Terrestrial gamma-ray flashes TGFs are burst-like emission with their photon energy extending up to 20 MeV that last for several hundred microseconds, coincident with lightning discharges.

Video: Gamma ray burst.
The strongest explosions in the universe produce even more energetic radiation than previously known: Using specialised telescopes, two international teams have registered the highest energy gamma rays ever measured from so-called gamma-ray bursts, reaching about 100 billion times as much energy as visible light. The scientists of the H.E.S.S. and MAGIC telescopes present their observations in independent publications in the journal Nature. These are the first detections of gamma-ray bursts with ground-based gamma-ray telescopes. DESY plays a major role in both observatories, which are operated under the leadership of the Max Planck Society.

Gamma ray astronomy looks at Gamma ray wavelengths.
If your eyes could see only high energy Gamma-rays through the Earths atmosphere then this is how the night sky would look like. A satellite above the Earths atmosphere sent the data that made this image.
All sky survey showing gamma-ray emissions at energies above 100 MeV.
The Gamma Ray telescope in space known as EGRET (Energetic Gamma Ray Experiment Telescope) measured Gamma Rays with energies ranging from 30 million electron volts (30 MeV) to 30 billion electron volts (30 GeV) in an all sky survey.
The Yellow colour indicates the strongest (brightest) emissions.
The Blue colour indicates the weakest (faintest) emissions.
The plane of our galaxy called "The Milky Way" shows a strong source of diffuse and resolved emissiondue to cosmic ray interactions with the interstellar medium.
The Vela, Geminga, and Crab pulsars are clearly visible as bright knots of emission in the galactic plane in the right.
The gamma-ray blazar 3C279 is seen as the brightest knot of emission above the plane.
