Astrobiology Roundup: Planets, Moons, and Stinky Comets

707154main_astrobiology

Scientific discoveries across all fields just keep coming and coming. Here’s a small assortment of goodies from the past couple of weeks. How do you form planets around stars in triple systems? You feed them of course. New data from the Atacama Large Millimeter/submillimeter Array (ALMA) telescope in northern Chile has probed the gas and [...]

Summer Shorts: 101 Geysers Point To Enceladus’ Deep Ocean

It’s summer in the northern hemisphere of a small, damp, planet orbiting a middle-aged star in a spiral galaxy of matter enjoying a brief heyday before colliding with another galaxy in some 4 billion orbits of the same small, damp, planet. Time for some brief stories. The NASA/ESA Cassini mission to Saturn first spied plumes [...]

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

The original pale blue dot - Earth from 3.7 billion miles away (NASA/JPL/Voyager)

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, [...]

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 [...]

Exo-cornucopia

Watch out! There's a lot of stuff up there...

  This has been an extraordinary week for planets (moons), exoplanets, and astrobiology. I’m hard pushed to write properly about all these things but sometimes the sheer tidal mass of discoveries tells its own story.       And tidal masses is the first one up. This week new results from the Cassini mission around [...]

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 [...]

Water from a Saturnian Moon Rains Down on the Ringed Planet

Enceladus water jets

Enceladus, a small satellite of Saturn, has captivated planetary scientists for years with its watery polar geysers and ridgelike surface features known as "tiger stripes." Now it has a new layer of intrigue. The gas and ice escaping from Enceladus and shooting out from the moon’s south pole in towering jets, which fill Saturn’s diffuse [...]

Something slammed into the rings of Saturn and Jupiter

PASADENA—This week I’m here at the annual Division for Planetary Sciences meeting. Much as I enjoy Pasadena, it’s rather a comedown from last year’s meeting place in Puerto Rico. Leave aside the natural attractions: even the freeways in Puerto Rico are in better repair than California’s. Then again, we don’t come here for the earthly [...]

“In Saturn’s Rings” Movie Trailer

In Saturn's Rings

If you love the programs at planetariums or the sci-fi films where you are visually propelled through the expanses of space, prepare yourself for a film specifically designed for the giant screen that explores the planet Saturn using only scientific photographs, primarily from the Cassini-Huygens mission, among others, stitched together and animated to full motion [...]
