Gigantic sunspot, wide enough to fill 15 worlds, hits Earth with powerful X-class solar flare ========== A gigantic sunspot, AR3664, on the surface of the sun ballooned and grew so massive that it can fit 15 Earths and has become the most active one in the current solar cycle. The sunspot released a powerful X-class solar flare towards the Earth, leading to radio blackouts in various areas. The National Oceanic and Atmospheric Administration (NOAA) Space Weather Prediction Center had issued a warning of increased solar flare risk from the Sun. The giant sunspot fired a colossal X-class solar flare on May 9 morning, causing shortwave radio blackouts across parts of Europe and Africa. The sunspot AR3664 is currently 15 times wider than Earth and visible from Earth without magnification. NASA shared images of two powerful solar flares unleashed by the sunspots AR3663 and AR3664. The sun goes through periods of higher and lower activity, and high activity can lead to solar flares or dramatic explosions of energy out from the Sun. #Sunspot #SolarFlare #Xclass #RadioBlackout #Noaa #Nasa https://www.wionews.com/science/gigantic-sunspot-wide-enough-to-fill-15-worlds-hits-earth-with-powerful-x-class-solar-flare-720050
