Galileo Discovers Origin of Jupiter's Rings
News story originally written on September 21, 1998

Scientists discovered how Jupiter's rings were made. Jupiter's rings are made up of dust and other small particles. This dust and other space junk was thrown off of the small moons surrounding Jupiter when these moons were struck by comets or asteroids.

You can look at the picture to the left to see what Jupiter's rings look like. Can you redraw the picture at home?
