Making sense of Saturn's impossible rotation

Saturn may be doing a little electromagnetic shimmy and twist which has been throwing off attempts by scientists to determine how long it takes for the planet to rotate on its axis, according to a new study.

Image: Dione and Rhea appear as one

Sometimes it's all about perspective. This very convincing image of a conjoined moon masquerading as a snowman is actually two separate Saturnian moons – Dione and Rhea – taken from such an angle by the international ...

Image: Veil of ice in Saturn's rings

Saturn's rings, made of countless icy particles, form a translucent veil in this view from NASA's Cassini spacecraft.

Astronomers bid farewell to $3.9 bn Saturn spacecraft

Astronomers around the world bid farewell Friday to NASA's famed Cassini spacecraft, which launched 20 years ago to circle Saturn and transformed the way we think about life elsewhere in the solar system.

How two ground-based telescopes support NASA's Cassini mission

When NASA's Cassini spacecraft plunges into the atmosphere of Saturn on Sept. 15, ending its 20 years of exploration, astronomers will observe the giant planet from Earth, giving context to Cassini's final measurements.

Image: Haze on the Saturn horizon

This false-color view from NASA's Cassini spacecraft gazes toward the rings beyond Saturn's sunlit horizon. Along the limb (the planet's edge) at left can be seen a thin, detached haze. This haze vanishes toward the right ...

Image: Listening for Cassini

ESA's sensitive tracking antennas at New Norcia, Western Australia, and Malargüe, Argentina (seen here in 2012), are being called in to help gather crucial science data during Cassini's last months in orbit, dubbed the Grand ...

Catching Cassini's call

This week, ESA deep-space radio dishes on two continents are listening for signals from the international Cassini spacecraft, now on its final tour of Saturn.

IMAGE: The longest call

On 10 August 2016, ESA's tracking station at New Norcia, Western Australia, hosting a 35 m-diameter, 630-tonne deep-space antenna, received signals transmitted by NASA's Cassini orbiter at Saturn, through 1.44 billion km ...
