gamma rays which could reach Earth any time. Astronomer Grant Hill explained that this supernova would explode from tomorrow to 500000 years from today itself. The astronomer also explained that gamma-ray burst as well as optical photons from this supernova could reach the surface of Earth simultaneously.

The revelation about gamma-ray burst from WR 104 was discovered by the University of Sydney astronomer Peter Tuthill in 1998. But Astronomer Grant Hill explained that this burst was dependent on rotation of the star. On looking at the WR 104 as well as its pinwheel, it was found that this is in combat with an inclination of zero. This meant that the Earth was in line of gamma rays from the star.

The gamma ray burst from this star would lead to a 50 percent increase in the UVB radiation.
