“Red sprites” are short-lived, red flashes that occur about 80 kilometers (50 miles) up in the atmosphere. These electrical discharges can extend 20 to 30 kilometers up into the atmosphere and are connected to thunderstorms and lightning. Red sprites are difficult
Noctilucent clouds (NLCs) turn on every year in late spring, reaching almost full intensity over a period of no more than 5 to 10 days. These electric-blue ice clouds hang 85 km (53 miles ) above Earth’s surface, at the edge of space itself, circling the north and
The shallow Yellow Sea, which has a number of busy ports, usually sees 50 foggy days a year; some weather stations in the area have measured fog on up to 80 days. One of those days was March 28, 2012, when the Moderate Resolution Imaging Spectroradiometer (MODIS) on

High above Earth in the realm of meteors and noctilucent clouds, a strange and beautiful form of lightning dances at the edge of space. Researchers call the bolts "sprites"; they are red, fleeting, and tend to come in bunches. Martin Popek of Nýdek in t
Astronomers in Beijing can’t quite put their finger on the composition or origin of a giant, expanding bubble that appeared Saturday in thee night sky at around 9 p.m. China time. The glowing cloud was seen in several Chinese cities and officials believe it was the
Mysterious and gigantic jets of lightning that shoot up to near the edge of space have now been observed in unprecedented detail, revealing just how much charge they pack and how they form. More than 50 miles (80 kilometers) above Earth's surface, extreme…
On May 10th, a severe storm captured national attention when it dumped golf-ball-sized hail on a Minnesota Twins baseball game.
