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 includes ultraviolet-emitting hydrogen particles that originate from the Solar System's bow shock. These particles are produced when light from stars and the Sun enters the space between the heliopause and interstellar medium, experiencing Fermi acceleration as they repeatedly collide with interstellar atoms within the transition zone.
