Mystery Feature Evolves in Titan’s Ligeia Mare

These images from the Radar instrument aboard NASA’s Cassini spacecraft show the evolution of a transient feature in the large hydrocarbon sea named Ligeia Mare on Saturn’s moon Titan. Analysis by Cassini scientists indicates that the bright features, informally known as the “magic island,” are a phenomenon that changes over time….

Saturn the Mighty

It is easy to forget just how large Saturn is, at around 10 times the diameter of Earth. And with a diameter of about 72,400 miles (116,500 kilometers), the planet simply dwarfs its retinue of moons. One of those satellites, Tethys (660 miles or 1,062 kilometers across), is seen here…

35th Anniversary of the Voyager 1 Saturn Flyby

On November 12, 1980, 35 years ago, Voyager 1 became the second spacecraft to flyby Saturn. Its main objectives were to conduct close-up studies of Jupiter and Saturn, Saturn’s rings, and the larger moons of the two planets. Built to last 5 years, the spacecraft is in interstellar space today…

NASA’s Cassini Finds Monstrous Ice Cloud in Titan’s South Polar Region

New observations made near the south pole of Titan by NASA’s Cassini spacecraft add to the evidence that winter comes in like a lion on this moon of Saturn. Scientists have detected a monstrous new cloud of frozen compounds in the moon’s low- to mid-stratosphere – a stable atmospheric region…

Cassini Finds Global Ocean in Saturn’s Moon Enceladus

A global ocean lies beneath the icy crust of Saturn’s geologically active moon Enceladus, according to new research using data from NASA’s Cassini mission. Researchers found the magnitude of the moon’s very slight wobble, as it orbits Saturn, can only be accounted for if its outer ice shell is not…
