Nocturnal: Scenes from the Southern Night

Explanation: Have you ever seen the night sky change? It does -- sometimes in beautiful and unexpected ways. To see it, though, usually requires patience. The above award winning video shows several of the possible changes in dramatic fashion with a time lapse video. Visible are sunset-illuminated clouds moving , stars of vivid colors rising , the long tail of a Comet Lovejoy rising, bright satellites crossing , a meteor exploding , a distant lightning storm approaching , skyscapes including the Magellanic Clouds rotating, and a fisheye sky rotating while the foreground becomes illuminated by moonlight. Frequently featuring an artistic human sculpture in the foreground and the southern sky in the background, the video closes with a time lapse clip of a total lunar eclipse . If you can identify any more of the sky events depicted -- or any of the landscapes shown -- please illuminate them with a comment .
