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.

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 ...

Cassini image: Criss-crossed rings

At first glance, Saturn's rings appear to be intersecting themselves in an impossible way. In actuality, this view from NASA's Cassini spacecraft shows the rings in front of the planet, upon which the shadow of the rings ...

Climate of Jupiter and Saturn may yield clues to Earth's weather

What can the climates of other planets tell us about the Earth's weather? According to a researcher at the University of Houston, data being collected from Jupiter, Saturn and Saturn's largest moon, Titan, can offer clues ...

Image: Dark pools on Titan

This radar image from the Cassini orbiter shows a thin strip of surface on Saturn's moon Titan. The yellow-hued terrain appears to be peppered with blue-tinted lakes and seas. However, these would not be much fun to splash ...

Image: Prometheus up close

NASA's Cassini spacecraft spied details on the pockmarked surface of Saturn's moon Prometheus (86 kilometers, or 53 miles across) during a moderately close flyby on Dec. 6, 2015. This is one of Cassini's highest resolution ...
