Blue jets are similar to red sprites
, but they're negatively charged and appear as cones of blue light that occur lower in the atmosphere.
The beautiful phenomenon called red sprites is seen very rarely.
According to (http://www.livescience.com/39033-red-sprites-lightning-photos.html) LiveScience , red sprites take many shapes, they look like carrots, crowns etc.
The hypothesis to be tested here is whether the form of some Australian Aboriginal figurative paintings in the Kimberley and the Northern Territory, known as Lightning Figures, show remarkable resemblance to strange upper atmospheric phenomena associated with thunderstorms, such as Red Sprites. These phenomena always appear during thunderstorms, but they are different from the common cloud-to-earth lightning.
Atmospheric phenomena: Red Sprites, Elves and Blue Jets
Canadian artist Peter McLeish will be at the Great North Museum: Hancock to give a public lecture on his work on the electrical discharges called red sprites.
Before these images were captured, red sprites were considered to be UFOs by many pilots.
At the same time as blue jets were verified, scientists also collected evidence of "red sprites
", a form of lightning which appears red in colour and goes from the tops of clouds to as high as the ionosphere - an ionized layer 90 km above the Earth's surface.
Only in the last few years have scientists discovered these red sprites
and much rarer flares, called blue jets (SN: 12/17/94, p.405).
These researchers went in search of red sprites
, a recently discovered phenomenon that has yet to yield to scientific explanation.
At a meeting of the American Geophysical Union in San Francisco last week, researchers unveiled theories to explain the phenomena, dubbed red sprites
and blue jets.
