Chandra Sees Stellar X-rays Exceeding Safety Limits - Astrophysics/Planetary Science

Chandra Sees Stellar X-rays Exceeding Safety Limits: Astronomers have made the most extensive study yet of how magnetically active stars are when they are young. This gives scientists a window into how X-rays from stars like the Sun, but billions of years younger, could partially or completely evaporate the atmospheres of planets orbiting them.
