This awe-inspiring collection of photographs gives those of us stuck on Earth a glimpse of what our home planet looks like from the window of a space craft... and the big blue marble has never looked more beautiful. All the continents are shown, as well as weather events, the Aurora borealis, and the visible effects of anthropogenic environmental change--deforestation and desertification chief among them. Take a sobering look at our lovely planet and realize how small and fragile it really is. [via]
