Potential, A very rare collision Between two decaying spaces Performer inside milky way the galaxy may strip it away earth of its protection ozone layer and provoke a crowd extinction all of life New research suggests that different forms exist on Earth.
Such an explosionScientists, including those at the University of Illinois at Urbana-Champaign in the US, said that if it occurred very close to Earth, it could pose a danger to life on Earth.
Research that has not yet been peer-reviewed is arXiv Preprint servers could help determine the chances of life surviving on other worlds near these stellar collision events.
Scientists say the biggest threat from these stellar collisions is the bursts of radiation they produce, such as gamma rays and X-ray afterglows. “Ionizing radiation from these sources could be dangerous to life on Earth-like planets if they are too close,” the researchers said in their study.
Based on an analysis of what is known from the first ever detected neutron star collision, scientists studied the potential for these events to affect Earth. A wonderful event called GW170817.
Researchers say the powerful gamma rays could cause burns to living organisms within a small radius of about 297 light-years (97 parsecs) from such an explosion.
Scientists said that if Earth were in such a zone, the radiation would remove ozone from Earth’s stratosphere and it could take years to recover.
Scientists say X-rays from a kilonova’s afterglow tend to last longer than gamma-ray radiation and may therefore be more lethal, although the life-destroying effects last about 16 light years. It added that it would remain within the range of
“For baseline kilonova parameters, we found that X-ray emissions from afterglow can be lethal up to 5pc, and off-axis gamma-ray emissions can threaten ranges up to 4pc. ‘ pointed out the scientists.
“The greatest threat arises years after the explosion from cosmic rays accelerated by kilonova explosions, which can have deadly effects up to 11 percent of the distance,” the researchers said.
However, the study warned that the findings had “significant uncertainties” and depended on “viewing angle, ejected mass, and explosion energy.”
Because kilonova events are rare, the researchers also said such stellar collisions “do not pose a significant threat to life on Earth.”
“Binary neutron star mergers are rare and have a narrow range of lethality, meaning they probably do not pose a significant threat to life on Earth,” the researchers said.
“We found that the average recurrence time of a fatal merger at the Sun’s location is much longer than the age of the Universe.
“But even if it did not cause a mass extinction, a nearby kilonova event would be visible on Earth. It would likely cause a disruption in technology immediately after the merger and would remain bright in the sky for a month or more.” said the scientists.
