Titan is the only satellite in our Solar System with a dense atmosphere. The surface pressure is 1.5 bar (ref. 1) and, similar to the Earth, N2 is the main component of the atmosphere. Methane is the second most important component, but it is photodissociated on a timescale of 107 years (ref. 3). This short timescale has led to the suggestion that Titan may possess a surface or subsurface reservoir of hydrocarbons to replenish the atmosphere. Here we report near-infrared images of Titan… Expand
Saturn's largest satellite, Titan, has a thick atmosphere dominated by nitrogen and methane. The dense orange-brown smog hiding the satellite's surface is produced by photochemical reactions ofExpand
Titan: an astrobiological laboratory in the solar system
After only three years of close observation from the Cassini-Huygens mission, Titan appears more and more as one of the key planetary bodies in the solar system for astrobiological studies. TitansExpand
Episodic outgassing as the origin of atmospheric methane on Titan
This work shows that episodic outgassing of methane stored as clathrate hydrates within an icy shell above an ammonia-enriched water ocean is the most likely explanation for Titan's atmospheric methane, and predicts that future fly-bys should reveal the existence of both a subsurface water ocean and a rocky core, and should detect more cryovolcanic edifices.

Saturn's Titan: Surface change, ammonia, and implications for atmospheric and tectonic activity
Titan is known to have a young surface. Here we present evidence from the Cassini Visual and Infrared Mapping Spectrometer that it is currently geologically active. We report that changes in theExpand
Titan's surface geology
2.1 Overview The presence of an atmosphere, initially suggested based on limb darkening by Sola (1904) and later by the presence of methane spectral lines by Kuiper (1944), has long given Titan aExpand
T The Exploration of Titan
INTRODUCTION The most Earth-like body in the solar system is not another planet but Saturn’s largest moon, Titan.1 Indeed, if Titan orbited the Sun rather than Saturn, we would not hesitate to callExpand
Astrobiology of Titan
Mars, Europa, and Titan—these solar system bodies have a great exobiological significance. Here, we will focus on Titan, the largest satellite of Saturn, which has a dense atmosphere composedExpand
Astrobiology and habitability of Titan
Largest satellite of Saturn and the only in the solar system having a dense atmosphere, Titan is one of the key planetary bodies for astrobiological studies, due to several aspects. (i) Its analogiesExpand
Methane drizzle on Titan
It is shown that the in situ data on the methane concentration and temperature profile in Titan's troposphere point to the presence of layered optically thin stratiform clouds, indicating that methane precipitation occurs wherever there is slow upward motion. Expand

Does Titan have an ocean? A review of current understanding of Titan's surface
The nature of Titan's surface has been a fascinating puzzle since the first definitive detection of an atmosphere in 1944. Pre-Voyager models of the surface based largely on cosmochemistry and theExpand
Internal structure and dynamics of the large icy satellites
Abstract The magnetic data returned by the Galileo mission suggest that deep oceans are present within the icy Galilean satellites. In addition, tectonic features on Europa are consistent with modelsExpand
The Surface of Titan from NICMOS Observations with the Hubble Space Telescope
Abstract From diffraction-limited images produced by the near-IR camera NICMOS aboard the Hubble Space Telescope we derived maps of Titan's surface in the methane windows near 1.1, 1.6, and 2.0 μm.Expand
Photochemistry of the atmosphere of Titan: comparison between model and observations.
The photochemistry of simple molecules containing carbon, hydrogen, nitrogen, and oxygen atoms in the atmosphere of Titan has been investigated using updated chemical schemes and the authors' own estimates of a number of key rate coefficients, which satisfactorily accounts for the concentrations of minor species observed by the Voyager IRIS and UVS instruments.

Observations with the Visual and Infrared Mapping Spectrometer (VIMS) during Cassini's flyby of Jupiter
Abstract The Cassini Visual and Infrared Mapping Spectrometer (VIMS) is an imaging spectrometer covering the wavelength range 0.3–5.2 μm in 352 spectral channels, with a nominal instantaneous fieldExpand
Titan's 2 μm surface albedo and haze optical depth in 1996–2004
[1] We observed Titan in 1996–2004 with high-resolution 2 μm speckle and adaptive optics imaging at the W. M. Keck Observatory. By observing in a 2 μm broadband filter we obtain images that haveExpand
Ethane Ocean on Titan
It is proposed that Saturn's satellite Titan is covered by an ocean one to several kilometers deep consisting mainly of ethane, and the coexisting atmosphere is compatible with Voyager data. Expand
Europa: Tidal heating of upwelling thermal plumes and the origin of lenticulae and chaos melting

Abstract The icy crust of Ganymede comprises bright and dark areas. Investigation of Voyager 1 and 2 images has shown that bright terrain is grooved and separates dark polygons of cratered terrain.Expand
