The Fermi glow consists of ultraviolet-glowing particles, mostly hydrogen, originating from the Solar System's bow shock, created when light from stars and the Sun enter the region between the heliopause and the interstellar medium and undergo Fermi acceleration, bouncing around the transition area several times, gaining energy via collisions with atoms of the interstellar medium.
The Fermi glow comprises ultraviolet-emitting particles, primarily hydrogen, originating from the Solar System's bow shock. This phenomenon occurs when light from stars and the Sun enters the area between the heliopause and interstellar medium, leading to Fermi acceleration, causing these particles to bounce multiple times within the transition zone, gaining energy through collisions with interstellar atoms.
