摘要

For centuries after Galileo used his telescope to view its rings, Saturn was known to be the only planet of the solar system to have a coterie of rings till space probes discovered rings around Jupiter, Uranus and Neptune. But a recent discovery of a massive invisible ring around the planet again puts Saturn in the forefront. The ring is really huge - ranging in diameter from 14 million to 25 million kilometres and is about 10 times bigger than the planet's previously largest known ring, the E ring. (Saturn's diameter is 116,464 kilometres). The ring is not visible in optical telescopes because it emits only in infrared wavelengths. The ring was discovered by Anne Verbiscer and Michael Skrutskie of the University of Virginia and Douglas Hamilton of the University of Maryland in 2009 from data sent back by NASA's Spitzer Space Telescope, which imaged the ring in infrared, but only now has its real nature been deciphered. The Spitzer findings have been corroborated by data from NASA's Wide-field Infrared Survey Explorer (WISE) telescope (Nature, 11 June 2015 | doi: 10.1038ature14476).
