If You Were Wondering What Earth Looks Like From Saturn, Here You Go

That’s here; that’s home; that’s us. The image above shows what Earth looked like to NASA’s Cassini spacecraft on April 13, 2017 as it flew past Saturn’s night-shadowed A and F rings. At the time the raw images were captured Saturn and Cassini were about 889.6 million miles (1.43 billion kilometers) from Earth. From that distance…

Saturn’s Moon Atlas is Literally a Flying Saucer

If you thought Pan resembled a UFO, Atlas is even more saucer-shaped! Slightly larger at about 19 miles across, Saturn’s moon Atlas was passed by NASA’s Cassini spacecraft on April 12, 2017, coming within about 9,000 miles. The images above are a collection of eight from Cassini’s closest approach. Like its smaller sibling Pan, Atlas…

Iapetus: Saturn’s Stained Moon

Saturn’s “yin-yang” moon Iapetus (pronounced eye-AH-pe-tus) is seen in this image, a color composite made from raw images acquired by Cassini’s narrow-angle camera on March 11, 2017. The color difference on Iapetus is due to a fine coating of dark material that falls onto its leading hemisphere, sent its way by the distant moon Phoebe traveling within the recently-discovered giant diffuse…

Our Best Ever Look at Pan, Saturn’s Little “UFO”

Behold the almighty Pan! Thanks to Cassini’s ring-grazing orbits we’ve just received the highest-resolution images ever of Pan—which, at only about 17 miles (27 km) across admittedly isn’t very “almighty” but its flying saucer-like shape is really quite fascinating! The raw images above were acquired by Cassini on March 7, 2017 and received on Earth on…

Look Into The Dark Eye of Saturn’s Southern Storm

I know I said in my previous post that the Solar System is not a vortex (and it’s not) but that doesn’t mean there are no vortexes in the Solar System—in fact, thanks to the churning atmospheres of the gas giants, it’s full of them! And that’s no better demonstrated than at the poles of…

Cassini Pinpoints a Propeller in Saturn’s Rings

NASA’s Cassini spacecraft captured these images of a propeller in Saturn’s A ring on Feb. 21, 2017. These are the sharpest images ever taken of a propeller and reveal an unprecedented level of detail. This propeller is nicknamed “Santos-Dumont” after the Brazilian-French aviator who is hailed as the father of aviation in Brazil. The February 2017 imaging…

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

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 the gravitational nudges of tiny (~1/2 mile) embedded moonlets traveling around Saturn within the B ring, causing fine icy…

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…
