Chandra Telescope Uncovers Deadly Threat to Planetary Life.
TL;DR Summary
A new study using data from NASA's Chandra X-ray Observatory and other telescopes has found that X-rays from supernova explosions could significantly damage the atmospheres of planets within about 160 light-years, potentially impacting life as we know it. Earth is currently in a safe space, but may not have been in the past. The study suggests that the areas within the Milky Way galaxy where conditions would be conducive for life as we know it would be smaller. Follow-up observations of interacting supernovae are urged for months and years after the explosion.
