Astronomers have determined supernova explosions pose yet another threat to planets and their atmospheres. This result comes from analysis of X-ray observations for over 30 supernovae using NASA’s Chandra X-ray Observatory and other telescopes. For some types of supernovas, the researchers found that a torrent of X-rays could be unleashed that last for decades. This type of X-ray onslaught could significantly damage atmospheres of nearby planets, impacting life as we know it. Earth is in a safe space in terms of potentially harmful supernova explosions but may not have been in the past.
