The study showed the high energy particles emitted from several sources knock electrons off air molecules to produce ions, which are positively or negatively charged particles.
As these high energy particles whip through space, they release radiation in a lighthouse-like beam which lashes across the face of the cool red dwarf star, causing the entire system to brighten and fade dramatically every 1.
Cosmic rays include various high energy particles, and they create a shower of secondary radiation upon impact with the Moon or a spacecraft's shielding.
One of the reasons we are interested in VHE gamma rays is because they act as tracers for high energy particles known as cosmic rays.
