James Webb telescope observes the rings of Chariklo with a high-precision occultation technique
In 2013, an international science team watched as Chariklo, a minor planet between Saturn and Uranus, passed in front of a background star, a technique known as occultation. Remarkably, the star blinked twice before and after disappearing behind Chariklo, revealing the presence of two thin, dense rings, the first ever detected around a Solar System object other than a giant planet. The rings have now been observed by the James Webb Space Telescope (JWST), in its first observed stellar occultation.
