The international Cassini spacecraft has detected the faint but distinct signature of dust coming from outside our Solar System.

By comparing radar images of areas on Titan to those of Earth's deserts, scientists have identified two distinct types of sand dune on Saturn's largest moon – and discovered eroded structures that indicate that Titan's climate may have once been very different.

Saturn's moon Titan is home to seas and lakes filled with liquid hydrocarbons, but what makes the depressions they lie in? A new study suggests that the moon's surface dissolves in a similar process that creates sinkholes on Earth.

The scientific community is invited to submit proposals for participation to the Cassini-Huygens mission through the Participating Scientists programme. This Announcement of Opportunity is issued jointly by ESA, NASA, and ASI. A brief statement of work is due on 1 June 2015; the full proposal is due on 18 August 2015.

Static electricity is known to play an important role on the airless, dusty Moon, but evidence of surface charging on other objects in the Solar System has been elusive. However, a new analysis of data from the international Cassini mission has revealed that the orbiter was briefly bathed in a beam of electrons coming from the electrostatically...

The international Cassini mission has revealed that a giant, toxic cloud is hovering over the south pole of Saturn's largest moon, Titan, after the atmosphere has cooled in a dramatic fashion.

The international Cassini mission has revealed hundreds of hydrocarbon lakes and seas spread across the icy surface of Saturn's moon Titan, mostly in its polar regions. While most of the liquid in the lakes is thought to be replenished by rainfall from clouds in the moon's atmosphere, the cycling of liquid throughout Titan's crust and atmosphere...

The scientific community is invited to submit proposals for participation to the Cassini-Huygens mission through the Participating Scientists (PS) programme. This Announcement of Opportunity (AO) is issued jointly by ESA, NASA, and ASI. A brief statement of work is due on 28 July 2014; the full proposal is due on 26 September 2014.

Saturn's icy moon Enceladus has an underground sea of liquid water, according to the international Cassini spacecraft.

The NASA-ESA-ASI Cassini spacecraft has been observing the Saturn system, including the giant satellite Titan, for more than 9 years. A detailed analysis of Cassini data has now confirmed predictions that the density of Titan's ionosphere is directly linked to the 11 year cycle of solar activity.

Scientists have confirmed the presence of PAHs - Polycyclic Aromatic Hydrocarbons - in the upper atmosphere of Saturn's largest moon, Titan. After forming, PAHs grow into larger aggregates that drift down, eventually giving rise to aerosol particles in the haze layer that blankets Titan's surface. The study is based on data from the Cassini...

The scientific community is invited to submit proposals for Participating Scientists (PS) to the Cassini-Huygens mission. This Announcement of Opportunity is published jointly by ESA, NASA, and ASI. This year proposals are being taken via a two-step process. Step-1 proposals are required. The deadline for submission of Step-1 proposals is 26...

During an unusually strong blast of solar wind arriving at Saturn, the Cassini spacecraft detected particle acceleration to ultra-high energies, similar to what takes place around supernova explosions.

New observations made by the international Cassini spacecraft confirm that dramatic atmospheric reversal takes place as the seasons shift on Saturn's giant moon Titan.

A giant storm whirling on Saturn for the past two years has given planetary scientists new clues about the planet's atmosphere. The study is based on infrared observations from the Cassini orbiter and ground-based telescopes.

ESA's Huygens probe bounced, slid and wobbled its way to rest in the 10 seconds after touching down on Saturn's moon, Titan, in January 2005, a new analysis reveals. The findings provide novel insight into the nature of the moon's surface.

Cassini-Huygens has found large tides on Saturn's moon Titan, pointing to the existence of a liquid ocean - most likely composed of water - swirling around below the surface.

A region on Saturn's moon Titan has been found to be similar to the Etosha Pan in Namibia, Africa. Both are ephemeral lakes - large, shallow depressions that sometimes fill with liquid.
