Astronomers using data from NASA's Chandra X-ray Observatory and other telescopes have identified a new threat to life on planets like Earth: a phase during which intense X-rays from exploded stars can affect planets up to 160 light-years away.
However, Earth is not in danger of such a threat today because there are no potential supernova progenitors within this distance, according to the study. But it may have experienced this kind of X-ray exposure in the past, says Chandra X-ray Observatory.
