A Naked Titan Revealed by 13 Years of Cassini Data

Saturn’s largest moon Titan boasts the distinction of being the only moon in the solar system to have a thick atmosphere…so thick, in fact, that its surface is perpetually hidden from our view—but not from the view of the Cassini spacecraft’s infrared cameras! Cassini, now over ten months gone after its Sept. 2017 plunge into…

This Toxic Compound on Titan Could Support Life “Not as We Know It”

Saturn’s largest moon Titan is often called an analogy to early Earth, with its thick, chemical-rich atmosphere and widespread system of flowing rivers and north polar lakes. But located almost a billion miles away from the Sun, everything on Titan is shifted into a completely different—and frigid—level of existence from that found on Earth. With…

Titan’s Cold Hydrocarbon Lakes Could Be Naturally Carbonated—Er, Nitrogenated

At the north pole of Saturn’s largest moon Titan lie the largest (and only known) bodies of surface liquid in the Solar System outside of Earth. But on Titan, where temperatures are regularly around negative 300ºF, the liquid isn’t water but rather methane and ethane: compounds which are found as gases here on Earth. Titan’s seas and lakes are…

Revisit Our First (and Only) Landing on Titan

When you think of spacecraft landings on other worlds, you probably first think of Mars, the Moon, Venus, and comet 67P (if you’ve been following along over the past couple of years.) But—in addition to the asteroid Eros and hard impacts on a comet and Mercury—Saturn’s moon Titan was also visited by an alien (i.e.,…

Bright Clouds Make a Comeback on Titan’s North Pole

Floating high above Titan’s hydrocarbon lakes, wispy clouds have finally started to return to the moon’s northern latitudes…but in much less numbers than expected. Models of Titan’s climate have predicted more cloud activity during early northern summer than what Cassini has observed so far, suggesting that the current understanding of the giant moon’s changing seasons is…

This is What it Would Look Like to Fight Flying Dragons on Titan

Obviously this is a totally-for-fun sci-fi video, but what a video! Created by Oscar-nominated Irish filmmaker Ruairi Robinson, it shows fleets of very industrial-looking fighter skiffs hunting giant flying eels through the skies of some very cloudy planet… the first thought that came to my mind was Titan! (Although Titan is more hazy than cloudy…

Despeckled Radar Images Give a Clearer View of Titan’s Shores

At 1,600 miles (2,576 km) across Titan is by far Saturn’s largest moon – in fact it’s the second-largest satellite in the solar system. It’s also the only world besides Earth where liquids have been found in large amounts on the surface, in the form of lakes and streams of frigid methane and ethane. This makes Titan…

Remembering Huygens’ Titan Landing, Ten Years Later

This incredible image was captured ten years ago today, on January 14, 2005. It shows the murky surface of Saturn’s moon Titan as seen by the European Space Agency’s Huygens probe after it made its historic descent through the moon’s thick haze and clouds and landed in a frozen plain of crusty methane mud and icy pebbles….

Saturn and Titan Show Off Their Crescents

It may not be in color but that doesn’t make it any less beautiful: this stunning image from Cassini shows Saturn and its largest moon Titan – the second-largest moon in our solar system, after Jupiter’s Ganymede – from their night sides, both showing their crescents against the blackness of space. Titan’s crescent nearly wraps all…

Cassini Spots the Sun Shining on Titan’s Sea

There’s nothing like the beautiful reflection of sunlight off the mirrored surface of a lovely lake… regardless if you’re on Earth or Saturn’s moon Titan! This picture, a mosaic of images acquired by Cassini’s Visual Infrared and Mapping Spectrometer (VIMS) instrument during a flyby on August 21, 2014, shows exactly that: sunglint reflecting off the super-smooth…

Cassini Watches Clouds Form Over Titan’s Methane Sea

What’s the weather forecast on Titan? Well if you’re planning a vacation down by the shores of Ligeia Mare you may get some cloudy skies, if what happened at the end of July repeats itself! The animation above was made from images acquired by Cassini during a flyby of Titan in July 2014, showing the…

Cassini Marks Ten Discovery-Filled Years at Saturn

Just a week after Curiosity celebrated its first Martian year in Gale Crater and we have yet another milestone anniversary in Solar System exploration: as of 10:48 p.m. EDT tonight Cassini will have been in orbit around Saturn for a full decade! “There are times when human language is inadequate, when emotions choke the mind, when the magnitude…
