We've looked at a number of volcano images this year, but what strikes me about this one is the surreal quality of the smoke. These images are usually about the lava flow - which does create an interesting focal point, like a doorway of light into the mountain. But the movement of the smoke reminds me of watching clouds changing shape on a summer day. Against the backdrop of stars, this violent act of nature seems like something you could watch while drifting off to sleep.
