You can find many cool pictures, including the earthlights picture at -

They refeature the earthlights pic every now and then. They change the dates but I don't think it's an updated picture. It was just the picture of the day a couple days ago, but the date on the photo itself was Aug 11, 2002, which is the last time it was the photo of the day. So, I think they may just be refeaturing it, rather than putting up a new version. I'd like to see a new version, though, to compare how the lights may have changed over time.
