The Galactic Radio Nebulae


With these words Chinese astronomers in the year 1054 AD recorded their observation of a new star in the constellation Taurus. Early in the morning of that same day, July 5, Plains Indians in the Western United States witnessed the appearance of this new star—an event so startling to them that they etched a record of it into the rocks. A pictograph found in Chaco Canyon, New Mexico, shows a star-like symbol, seldom used by those Indians, drawn next to a crescent (moon). The new star described by the Chinese astronomers, who had a long tradition of observing the heavens behind them, did indeed appear close to the crescent moon and it would have been visible in the early morning from the rocky overhang in Chaco Canyon.
