On Monday, NASA’s Jet Propulsion Laboratory released the first 3-D images of the sun from a pair of spacecraft called Stereo. The spacecraft, which were launched last October, are helping astronomers study and predict gigantic eruptions from the sun. (See “Better Predictions of Space Weather.”) Currently, the nature and causes of these explosions of high-energy particles and magnetic storms are poorly understood. And being able to predict them farther in advance will help prevent damage to satellites orbiting the earth.
There’s a 3D viewer of solar events here — you’ll need red-blue 3D glasses.
