HONG KONG: Saturn has the most magnificent set of rings of any planet in the Solar System. This network of thousands of ringlets are separated by gaps, the largest of which is the Cassini Division.
Astronomers have now found that the largest of Saturn’s rings is significantly larger than once believed, stretching for 7,000 times the diameter of the planet itself.
The Phoebe ring surrounding Saturn was discovered by astronomers using the Spitzer Space Telescope, who noticed the massive structure in infrared data. New examination, using the Wide-field Infrared Survey Explorer, reveals this feature is composed of dust, reaching to between 3.75 and 10 million miles away from its parent planet. Initial estimates placed the size of the Phoebe Ring between 4.8 and 7.7 million miles. Here, the dust is heated by energy from the distant sun, causing the material in glow in infrared wavelengths seen by astronomers.
