A supernova 'destroyed' some of Earth's ozone for a few minutes in '22

Telescopes detected a supernova explosion 1.9 billion light-years away, known as a gamma ray burst, which was described as the brightest of all time. Scientists have now discovered that this burst caused a temporary depletion of ozone molecules in Earth's upper atmosphere, leading to a measurable change in the number of ionized particles. Although the effect was only detectable for a few minutes and the ozone repaired itself, the discovery highlights how even distant cosmic explosions can influence Earth's atmosphere. The researchers emphasized that this particular event posed no threat to us.
