Happy Birthday, STEREO!
Tomorrow, Oct. 26, is the fifth anniversary of the launch of NASA’s STEREO mission, which has helped scientists understand the structure and evolution of solar storms as they blast from the Sun and move out through space.
In honor of the milestone, NASA will be posting video of STEREO’s discoveries and observations on one of its YouTube pages. Here’s a pretty amazing video taken in 2007. It shows a solar eclipse, a transit of the Moon across the face of the Sun.
