The day after Dave Crawford and I inspected nighttime Tucson, I drove five hundred and fifty miles north to Bryce Canyon National Park, in southern Utah. That evening, I joined about two hundred people, including many children, outside the visitors' center, where telescopes of various sizes had been set up in the parking lot. Several were equipped with computerized tracking devices, which could be programmed to find and follow interesting objects in the sky. At one station or another, I saw the four Galilean satellites of Jupiter (tiny dots in a line), Saturn (with rings), a dense group of old stars, known as a globular cluster, a pair of twin stars (one blue and one gold), and the mountains and valleys that Galileo saw on the moon. With just my own eyes, I saw the orbiting Hubble Space Telescope, which rapidly crossed the sky just before eleven o'clock, and, a little later, I saw the meteor-like flash of a passing Iridium satellite.
I spoke with Chad Moore, the program director of the National Park Service's Night Sky Team. "Many people who come to our programs have never really looked at the night sky," he told me. "A woman once came up to me and said, 'The moon was out during the day this morning -- is that O.K.?' "
I laughed out loud when I read that last sentence.
And for good measure in reference to Bruce Sterling's photos of a recent Texas fire, here are two of a 2009 fire at Bryce Canyon:
