Impending Catastrophe: Kilonova Space Explosion Threatens Earth's Existence

Scientists have discovered that kilonova explosions, resulting from violent star collisions, could pose a catastrophic threat to Earth due to the release of lethal radiation, including gamma rays and cosmic rays. If a neutron star merger occurs within 36 light-years of Earth, it could cause an extinction-level event by annihilating the ozone layer and exposing the planet to ultraviolet radiation for 1,000 years. Cosmic rays are identified as the most significant threat, while gamma rays and ionizing X-ray emissions also pose dangers. However, kilonovas are rare, and other events like solar flares and asteroid impacts are more likely to be harmful.

Scientists Reassure: Nearby Kilonova Explosion Poses No Threat to Earth's Existence

Scientists have determined that a neutron star collision, known as a kilonova, could potentially cause an extinction-level event if it occurred within 36 light-years of Earth. The resulting radiation, including gamma rays and cosmic rays, could strip the Earth's ozone layer and expose the planet to lethal doses of ultraviolet radiation. However, such a close collision is extremely rare, and other events like solar flares and asteroid impacts are more likely to be harmful. This research has implications for understanding the conditions necessary for supporting life elsewhere in the universe.
