NASA Researchers Explore Lightning's NOx-ious Impact on Pollution, Climate

Every year, scientists learn something new about the inner workings of lightning.With satellites, they have discovered that more than 1.2 billion lightning flashes occur around the world every year. (Rwanda has the most flashes per square kilometer, while flashes are rare in polar regions.) Laboratory and field experiments have revealed that the core of some lightning bolts reaches 30,000 Kelvin
