Astrophotographer Cari Letelier caught this amazing shot of the aurora borealis over the Goðafoss waterfall in Iceland. We live in a truly magical world — if science fiction authors made something like this up, you wouldn't believe it'd ever be real. You can check out more of Letelier's astrophotography on Instagram or on her website.
I found this via the Astronomy Picture of the Day site, a gem of the old school web that's been sharing astronomy photos since 1995.
