OTD in Space – March 4: Jupiter's Rings Discovered
- last year
On March 4, 1979, NASA’s Voyager 1 spacecraft took the first photos of rings around Jupiter. [‘On This Day in Space’ Video Series on Space.com](https://www.space.com/39251-on-this-day-in-space.html)
This was the first time anyone had seen Jupiter’s rings. Because the rings are so thin and faint, it's extremely difficult to see them from Earth with ground-based telescopes. Even for a spacecraft out near Jupiter, the rings essentially invisible unless the cameras look at them edge-on or from an angle where sunlight shines directly through them. Since Voyager 1 first saw the rings, other space missions like Juno and Galileo have continued to study them. Scientists believe that the rings formed by comets colliding with Jupiter's moons and kicking dust into the planet's orbit.
