Solar Dynamics Observatory (SDO)

The Sun

Scientists Use NASA Data to Predict Solar Corona Before Eclipse

Our Sun, like many stars, is adorned with a crown. It’s called a corona (Latin for “crown” or “wreath”) and consists of long, thread-like strands of plasma billowing out from the Sun’s surface. The powerful magnetic field of the Sun defines these strands, causing them to ripple and evolve their structures constantly. The strands are […]

Multiple Spacecraft Tell the Story of One Giant Solar Storm

April 17, 2021, was a day like any other day on the Sun, until a brilliant flash erupted and an enormous cloud of solar material billowed away from our star. Such outbursts from the Sun are not unusual, but this one was unusually widespread, hurling high-speed protons and electrons at velocities nearing the speed of […]

NASA’s MAVEN Observes the Disappearing Solar Wind

In December 2022, NASA’s MAVEN (Mars Atmosphere and Volatile EvolutioN) mission observed the dramatic and unexpected “disappearance” of a stream of charged particles constantly emanating off the Sun, known as the solar wind. This was caused by a special type of solar event that was so powerful, it created a void in its wake as […]
