Saturn Reflects X-Rays from the Sun - Universe Today
Based on new observations from the Chandra X-Ray Observatory, Saturn could act as a mirror to help determine when massive X-ray flares are going off on the Sun. Chandra observed Saturn before and then during a flare and could clearly see X-rays reflected back. A similar situation also happens with Jupiter, so scientists could use the two planets as remote sensing tools to monitor events on the opposite side of the Sun.
