An Alaskan Aurora, from Tyler Nordgren

If you don't know who Tyler Nordgren is, then you should definitely check out his website. He's an astronomer and artist who's made some of the coolest space-themed artwork I've seen in recent years. Nordgren is up in Alaska right now, kicking off an aurora tour, and shared the above picture to his Facebook profile today. It's definitely a stunning picture of an aurora, with a beautiful mixing of color across the sky.
