NASA Reveals Dark Side of the Mystery of Sun's Bursts of Radiation

In addition to the constant emission of warmth and light, our sun sends out occasional bursts of solar radiation that propel high-energy particles toward Earth. These solar energetic particles, or SEPs, can impact astronauts or satellites. To fully understand these...
