“The Sun is anything but a stable yellow ball in the sky” — That’s how the narration begins in the NASA video presentation about the STEREO mission. The video itself is well done, with informative commentary and the usual outstanding NASA animated graphics. I highly recommend that you follow the link above and watch the four-minute video.
NASA’s twin STEREO spacecraft completed a series of complex maneuvers Sunday to position the spacecraft in their mission orbits. The spacecraft will be in position to produce the first 3-D images of the sun by April.
As physicists learn more about the Sun and it’s less than subtle behavior, we can expect to be able to “connect the sunspots” and identify the extent to which the Sun influences Earth’s environment and climate.
