Talk about a heated situation. The sun unleashed two colossal solar flares within seven hours of each other this week, triggering radio blackouts across parts of Earth. Solar flares are strong, powerful explosions of energy that have the potential to wreak havoc on radio communications, electric power grids and navigation signals — and can pose potential risks to spacecraft and astronauts. The superheated fireworks-like display, first commencing on April 23, was captured in striking imagery by the National Aeronautics and Space Administration (NASA). The first “intense” flare peaked at 9:07 p.m. ET on April 23, with the second following seven hours later at 4:13 a.m. ET April 24, according to NASA .
