Today’s APOD is extra stunning, don’t you think? In one of those perfectly-timed shots, it almost appears as if the arc of the Milky Way is rising out of Silex Springs in Yellowstone National Park, United States.
Not only does Yellowstone look like a different planet, it holds interest for scientists studying different planets. Astrobiologists conduct research in the extreme environments of Yellowstone’s unique geological features. Fascinating new species of extremophiles have been discovered there, including a bacterium that creates energy from light.
