STEREO consists of two space-based observatories - one ahead of Earth
in its orbit, the other trailing behind. With this new pair of
viewpoints, scientists will be able to see the structure and
evolution of solar storms as they blast from the Sun and move out
through space.
The figure shows a sequence of three 19.5 nm difference images obtained by the EUVI instrument on STEREO taken on May 19, 2007. The images show a tsunami blasting through the Sun's atmosphere at millions of kilometers per hour.
At the largest scale, the Sun's corona (outermost atmosphere) consists of so-called streamers: huge, pointy cones of enhanced density. On a more basic level, everything in the corona is made up of overlapping loops, sometimes with their tops blown indefinitely upward.
