A planet that is snuggled up closely with its host star may be igniting colossal flares that strip it of its own mass.

Recent flybys of the fiery world refute a leading theory of its inner structure—and reveal how little is understood about geologically active moons.

Stars often whip their planets with solar winds and radiation, pull them ever closer with gravity and sear them with heat.
