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 period during which intense X-rays from exploded stars can affect planets over 100 light-years away. The finding, published recently in The Astrophysical Journal, has implication for the study of planets outside the solar system and their habitability.
