Astronomers have woven NASA Hubble Space Telescope images of Saturn, its rings, and several of its moons into three movies. Each movie highlights unique times in the planet’s 30-year waltz around the Sun. Two of the movies show the motion of several of Saturn’s moons when the planet’s rings were tilted nearly edge-on to Earth and to the Sun.
These edge-on alignments of the rings occur roughly once every 15 years. Another movie presents a clear view of Saturn’s Southern Hemisphere when the planet’s rings were at maximum tilt toward Earth. Hubble snapped only about a dozen images during each of these three events, so astronomers created software to extend the photos into the hundreds of images needed for a movie.
