One of the YouTube sites I subscribe to is that of the European Southern Observatory, which I first found out about via reader Amy Carparelli. Their ESOcasts, as they call their channel, are full of fascinating information and beautiful images. The latest one, about the phenomenon Zodiacal Light, has just been released and is as wonderful as always. Hint: it’s even better if you watch it on full screen.

Watching the ESO videos always fills me with awe about what a wonderful universe we live in. Who needs a god when you have reality like this?
