Water Erupts Across the Solar System

Reading the scientific headlines recently one would be forgiven for thinking that we’re experiencing a bout of interplanetary gastrointestinal distress. First, Saturn’s diminutive moon Enceladus continues to spew what we think are giant sprays of salty water from gnarled creases in its southern icy surface – captured in glorious imagery by the Cassini spacecraft over [...]

Earth Waves To Saturn: The Pictures

IMG004880-br500

Sometimes a picture really is worth a thousand words, or in this case 1,400 pictures are worth a few words. Here is the collage of images uploaded by people across the planet for NASA’s Cassini ‘Wave at Saturn’ event on July 19th 2013, while Cassini snapped Earth in turn, as a teeny, tiny dot of [...]

Return To The Pale Blue Dot

One of the most enduring and captivating images from our exploration of space in the late 20th century was Voyager 1′s mosaic of our own solar system – a family portrait from 3.7 billion miles away. Captured in these shots was a faint speck of bluish light, in one single pixel of Voyager’s digital camera, [...]

A Jupiter Carousel: Hotspots Ride The Wave

Jupiter seen by Cassini (NASA)

New analysis of data taken by the Cassini mission during its encounter with Jupiter in 2000 reveal that exceptionally clear atmospheric ‘hotspots’ effectively ride up and down in the Jovian skies as they are formed by what’s known as a Rossby wave – a phenomenon familiar to us here on Earth. The authors of the [...]

The Vortex

Northern polar view (NASA/Cassini)

This is simply too good to pass up, although it’s been doing the rounds online. As the seasons change on Saturn the north polar region is now getting its share of faint solar illumination. Cassini recently (very recently, as in Nov 27th) took this amazing image of the swirling atmospheric circulation at the northern pole [...]

Saturn Is Alive, No CGI

Janus above Saturn (NASA/Cassini)

It seems that the Saturnian system just keeps on giving when it comes to amazing imagery. Of course it helps to have a $3 billion space mission in place like Cassini to record everything going on. From Saturn The Movie, to The Austere Beauty Of Other Worlds, and Raw Footage From An Alien World, I’ve [...]

Raw Footage From An Alien World

Swinging around, Enceladus against a backdrop of noise and what may be stars (Cassini raw image)

Have you ever wondered what it would really be like for a person to journey to a truly distant and alien place; another planet, even another planetary system? What kind of things would we first see through our windows, or our cameras? What would our sensory experience be in such a distant realm? Would we [...]

The Austere Beauty of Other Worlds

Magnificent Saturn, subtle blue and gold tones, while its moon Dione circles in silence (NASA/JPL)

In the northern winter months we are surrounded by the stark beauty of chilled landscapes. From the darkness of the far north, broken perhaps only by starlight and the glow of aurora, to the brisk grey streets of Manhattan and its now skeletal trees with their claw-like limbs and knobbly stubs pressed to the skies, [...]

Saturn, the movie

Saturn post equinox

This extraordinary excerpt is from an upcoming Imax movie that uses Cassini orbiter imagery (NO computer generated images) to create some stunning flybys and flythroughs of the Saturnian system. Cassini has taken so many high-res pictures that this stitched together footage is possible. All I can say is “wow”. We truly are a species that [...]

This Video Montage of Saturn’s Rings and Moons Is Simply Gorgeous [Video]

For more than nine years, NASA’s Cassini probe has orbited Saturn, examining its rings and moons in unprecedented detail and sending back images of things and places humans had never seen. Filmmaker Fabio di Donato has managed to collapse that discovery and wonder into four minutes. In a new film posted on Vimeo, di Donato [...]

Cassini Spacecraft Takes 1 Last Look at Home Today

Photo credit: CICLOPS, JPL, ESA, NASA

For a quarter-hour today, some of us on Earth can look up and know that almost a billion miles away, above the sky, a set of robotic eyes is looking right back. The Cassini spacecraft will be passing into Saturn’s shadow at that time, slewing its cameras to catch the planet’s majestic rings backlit by [...]

Cassini Spacecraft Reveals Unprecedented Saturn Storm

Saturn storm, 2011

Just as regions of our planet have monsoon season, or tornado season, so too does Saturn have its own stormy season. Once every Saturn year or so—which corresponds to roughly 30 Earth years—a giant, churning storm works its way through the clouds of Saturn’s northern hemisphere, sometimes encircling the entire planet like a belt. Lasting [...]

What caused Saturn to lurch? Second dispatch from the annual planets meeting

Rings of Saturn

FAJARDO, Puerto Rico—I first heard about Matt Hedman’s talk while going out to dinner on Tuesday night. Best talk of the meeting, I was told. Everywhere I went yesterday, I kept hearing about this guy Matt Hedman. A former professor of mine chided me for missing his presentation. The problem with the Division for Planetary [...]
