Meanwhile, the newly real particles decay, giving off (among other things) light, X-rays and gamma rays.
The Fermi Space Telescope found hints in 2009 of the telltale pattern associated with positrons in terrestrial gamma rays stemming from lightning storms.

When these electrons are deflected by molecules in the atmosphere, they emit gamma rays.
It can measure the gamma rays that the uranium emits when it spontaneously breaks up in pieces and energy is released we call that fission.
The previously known most distant object was a short-lived gamma ray burst.
The distant storm was below Fermi's horizon, so any gamma rays it produced could not have been detected.
One way to create such short bursts of gamma rays is through the collision — and subsequent annihilation, as the mass of those particles converts into energy — of an electron and a positron.
Some of these gamma rays pass near atomic nuclei, in the process transforming into an electron and a positron, researchers said.
Astronomers keep discovering new noisemakers in space: colliding black holes, glitching pulsars, gamma ray bursts.
It's derived from bee hives in New Zealand and then treated with gamma radiation.
And this object, this pulsar in the Crab Nebula is radiating copious amounts of x-rays, of gamma rays.
Gas from the star falling into the black hole could have triggered the gravitational monster to emit a jet of X-rays and gamma rays that by chance happens to point directly at Earth.
The supernova explosions that create and spread heavy elements also unleash a torrent of high-energy radiation: gamma rays, X-rays, and ultraviolet light.
