Stereo Sun

NASA put 2 STeReO (Solar Terrestrial Relations Observatory) probes in opposite locations to study the Sun, wich will  take pictures further, in real time, of the two hemispheres of the Sun.
Thus, we can know what happen simultaneously across all the Sun's surface.

The forecasting benefits aren't limited to Earth.

"With this nice global model, we can now track solar storms heading toward other planets, too," points out Guhathakurta. "This is important for NASA missions to Mercury, Mars, asteroids … you name it."
