Titan Globe, a mosaic of infrared images with nomenclature, Photo of infrared specular reflection off, Contrasting images of the number of lakes in Titan's northern hemisphere (left) and southern hemisphere (right), Two images of Titan's southern hemisphere acquired one year apart, showing changes in south polar lakes. Titan's atmosphere is about 1.19 times as massive as Earth's overall,[25] or about 7.3 times more massive on a per surface area basis. [41] Titan has been around since the Solar System's formation, but its surface is much younger, between 100 million and 1 billion years old. Radar observed several circular features that may be craters in the bright region Xanadu during Cassini's April 30, 2006 flyby of Titan. [111][112] The major difference with the TiME probe would be a propulsion system. One of the legends of the Nine states that they are ancient leviathan intelligences originating from either Europa or Titan.

Observations of the atmosphere, made in 2004 by Cassini, suggest that Titan is a "super rotator", like Venus, with an atmosphere that rotates much faster than its surface. [104] The two rocks just below the middle of the image on the right are smaller than they may appear: the left-hand one is 15 centimeters across, and the one in the center is 4 centimeters across, at a distance of about 85 centimeters from Huygens. The deduction of an atmosphere by Kuiper in the 1940s was the next major observational event.

Huygens landed[100] on Titan on January 14, 2005, discovering that many of the moon's surface features seem to have been formed by flowing fluids at some point in the past. Radar altimetry suggests height variation is low, typically no more than 150 meters. Titan was examined by both Voyager 1 and 2 in 1980 and 1981, respectively.
[55] Although most of the lakes are concentrated near the poles (where the relative lack of sunlight prevents evaporation), a number of long-standing hydrocarbon lakes in the equatorial desert regions have also been discovered, including one near the Huygens landing site in the Shangri-La region, which is about half the size of Utah's Great Salt Lake.
That energy pushes the moon further away. There are also streaky features, some of them hundreds of kilometers in length, that appear to be caused by windblown particles. [8], As NASA notes in its news article on the June 2010 findings: "To date, methane-based life forms are only hypothetical. Template:Use mdy dates It landed on Titan's surface on January 14, 2005.
Titan is unique in our solar system. While infill from various geological processes is one reason for Titan's relative deficiency of craters, atmospheric shielding also plays a role; it is estimated that Titan's atmosphere reduces the number of craters on its surface by a factor of two. Background stars in images captured by Cassini helped the researchers track Titan. [76][77] In 2004 Cassini also detected an unusually bright feature (called Tortola Facula), which was interpreted as a cryovolcanic dome. Titan is possible canditate for harbouring life. In March 2007, NASA, ESA, and COSPAR decided to name the Huygens landing site the Hubert Curien Memorial Station in memory of the former president of the ESA. The surface is composed mainly of water ice, hydrocarbons, and possibly methane and ammonia ice. Be on the lookout for your Britannica newsletter to get trusted stories delivered right to your inbox. [22], The moons of Jupiter and Saturn are thought to have formed through co-accretion, a similar process to that believed to have formed the planets in the Solar System.

[42] These impacts appear to be relatively young, opposed to the moon's age. This is almost the same time it takes Saturn to rotate or spin around its own axis - one full spin. But humans could not breathe it as it's very cold, and also poisonous. There has also been a proposal for a Titan Mare Explorer (TiME), which would be a low-cost lander that would splash down in a lake near Titan's north pole and float on the surface of the lake for 3 to 6 months. A smaller lake, Ontario Lacus, with a shrinking shoreline, has been observed in the south polar region. Lainey worked on the study as a scientist at NASA's Jet Propulsion Laboratory. The large dark region is Shangri-la. "This result brings an important new piece of the puzzle for the highly debated question of the age of the Saturn system and how its moons formed," said Valery Lainey, lead study author and scientist at Paris Observatory at Université Paris Sciences et Lettres, in a statement. “River” channels coated with dark hydrocarbon deposits are common, sometimes running along faults and sometimes with extensive tributary systems. If the eccentricity is more than 0, the path is less round (see image below). [124] Water is a stronger solvent than methane. It is the second-largest moon in the Solar System, after Jupiter's moon Ganymede, and is larger by volume than the smallest planet, Mercury, although only about 41% as massive.
[14] Viewed from Earth, the moon reaches an angular distance of about 20 Saturn radii (just over 1.2 million km) from Saturn and subtends a disk 0.8 arcseconds in diameter. Titan is never visible to the naked eye, but can be observed through small telescopes or strong binoculars. An example of "synchronous rotation": the moon takes the same time to orbit around the planet as the planet takes to spin around its own axis. Overview of the Cassini spacecraft's investigation of Saturn's moon Titan. It's the only known moon with a considerable atmosphere and the only planetary body in addition to Earth with liquid rivers and lakes on its surface. the likely supplier is underground aquifers.
