Could an exploding star kill all life on Earth? -- If it was close enough, then yes. Astronomers predict that if a supernova were to explode within 30 light years of us, a mass extinction would be possible. X-rays and the more energetic gamma rays brought about by a star’s explosion would destroy Earth’s ozone layer and ionise nitrogen and oxygen in the atmosphere, leading to the formation of large amounts of smog-like nitrous oxide in the atmosphere.
