Cassini Mission Highlight: Mile-High Spikes Along Saturn’s B Ring

Icy particles along Saturn’s B ring rise dramatically in mile-high spikes, seen by Cassini in August 2009. (NASA/JPL-Caltech/SSI) A field of spike-like structures rise up over two miles from the outer edge of Saturn’s B ring in the amazing image above, captured by Cassini during Saturn’s spring equinox in August 2009. These pointy perturbations are caused by…

There’s a Cerulean Storm Swirling on Saturn’s North Pole

Like some giant beast’s great blue eye Saturn’s north polar vortex appears to glare up at Cassini’s wide-angle camera in this image, a color-composite made from raw images acquired in red, green, and blue visible light wavelengths on February 13, 2017.

Share Your Love of Cassini and Saturn with the World

Even if you’re feeling inundated by Valentine-themed everything at the moment, if you love space and you’re at all creative you’re definitely going to adore this. With Cassini in the final months of its 13 years at Saturn, NASA wants you to share your love of the spacecraft, its discoveries, and the ringed planet and its fascinating…

Intricate Details of Saturn’s Rings Are Revealed in Latest Cassini Images

Like those fractal designs that were so popular in the ’90s Saturn’s rings reveal finer and finer structures the nearer Cassini gets, now in the final year of its mission. Recent images from the spacecraft, captured in December 2016, show groove-like density waves and skyscraper-sized clumps within the planet’s icy rings—and it’s just a hint at what…

Watch Saturn’s Moons Race Inside the Rings

Round and round they go… the animation above, made from 14 raw images taken by NASA’s Cassini spacecraft on August 23, 2016, shows the moons Prometheus and Atlas orbiting Saturn within the Roche Division gap between its A (top right) and F (center) rings. The gravitational tug of Prometheus (92 miles / 148 km long) is strong…

Bend It Like Saturn

The lines of Saturn’s rings appear to get sharply bent as their reflected light passes through the upper atmosphere of the planet before being captured by Cassini’s camera in this raw image, acquired on June 9, 2016. Enormous Saturn of course is, by volume, nearly all atmosphere with a solid core only about the size…

Watch Incredible High-Speed Footage of the Apollo 11 Saturn V Liftoff

The Saturn V line of heavy launch vehicles used for NASA’s Apollo program were to this day the most powerful rockets ever used, and this video shows an intimate on-pad view of the ignition and liftoff of the one that carried Apollo 11 into space on July 16, 1969. Captured at 500 frames per second, the…

Dawn Finds Similarities Between Ceres and Saturn’s Moons

Around 600 miles wide, covered in craters and cliffs, a composition of rock and water ice… these are descriptions of both several of Saturn’s moons and the dwarf planet Ceres, based on recent observations by NASA’s Dawn spacecraft. New topographical maps show that, in terms of surface features anyway, Ceres shares similarities with Saturn’s icy…

Icy Tendrils in Saturn’s E Ring Traced Back to Enceladus

As the ice-encrusted moon Enceladus makes it way along its orbit around Saturn it gets repeatedly squeezed by the giant planet’s gravity, like a frozen stress ball with water-filled insides. This constant squeezing and relaxing generates friction heat in the moon’s crust, which could be responsible for keeping some of its internal water liquid and spraying…
