Two hours after sunset comes the combined light of over a billion stars, all too distant to be seen individually by the human eye. The first star to appear may actually be a planet, but it is soon followed by Vega, Arcturus and other bright stars. Look quickly because this phenomenon is soon engulfed in darkness as the stars take the stage. This is the edge of Earth's own shadow being projected on to the atmosphere. After the last light of the setting sun fades from the highest clouds, suddenly a purple band will appear directly above the eastern horizon. Bryce is a phenomenal place for stargazing, but before planets and stars appear, look quickly for the rare sight of Earth's penumbra.
