NASA's STEREO satellite captured the first images ever of a collision between a coronal mass ejection and a comet.
NASA's STEREO Mission is being presented in a new digital 3D film titled "3D Sun."
STEREO observed a nice gathering of solar prominences in profile as they twisted, stretched and floated just above the solar surface.
By combining images taken almost simultaneously from the Ahead and Behind STEREO spacecraft, researchers have generated a 3-D sequence of four images.
A total lunar eclipse, partly visible from every continent around the world, will occur on March 3, 2007.
