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 ...

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 ...

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 ...

For the first time, scientists have caught lightning in the act of unleashing a powerful burst of gamma radiation known as a terrestrial gamma-ray flash (TGF). Researchers at the University of Osaka ...

A particle accelerator operates in Earth’s upper atmosphere above major thunderstorms at energies comparable to some of the most exotic environments in the universe, according to new satellite ...

Victor Pasko, left, professor of electrical engineering in the Penn State School of Electrical Engineering and Computer Science, and Zaid Pervez, a doctoral student in electrical engineering, revealed ...

A multi-sensor detection of an intense gamma-ray flash, which occurs when two lightning leaders collided, has been observed. Observations across a wide radiation spectrum enabled precise measurement ...
