Lightning in a thunderstorm changes the electromagnetic field in a way that sparks upward lightning from tall structures.
The Lightning Imaging Sensor on the International Space Station provides an expanded view of global lightning that improves scientific understanding of the Earth as well as public safety.
Concurrent detection from space and the ground of blue optical flashes from streamer corona discharges at altitudes between 8.5 and 14 kilometers and radio waves.
For the first time, the connection between energetic in cloud pulse and terrestrial gamma‐ray flashes is confirmed in the Gamma-Ray Observation of Winter Thunderclouds experiment in Japan.
The world’s largest cosmic ray detector accidentally spotted elves, an unusual lightning phenomenon high in the atmosphere. Now it’s intentionally looking for more.
Charged by thunderstorms and other weather phenomena, the global electrical circuit connects the entire planet.
Lightning on Earth needs just a few simple ingredients to generate a spark. Those ingredients exist throughout the solar system and beyond.
A greater understanding of lightning mechanisms is spurring the development of more accurate weather forecasting, increased public health precautions, and a more sophisticated understanding of lightning itself.
In May, we look at lightning—what it tells us about dangerous weather, how to find it on other planets, and what we might learn if we get all that data in one place.
