Titan’s Brew.

“‘Scientists previously thought that as we got closer to the surface of Titan, the moon’s atmospheric chemistry was basically inert and dull,’ said Murthy Gudipati, the paper’s lead author at JPL. ‘Our experiment shows that’s not true. The same kind of light that drives biological chemistry on Earth’s surface could also drive chemistry on Titan, even though Titan receives far less light from the sun and is much colder.'”

A NASA/JPL simulation of Titan’s atmosphere suggests a chaotic chemical brew conducive to life on Saturn’s most interesting moon. “Now we know that sunlight in the Titan lower atmosphere can kick-start more complex organic chemistry in liquids and solids rather than just in gases.” (Titan image via this 2011 post.)

That’s No Moon.

“[T]he detail is stunning in his original high-res version. You can see craters on Tethys, and the thick atmosphere enshrouding Titan (including the north polar haze cap). The image is very close to natural color, so this is approximately what you would see if you were there (shortly before freezing and asphyxiating, but what a way to go).“

Propaganda or no, a fully-armed and operational battle station would seem to be approaching Saturn’s moon of Titan in this breathtaking image by Gordan Ugarkovic, taken from data by the Cassini spacecraft. “Spacecraft and observatories store their images on hard drives, and anyone with access and the knowledge of how to process that data — no simple task, I assure you! — can use it to do their own work.“

Cosmic Data.

“Fact:…The density of Saturn is so low that if you were to put it in a giant glass of water it would float.” And another pilfered link, which I meant to post last week: Megg of Quiddity points the way to 10 Cool Facts about Space (although, to paraphrase The Smiths, some facts are cooler than others.)

Eye on Enceladus.

“All these worlds are yours, except Europa…oh, and Enceladus.” In very big news, NASA announces that Cassini has found water plumes on Enceladus, Saturn’s moon. “This finding has substantially broadened the range of environments in the solar system that might support living organisms, and it doesn’t get any more significant than that…I’d say we’ve just hit the ball right out of the park.” What’s more, “unlike Europa, which researchers believe harbors a vast ocean beneath kilometers of thick ice, Enceladus’ water may be just below the surface.”

That’s no moon, it’s a…uh, a moon.

The Cassini discovers a new moon within Saturn’s rings. “Tentatively called S/2005 S1, the moon measures four miles across and is about 85,000 miles from the center of Saturn.” (Via Corsairs United.)

Titan A.E.

Score one for the ESA: The Huygens probe successfully lands on Titan and broadcasts images from the surface for five hours (a.k.a. much longer than expected.) (See, NASA? It’s much easier to pull these types of missions off when you don’t have to convert from standard to metric and back.) And now, for Europa… Update: 2020 Hindsight has done an exemplary job today of covering the details and implications of the landing.
