Caption: A mosaic of the extreme ultraviolet images from STEREO's SECCHI/Extreme Ultraviolet Imaging Telescope taken on Dec. 4, 2006. These false color images show the sun's atmospheres at a range of different temperatures. Clockwise from top left: 1 million degrees K (171 A) 1.5 million K (195 A), 60,000-80,000 K (304 A), and 2.5 million K (286 A).
It with great pleasure that we offer here the very first images taken by the new STEREO spacecraft. STEREO is a new solar mission with two almost identical spacecraft that will provide the first ever 3-D views of the Sun and solar storms. It was launched on October 25, 2006 and the spacecraft are still getting into their observing positions, one ahead of Earth and one behind. (These images are from the Ahead spacecraft.) So far everything has been progressing along without a hitch as testing continues. The images will be twice the size of SOHO images and will provide full disk images of solar features at an unsurpassed level of detail.
However, SOHO will still be providing certain images and data not available through STEREO (as with the MDI magnetogram image seen below).
Together scientists will be able to work with data from both spacecraft in a collaborative effort. You can read more about the STEREO mission here: http://stereo.gsfc.nasa.gov/.
SOHO began its Weekly Pick some time after sending a weekly image or video clip to the American Museum of Natural History (Rose Center) in New York City. There, the SOHO Weekly Pick is displayed with some annotations on a large plasma display.
If your institution would also like to receive the same Weekly Pick from us for display (usually in Photoshop or QuickTime format), please send your inquiry to firstname.lastname@example.org.
