River of light
I will never get over the wonder that I lived long enough to see photographs taken by a guy sitting in a space station in orbit around our planet. I mean, I'm so old I remember when the whole world stopped to watch John Glenn orbit the earth three times and held their collective breath until it was clear he would live through the end of the ride.
Anyway, I love photos of the Aurora Borealis, and this is surely the very best one I've ever seen. It was tweeted to my computer from outer space. Kids today don't realize what a miracle of technology and science that is.
