New Warning System Could Predict Solar Flares

  Researchers may have discovered a new method to predict solar flares more than a day before they occur, providing advance warning to help protect satellites, power grids and astronauts from potentially dangerous radiation. This image from the Solar Dynamics Observatory’s Atmospheric Imaging Assembly (AIA) shows in great detail a solar flare and its prominence taken [continue reading]

Teamwork: IBEX and TWINS Observe a Solar Storm

On April 5, 2010, the sun spewed a two million-mile-per-hour stream of charged particles toward the invisible magnetic fields surrounding Earth, known as the magnetosphere. As the particles interacted with the magnetic fields, the incoming stream of energy caused stormy conditions near Earth. Some scientists believe that it was this solar storm that interfered with [continue reading]
