Saturn’s rings, composed of dust and ice, are remnants of earlier planetesimals that catastrophically broke up as they entered Saturn’s gravitational field. Microscopic dust particles in the rings are electrically […]
Several aspects of Saturn and its famous ring system have defied explanation. First, Saturn’s obliquity (the angle between its rotational and orbital axis) has a relatively large value of 26.7 […]
In 2017, the Cassini spacecraft ended its thirteen-year tenure at Saturn by plunging into its atmosphere. The close observations of Saturn’s magnetic field made during the Cassini Grand Finale orbits […]
On the surface of Titan—Saturn’s largest moon and the solar system’s second-largest natural satellite—volatiles are actively cycled in a way much like the hydrological cycle on Earth. Apart from Earth, […]
The gas giants of our solar system are so far from the Sun that they should have cold atmospheres. However, the upper atmosphere of Saturn (and the other gas giants) […]
Prior to Cassini’s Grand Finale, our knowledge of the vertical distribution of Saturn’s ionospheric electron densities relied upon the remote observations using radio occultation measurements. For the first time in the […]
Recently announced observations have discovered 12 new moons orbiting the biggest planet in our solar system. These moons range in size from 1 km (0.6 miles) to 3 km (1.9 […]
Cassini Science Symposium-Aug 12-17 2018 Poster Dear colleagues, Abstracts are due 16 April 2018 for the final Cassini Science Symposium. Please use the template provided on the website. Hosted by the […]
The Center for Space Physics at Boston University invites applications for a postdoctoral researcher position supervised by Professor Paul Withers. The research will involve the analysis of radio occultation observations of the ionospheres […]
NASA’s Cassini spacecraft has begun transmitting its latest images of Saturn’s icy, geologically active moon Enceladus, acquired during the dramatic Oct. 28 flyby in which the probe passed about 30 […]
The long-standing mystery of why Saturn seethes with enormous storms every 30 years may have been solved by scientists working with data from NASA’s Cassini mission. The tempests, which can […]
NASA’s Cassini spacecraft has provided scientists the first clear evidence that Saturn’s moon Enceladus exhibits signs of present-day hydrothermal activity which may resemble that seen in the deep oceans on […]
During 10 years of discovery, NASA’s Cassini spacecraft has pulled back the smoggy veil that obscures the surface of Titan, Saturn’s largest moon. Cassini’s radar instrument has mapped almost half […]
Researchers studying data from NASA’s Cassini mission have observed that Saturn’s largest moon, Titan, behaves much like Venus, Mars or a comet when exposed to the raw power of the […]
Ten years ago, an explorer from Earth parachuted into the haze of an alien moon toward an uncertain fate. After a gentle descent lasting more than two hours, it landed […]
NASA scientists have identified an unexpected high-altitude methane ice cloud on Saturn’s moon Titan that is similar to exotic clouds found far above Earth’s poles. This lofty cloud, imaged by […]
Scientists analyzing data from NASA’s Cassini mission have discovered that a giant, toxic cloud is hovering over the south pole of Saturn’s largest moon, Titan, after the atmosphere there cooled […]
NASA’s Cassini spacecraft will execute the largest planned maneuver of the spacecraft’s remaining mission on Saturday, Aug. 9. The maneuver will target Cassini toward an Aug. 21 encounter with Saturn’s […]
AGU Fall Meeting December 15-19, 2014 San Francisco, CA Abstract submission deadline: August 6, 2014 We solicit new research findings about the ionospheres, atmospheres and deep interiors of Jupiter, Saturn, […]
A combined NASA and European Space Agency (ESA)-funded study has found firm evidence that nitrogen in the atmosphere of Saturn’s moon Titan originated in conditions similar to the cold birthplace […]
