Spitzer Space Telescope Used To Find Saturn’s New Ring
Astronomers using NASA’s Spitzer Space Telescope discovered a new ring around Saturn. The ring is too diffuse to reflect sunlight and cannot be seen with the naked eye. The particles that compose the ring are visible using infrared light, light that Spitzer can see. The newly discovered ring, which is associated with the moon Phoebe, stretches roughly 12.5 million kilometers from Saturn, if not further. For comparison, the outer bound of Saturn’s next largest known ring, the E ring, is less than half a million kilometers from Saturn. For more information, see Discovery.
