Lightning On Venus

Scientist Christopher Russell, a NASA-sponsored scientist on Venus Express from the University of California, Los Angeles has discovered that there is lightning on Venus. There are only three other plants in our solar system that can generate electricity, Earth, Jupiter and Saturn. The lighting on Venus though is not normal lightning. It is not discharged from water clouds but from sulferic acid clouds. It is important when u find lighting on a new planet because the electrical discharges drive the chemistry of an atmosphere by breaking molecules into fragments that can then join with other fragments in unexpected ways.
