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 lightning can be ...

Terrestrial gamma‐ray flashes (TGFs) are brief, intense bursts of high‐energy radiation emitted from thunderclouds, often coinciding with lightning discharges. These phenomena are now understood to ...

The collision of two lightning-bolts-in-the-making spawned an exceedingly brief but extremely energetic flash of gamma rays. This first-of-its-kind observation may help explain an origin of some of ...

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 ...

A rare and extraordinary event has been captured by researchers in Japan, revealing that lightning on Earth can produce gamma-ray bursts—high-energy emissions typically observed from cosmic phenomena ...

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 ...

The Nature Index 2025 Research Leaders — previously known as Annual Tables — reveal the leading institutions and countries/territories in the natural and health sciences, according to their output in ...

The event began with the approach of two opposing electrical discharges: a downward-propagating leader from a thundercloud and an upward leader emerging from a television transmission tower in ...

LOS ALAMOS, N.M., August 21, 2013—The High-Altitude Water Cherenkov (HAWC) Gamma Ray Observatory has begun formal operations at its site in Mexico. HAWC is designed to study the origin of very ...

A NASA ER-2 takes off from MacDill Air Force Base, Fla., to conduct terrestrial gamma-ray flash, or TGF, research in the Gulf of Mexico July 13, 2023. The Airborne Lightning Observatory for TGFs ...
