These spectacular pictures show the incredible moment a rare natural phenomenon happens in the night sky. Red sprite lightning lasts only a millisecond and takes place high above a tunderstorm cloud.The breathtaking flashes of light are caused by huge electrical discharges of lightning in the sky. Marko Korosec, 32, was lucky enough to catch these sprites on camera after months of trying. Mr Korosec, from Sezana in Slovenia, took the shots whilst he was following storms in Vivaro, Italy.

“Cassowaries are large, flightless birds related to emus and (more distantly) to ostriches, rheas, and kiwis”, writes Olivia Judson in the September issue of National Geographic magazine. How large? People-size: Adult males stand well over five foot five and top 110 pounds. Females are even taller, and can weigh more than 160 pounds. Dangerous when roused, they’re shy and peaceable when left alone. But even birds this big and tough are prey to habitat loss. The dense New Guinea and Australia rain forests where they live have dwindled. Today cassowaries might number 1,500 to 2,000. And because they help shape those same forests – by moving seeds from one place to another – “if they vanish”, Judson writes, “the structure of the forest would gradually change” too.
