Dark Lightning

This 'dark opponent' discharges from storm clouds and flings antimatter into space. Astrophysicists and meteorologists are now trying to understand what they have termed ‘dark lightning’. 

Lightning occurs due to charge separation in a cloud. When negatively charged electrons build up at the base of a thundercloud, anything it passes over becomes   positively charged. If the cloud passes over a tall object, like a tall building or tree, these electrons jump, creating the ‘pitchfork’ of light you see streaking across the sky.

Catatumbo ‘Everlasting’ Lightning

It occurs over the mouth of the Catatumbo River where it empties into Lake Maracaibo in Venuzuela, South America. Each year, over 1.2 million bolts of lightning are confined to the mouth of the Catatumbo River - the single highest concentration of lightning in the world.

The Catatumbo lightning, whilst not rare or unusual, is a  remarkable feature in that it persists in the same place night after night. Indeed, the reliability of the storms means that they have historically been used as a maritime navigational aid.

First Global Rainfall and Snowfall Map from NASA's Global Precipitation Measurement Mission

NASA's Global Precipitation Measurement mission has produced its first global map of rainfall and snowfall. The GPM Core Observatory launched one year ago as a collaboration between NASA and the Japan Aerospace Exploration Agency and acts as the standard to unify precipitation measurements from a network of 12 satellites.
