Saturn Stars in Three Hubble Movies
March 20, 2007
Photogenic Saturn has now become a movie star. 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. The images
were taken with Hubble's Wide Field and Planetary Camera
2 in 1995 and the Advanced Camera for Surveys in 2003
