Lots of people have posted this amazing time-lapse video taken from the space station. My favorite part, although this is heavily influenced by the fact that it's my favorite color, are the green auroras dancing over the surface of the earth. I talk in a few places about how those auroras show how the sun's radiation is constantly bombarding us, yet we have this magnetic core that rotates deep inside and protects us from the worst of that radiation. One of the effects of all this is the intense beauty of the auroras.
Someday I'll see one with my own eyes. I live far enough north, but there's always these CLOUDS over Seattle. Who knew??
Oh, and the rainbow around God's throne that looks like an emerald in Revelation? I now think I have a faint, faint idea of what it may look like.
