Picture of the day

Lightning is an atmospheric discharge of electricity, which typically occurs during thunderstorms, and sometimes during volcanic eruptions or dust storms. A bolt of lightning can travel at a speed of 220,000 kilometres per hour (140,000 mph), and can reach temperatures approaching 30,000 °C (54,000 °F), hot enough to fuse soil or sand into glass channels.Photo credit: Fir0002
