3-D Images of the Sun
The APL-built and -operated Solar TErrestrial RElations Observatory (STEREO) satellites have provided the first 3-D images of the sun. For the first time, scientists are able to see structures in the sun's atmosphere in three dimensions. This new view will greatly aid scientists' ability to understand solar physics, which will help improve space weather forecasting. Shown here is the same image in 2-D image (top) and 3-D (bottom). To view correctly, you need 3-D glasses. For high-resolution versions of these and other 3-D STEREO images, and to download a pair of 3-D glasses, please visit NASA's Web site at http://www.nasa.gov/mission_pages/stereo/main/index.html.

STEREO's First Images
NASA's twin STEREO (Solar TErrestrial RElations Observatory) spacecraft, built and operated by APL, sent back their first images on Dec. 4, 2006. This is a mosaic of the extreme ultraviolet images from the SECCHI/Extreme Ultraviolet Imaging telescope taken on December 4. These false-color images show the sun's atmospheres at a range of different temperatures. For additional details and to download high-resolution versions of this and other data images, please visit the STEREO Science Center, managed by NASA Goddard Space Flight Center, at http://stereo.gsfc.nasa.gov/gallery/gallery.shtml.
During its two-year mission, the twin observatories will explore the origin, evolution and interplanetary consequences of coronal mass ejections. These powerful solar eruptions are a major source of the magnetic disruptions on Earth and a key component of space weather, which can greatly affect satellite operations, communications, power systems, and the lives of astronauts in space.
