Red sprites and blue jets are both atmospheric and electrical phenomena that take place in the upper atmosphere. They take place above normal lightning; Blue jets happen in cone shapes above thunderstorm clouds, and are not related to lightning. They’re blue due to ionised emissions from nitrogen. Red sprites can appear as different shapes and have hanging tendrils. They occur when positive lightning goes from the cloud to the ground.

Icy Finger of Death Filmed for the First Time Like a lightning bolt hurled down from Mount Olympus, an icy “finger of death” strikes at sea life beneath the Antarctic ice shelf in what is surely one of the most jaw-dropping natural history sequences ever filmed.

This incredible image was created on Ikaria island. The photographer set up his camera on a tripod, and then took repeated 20 second exposures. He then combined 70 of them into a single frame, creating this stunning image. The photographs were taken over 83 minutes, and the result was this 'wall of lightning'.

Absolutely spectacular shot of lenticular clouds over the Sandwich islands. Also known as altocumulus standing lenticularis, these are stationary, lens-shaped clouds that form at high altitudes. They are included in the middle layer cloud family because the bases of the clouds are stationed between ~ 2,000 - 7,000 meters. These clouds form when moist air is forced to flow up around mountains and large hills. The water is super cooled and condensed from air below the dew point temperature....
