These 3-D images can be seen with red and cyan 3-D paper glasses. STEREO can see the sun in several different wavelengths and temperatures. Each wavelength allows scientists to see different features on the sun.
Top images were captured by SECCHI/Extreme Ultraviolet Imaging Telescope March 20, 2007. The blue false color image show the sun's atmospheres at a temperatures of 1 million degrees C (171 Å), The bottom image combines 4 different wavelengths into one image. Combining all the wavelengths allows scientist to compare different features and wavelengths. Credit: NASA
STEREO (Solar TErrestrial RElations Observatory) is the third mission in NASA's Solar Terrestrial Probes program (STP). This two-year mission, launched October 2006, will provide a unique and revolutionary view of the Sun-Earth System. The two nearly identical observatories - one ahead of Earth in its orbit, the other trailing behind - will trace the flow of energy and matter from the Sun to Earth. They will reveal the 3D structure of coronal mass ejections; violent eruptions of matter from the sun that can disrupt satellites and power grids, and help us understand why they happen. STEREO will become a key addition to the fleet of space weather detection satellites by providing more accurate alerts for the arrival time of Earth-directed solar ejections with its unique side-viewing perspective.
