Another smoking gun in the search for life in Enceladus’ ocean

Franck Marchis • April 13, 2017

NASA's Cassini spacecraft sniffed out molecular hydrogen spewing from Enceladus' subsurface ocean. The discovery means Saturn's moon has all the basic ingredients needed to support life.

Cassini, with only a half-year to go at Saturn, just keeps dropping awesome images

Jason Davis • March 09, 2017

Our latest roundup of Cassini goodies from Saturn includes Pan, a ravioli-shaped moon that orbits inside the planet's ring system.

Explorer of Enceladus and Titan

Van Kane • February 01, 2017

For the third time in less than a decade, scientists have proposed a multiple-flyby mission to explore the habitability of Saturn’s ocean moons Titan and Enceladus.

Amazing photos of tiny moons as Cassini orbits among the rings

Emily Lakdawalla • January 19, 2017

Behold: Daphnis, the tiny, 8-kilometer moon that orbits within a ring gap, gently tugging on the edges of the gap to create delicate scallops.

Serene Saturn (or the “Glutton for Punishment” mosaic)

Ian Regan • November 08, 2016

A week ago Saturday I decided -- against my better judgment -- to tackle this monster of a mosaic. I call it the "Glutton for Punishment" mosaic.

Cassini's camera views of Titan's polar lakes in summer, processed into pseudocolor

Emily Lakdawalla • September 12, 2016

Titan's north polar lakes are well-lit by summer sun in these recent Cassini images. Image processing enthusiast Ian Regan shares his recipe for processing the longer-wavelength Titan images into visually pleasing "pseudocolor."

New work with 35-year-old data: Voyagers at Ganymede and Saturn

Emily Lakdawalla • May 25, 2016

The what-o-sphere? An explainer

Anna Scott • May 05, 2016

Why do we need to slice up atmospheres into classifications like the troposphere, stratosphere, mesosphere, and thermosphere?

Atmospheric Waves Awareness: An Explainer

Anna Scott • April 20, 2016

There are two types of atmospheric waves that are critically important on Earth and other planets: gravity waves and planetary waves.

Fog Detection from the Surface of Titan: New Findings From Old Data

Brittney Cooper and Christina Smith and John Moores • April 07, 2016

Huygens may have landed on Titan over a decade ago, but a group of researchers from York University were able to make a new and unexpected discovery with this older dataset.
