Rotate? The was that astronomers had been puzzling over for forty years was the Dutch astronomer Christian Huygens (HOY-genz, 1629-1695). He had built first person to understand what it a better telescope than anyone before him, so that he could see Saturn more clearly and with greater magnification than any- one before him. Using this telescope in 1656, he looked at Saturn's "handles" and decided that what he was looking at was a ring that encircled Saturn. Even if it turned around the planet, part of it would always project on either side of the planet, so that it would give the effect of motionless handles.
