Phosphorous detection strengthens case for Enceladus’ habitability

16 June 2023 Astronomy Now

Researchers find high concentrations of phosphorous in water ice spewed from Saturn’s moon Enceladus, more evidence of a habitable sub-surface environment.

Infrared map of Enceladus shows “tiger stripes” and hints of recent resurfacing

22 September 2020 Astronomy Now

Researchers using data from the Cassini mission have put together a new global spectral map of Enceladus, a moon with icy jets spewing into space from a sub-surface ocean.

Analysis indicates Enceladus’ sub-surface ocean may be habitable

28 January 2020 Astronomy Now

A new analysis incorporating data from the Cassini mission suggests Saturn’s icy moon Enceladus may host a habitable environment in its sub-surface ocean.

Cassini mosaic captures moon sculpting Saturn’s rings

14 June 2019 Astronomy Now

Data collected by the Cassini spacecraft before its 2017 demise continues to shed light on the composition and dynamics of Saturn’s rings.

Viewed from Saturn, nearest stellar neighbors offer compelling target

21 May 2018 Astronomy Now

Viewed from Saturn, Earth’s nearest stellar neighbors, the trinary Alpha Centauri system, offer a compelling view as they pass just above the ringed planet’s cloudtops in a 2008 occultation experiment to learn more about Saturn’s atmosphere.

A planet, its rings and three moons – a postcard from Cassini

8 May 2018 William Harwood

A postcard from Cassini – a stunning edge-on view of Saturn, its rings, their shadow and three moons, captured by the orbiter in 2006 as it passed within about 2.7 million kilometres (1.7 million miles) of the sixth planet.

Cassini’s view of Saturn’s rings still dazzling

1 May 2018 Astronomy Now

NASA’s Cassini spacecraft plunged into the atmosphere of Saturn in 2017, concluding a hugely successful mission to explore the planet, its rings and icy moons. The spacecraft’s close-up images of Saturn’s ring system likely will remain unmatched for decades to come.

Saturn’s past and present moons

12 April 2016 Astronomy Now

Saturn’s beautiful rings form a striking feature, cutting across this image of two of the planet’s most intriguing moons: Titan (diameter, 3,200 miles) and Enceladus (313 miles). The rings have been a source of mystery since their discovery in 1610 by Galileo Galilei, but there is not full agreement on how they formed.

Bright impact basin on Saturn’s icy moon Tethys

28 July 2015 Astronomy Now

In this NASA/ESA Cassini mission image of Saturn’s 660-mile-wide moon Tethys, the giant impact basin Odysseus stands out brightly from the rest of the illuminated icy crescent. Some 280 miles across, Odysseus is one of the largest impact craters on Saturn’s icy moons, and may have significantly altered the geologic history of Tethys.

Triple crescents

22 June 2015 Astronomy Now

A single crescent moon is a familiar sight in Earth’s sky, but with Saturn’s many moons, you can see three or even more. Rhea (top), Titan and Mimas (bottom) align for this image from NASA’s ongoing Cassini mission.
