Astronomers Discover Surprising Radio Signals Emanating From the Sun
Scientists have discovered radio bursts above a sunspot that resemble radio emissions from auroras on Earth. The pink-purple streaks in this illustration represent the radio emissions, with higher-frequency radio signals in pink, closer to the sunspot, and lower frequencies in purple. The thin lines represent magnetic field lines above the sunspot. The sunspot is the dark region on the Sun at the bottom.
