WebThe team concludes the burst's extraordinary brightness arose from a jet that shot material directly toward Earth at 99.99995 percent the speed of light. At the same moment Swift saw the burst, the Russian KONUS instrument on NASA's Wind satellite also sensed the gamma rays and provided a wide view of their spectral structure. WebAbout 70 percent of all marine life died -- and pretty much everything was marine back then [source: Minard ]. The period has a few of the hallmarks of an increase in radiation, like global cooling, that might point to gamma-ray zaniness. So sure, a gamma-ray burst could wipe out life on earth. It might've even happened once before.
WebThe most powerful gamma ray burst ever recorded is estimated at 8.8 x 10 47 Joules. Which is significantly more than the Earth's gravitational binding energy of 2.5 x 10 32 Joules, even when you consider the fact that half of the GRB energy would presumably be beamed in the opposite direction, away from us.
