It’s wild that we’re still discovering new weather phenomena, but the gigantic jets seen here were only identified in 2002. This uncommon type of lightning shoots up from the tops of thunderstorms into the ionosphere. The video/image above was caught by cameras normally used to monitor meteors. The jets themselves are red in color, a result of the electrical discharge interacting with nitrogen in the atmosphere. (Video and image credits: b/w – Caribbean Astronomy Society, color – F.

Gigantic Jets
Stormy skies feature much more than the forked cloud-to-ground lightning we’re used to seeing. This composite image shows a rare and recently-recognized type of lightning known as a gigantic jets. This type of lightning travels from the top of thunderclouds, around 16 km in altitude, up to the ionosphere at about 90 km. Their bottoms look a bit like blue jets, while their upper reaches look like red sprites, two other types of unusual lightning. The mechanism behind gigantic jets is a topic of ongoing research, but your best chance at seeing them is watching a distant thunderstorm from a clear vantage. (Image credit: Li X.; via APOD)
