Distant Supernova , Temporarily 'Destroyed' , Earth's Upper Atmosphere.<br />In October 2022, humanity got a taste of a cosmic <br />disaster after a powerful supernova about <br />1.9 billion light-years away rocked the universe.<br />Futurism reports that the massive <br />burst of gamma rays produced by the <br />stellar explosion bombarded Earth. .<br />Astronomers dubbed the supernova "BOAT," <br />which stands for "brightest of all time.".<br />According to a 'New York Times' report, <br />the blast was so powerful that it took out <br />a chunk of the Earth's upper atmosphere.<br />The ozone was partially depleted <br />— was destroyed temporarily. , Pietro Ubertini, an astronomer at the National Institute of Astrophysics in Rome, via Futurism.<br />Pietro Ubertini, an astronomer at the National Institute <br />of Astrophysics in Rome, says the ozone layer <br />managed to repair itself in a matter of minutes.<br />However, according to Ubertini, <br />the blast could have caused a "catastrophe" <br />had it occurred closer to Earth.<br />Futurism reports that the latest event is the first <br />time scientists have gathered evidence that suggests <br />distant supernovas can impact Earth's ionosphere.<br />However, scientists say that the chances of <br />a catastrophic cosmic event capable of taking out <br />Earth's atmosphere for a prolonged time remain slim. .<br />The incredibly rare type of celestial <br />event is estimated to only occur <br />once every 10,000 years.<br />The team's findings were <br />published in the journal 'Nature.'
