A full understanding of how lightning forms in the clouds has eluded scientists, but new research promises to solve this ...

These "empty-sky" gamma-ray bursts, as some astronomers call them, have presented an ongoing cosmic mystery for more than 60 years.

“We are currently looking at producing maps of the gamma-ray sky that can be used to inform upcoming gamma-ray observations from next-generation telescopes. This includes the Cherenkov Telescope ...

"We found a gamma-ray dipole, but its peak is located in the southern sky, far from the CMB's, and its magnitude is 10 times greater than what we would expect from our motion," said co-author ...

NASA's Fermi Gamma-ray Space Telescope team has produced a 14-year time-lapse movie showcasing the dynamic gamma-ray sky. The footage, created from the data collected by Fermi's Large Area ...

The sky is ablaze with explosive, invisible gamma-rays (shown here in yellow and red). According to a new study, some of those rays may be the products of dark matter.(Image credit: NASA Goddard) ...

“The gamma-ray sky is notoriously variable and extremely unpredictable,” says Anthony Dean, University of Southampton, UK, one of the original proposers of the Integral mission.
