NASA-led firefly mission to study lightning (w/ Video)
Somewhere on Earth, there's always a lightning flash. The globe experiences lightning some 50 times a second, yet the details of what initiates this common occurrence and what effects it has on the atmosphere ...
Scientists detect dark lightning linked to visible lightning
(Phys.org)—Researchers have identified a burst of high-energy radiation known as 'dark lightning" immediately preceding a flash of ordinary lightning. The new finding provides observational evidence that ...
Lightning really does make mushrooms multiply
Lightning sprites are out-of-this-world
Only a few decades ago, scientists discovered the existence of "sprites" 30 to 55 miles above the surface of the Earth. They're offshoots of electric discharges caused by lightning storms, and a valuable window ...
Study explains the mystery of ball lightning
(Phys.org)—Sightings of ball lightning have been made for centuries around the world – usually the size of a grapefruit and lasting up to twenty seconds – but no explanation of how it occurs has been ...

X-rays from lightning photographed
Using a custom-built camera the size of a refrigerator, Florida researchers have made the world's first crude pictures of X-rays streaming from a stroke of lightning.
Lightning’s Mirror Image, Only Much Bigger (w/ Video)
(PhysOrg.com) -- With a very lucky shot, scientists have captured a one-second image and the electrical fingerprint of huge lightning that flowed 40 miles upward from the top of a storm.
Alaska tundra shows surprising resilience after unprecedented fire
Despite the size and severity of the massive 2007 Anaktuvuk River fire on Alaska's North Slope, much of the arctic vegetation has recovered and the tundra is likely to return to its pre-fire condition according ...
Laser lightning rod: Guiding bursts of electricity with a flash of light
Lightning is a fascinating but dangerous atmospheric phenomenon. New research reveals that brief bursts of intense laser light can redirect these high-power electrical discharges.
Some UFOs may be explained as ball lighting
90 million laser shots bring wind satellite back on track
(Phys.org) —Developing new ways of monitoring Earth is always demanding, but ESA's Aeolus mission has faced some particularly difficult technical challenges. However, with the success of intense high-energy ...
