A huge sunspot that dwarfs the Earth is unleashing a series of powerful solar flares as it moves across the surface of the sun, NASA scientists say.
The sunspot AR 1476 was detected by space telescopes on May 5. The huge sunspot is 60,000 miles (100,000 kilometers) across, so large that when it was first seen in views from NASA's Solar Dynamics Observatory spacecraft, mission scientists dubbed it a " monster sunspot."
Earlier this week, space weather scientists predicted the sunspot would erupt with powerful solar flares, and those predictions have since come true. So far, the sunspot has fired off several flares, including a strong solar storm early Thursday.
