Lightning

Like a giant jellyfish floating through the atmosphere, red sprites hover above thunderstorms in two new photographs snapped from space by astronauts aboard the International Space Station.

A zap of lightning can change the very structure of a rock, new research shows.

For the first time, scientists have imaged thunder, shedding light on the physical processes that create it.

A new map shows the distribution of lightning strikes across the Earth over the past two decades.

Hot and humid cities can birth more summer thunderstorms than rural areas in the Southeast.

The sun may be partly responsible for lightning strikes on Earth, and scientists think fluctuations in the sun's magnetic field could be used to predict lightning storms weeks in advance.

Expect a 50 percent increase in lightning strikes within the United States by 2100 if temperatures continue to rise due to greenhouse gas emissions.

A high-speed camera run by the University of Florida's Lightning Research Laboratory caught an unusual bolt from the blue in Gainesville.
