Scientists have confirmed a record-breaking lightning flash that stretched an astonishing 829 kilometers (515 miles) across the central United States—from eastern Texas to near Kansas City, Missouri. The World Meteorological Organization has officially recognized it as the longest lightning bolt ever recorded. The 2017 event was only recently verified using advanced satellite technology, which allows researchers to track massive storm systems across vast regions. Dubbed a “mega flash,” the phenomenon underscores how space-based lightning instruments are revolutionizing weather research, detecting extreme events far beyond the capabilities of ground-based systems.
