The drive to map the sky is as old as civilization itself. The Great Pyramids in Egypt point straight at specific stars. The ancient stone configuration Stonehenge in Britain is arranged to track the progress of the sun toward its northernmost point in the sky. The first astronomical observatories date back as early as the third century in the Middle East; at that time, astronomy was mixed up with astrology, and sky-watchers used cosmic measurements to predict the future. Since Islamic law forbids such superstition, many of the earliest astronomers were executed for heresy.
