Intense Solar Flare Unleashed from Unruly Sunspot

An intense solar flare took out low-frequency radio communications over South America and the Atlantic Ocean earlier today (Sept. 28), and the unstable sunspot is likely to erupt again. NASA's Solar Dynamics Observatory spacecraft captured an amazing video of the solar flare from space. The explosion unleashed extreme ultraviolet radiation that rushed over the Earth, officials at the National Oceanic and Atmospheric Administration's Space Weather Prediction Center said in a statement.
