Terrestrial gamma-ray flashes occur above some thunderstorms and propagate out into space. These high-energy discharges of photons were only discovered less than 25 years ago when a NASA spacecraft ...

Gamma-rays are the highest-energy form of light in the universe. They burst out of distant galaxies following some of space's most extreme events — massive suns exploding, hyper-dense neutron stars ...

On Dec. 14, 2009, while NASA's Fermi flew over Egypt, the spacecraft intercepted a particle beam from a terrestrial gamma-ray flash that occurred over its horizon. Fermi's Gamma-ray Burst Monitor ...

Osaka, Japan – Lightning is a phenomenon that has fascinated humanity since time immemorial, providing a stark example of the power and unpredictability of the natural world. Although the study of ...

Analysis of data from a lightning mapper and a small, hand-held radiation detector has unexpectedly shed light on what a gamma-ray burst from lightning might look like - by observing neutrons ...

SEATTLE – Powerful thunderstorms on Earth can fling beams of antimatter into space, a new study finds. Scientists picked up on the never-before-seen phenomenon by peering at thunderstorms with NASA's ...

HUNTSVILLE, Alabama, January 17, 2011 (ENS) – For the first time, antimatter has been observed occurring naturally on Earth, as beams of antimatter produced above thunderstorms have been documented by ...

Scientists in Japan reported seeing two radioactive weather phenomena at the same time, for the first time, according to a new paper. The observation establishes a link between the two, adding to our ...
