This weekend NASA’s Solar TErrestrial RElations Observatory (STEREO) spacecraft captured comet Lemmon at it traped across the face of the Sun.
Its like 3D! Of course that is the whole point of the STEREO spacecraft. The two nearly identical spacecraft – one ahead of Earth in its orbit, the other trailing behind – are normally used to trace the flow of energy and matter from the Sun to Earth. STEREO has revealed the 3D structure of coronal mass ejections; violent eruptions of matter from the sun that can disrupt satellites and power grids.
We haven’t known this much about the star that gives us life ever. But the images they provide are pretty spectacular as well.
Hopefully, we will get some great shots of ISON from STEREO as well. Wow, I feel like I am back in the Navy using all these acronyms.
