  • Scientists from the University of Alaska were studying a massive hailstorm in Arkansas from a plane when they saw rays of blue light discharging far above the tops of clouds. The rays were traveling at 216,000 mph. Blue jets are rare and are barely seen with the naked eye. They may be linked to powerful hailstorms.
