NASA | X-Class: A Guide to Solar Flares

Solar flares, explosive events on the sun's surface, can impact Earth by damaging satellites and power grids. Occurring more frequently during the sun's 11-year activity cycle, they are classified by strength from B to X class, with X being the most powerful. X class flares can cause significant disruptions, including radiation storms and global blackouts. NASA and NOAA monitor these events to provide advance warnings, helping to protect technological infrastructure.
