We learned why the sun is so hot and why the sunspots are the same too. And we learned about the Earth's movements and the sun's movements. We learned the meanings of different kinds of words like Filament, Photosphere, Lasco, CME, and more. CME stands for Cornal Mass Ejection. And we learned that in the pictures 1cm=2,500,000km. And we learned about Heinrich Kreutz that some comets are named after him .And that is what I did at Goddard.
