Here's what happens when lightning doesn't hit the ground

Everyone loves a lightning show: big bolts of electricity heading to Earth. But there’s an entire display above those billowing masses that you are probably missing. In 2001, researchers scanning the sky with a low-light camera at Puerto Rico’s Arecibo Observatory noticed something bizarre: Lightning exploding from a cloud’s top and heading straight for space. The trajectory was baffling. Thunderbolts form when a negative electrical charge—gathered from an incoming storm—builds up near the bottom of a cloud. If enough energy accumulates, it breaks free, sending the classic bolt to Earth. More often, however, the electrons stay in the cloud, traveling...

Rare, Colorful Lightning Sprites Dance Over Hurricane

As Hurricane Matthew intensified into a Category 5 storm in the Caribbean this weekend, the tempest also produced vibrant colors in the sky. The rare atmospheric phenomena, known as lighting sprites, were photographed by an observer about 400 miles southwest of Puerto Rico. The lightning sprites were seen as fleeting flashes of brilliant red light above the clouds. Sometimes called "upward lightning" and "cloud-to-stratospheric lightning," sprites are momentary bursts of electricity that can literally reach the edge of space, about 50 miles above the ground. They're rarely documented because they are so short lived (typically about 10 milliseconds) and are...

World record: Bolt of lightning was 200 miles long, experts say

Lightning doesn't strike the same place twice-- or so the expression goes-- but sometimes it does something amazing enough to break a record. That’s the case with two extraordinary bolts that the World Meteorological Organization has ruled are both the longest in length and duration on the books. In June in Oklahoma in 2007, a bolt of lightning that was an incredible 199.5 miles long and had a duration of nearly 6 seconds struck across the state horizontally from east to west, according to the WMO, a United Nations agency. And in the south of France in August, 2012, a...

“Unprecedented” Mass Kill of 323 Reindeer in Norway — Why Did Large Antlers Come Off?

September 1, 2016 Fairbanks, Alaska - Earthfiles contacted Knut Kielland, Ph.D., Prof. of Ecology at the University of Alaska-Fairbanks Arctic Biology department, on August 31, 2016, to ask about the large antlers disconnected from some males in the 323 reindeer herd that all fell dead at once, even on top of each other, on Friday, August 26th, in Hardangervidda National Park, Norway. Prof. Kielland said, “I have no idea why so many antlers would be off. I saw that myself in the video of the mass kill and have never seen anything like this before.” One of Prof. Kielland's colleagues,...
