The Glitter of Distant Seas

  title={The Glitter of Distant Seas},
  author={R. Lorenz},
  pages={403 - 404}
It has long been known that Saturn's largest moon, Titan, has a thick nitrogen atmosphere, which obscures the underlying surface. In his Perspective, Lorenz highlights the report by Campbell et al., who have used the giant Arecibo and Green Bank radio telescopes as a radar to probe Titan's hidden surface. The surface appears to be distinct from those of the icy satellites of Jupiter, in both brightness and polarization. The new data show sharp spikes in the reflected microwave spectrum… Expand
Sea-surface wave growth under extraterrestrial atmospheres: Preliminary wind tunnel experiments with application to Mars and Titan
Abstract We describe for the first time the generation and measurement of capillary waves in a water surface in a wind tunnel running with air at pressures of 15–1000 mbar. These experiments suggestExpand
Detecting the glint of starlight on the oceans of distant planets
Abstract We propose that astronomers will be eventually be able to discriminate between extrasolar Earth-like planets with surface oceans and those without using the shape of phase light curves inExpand
Meteorological assessment of the surface temperatures on Titan: constraints on the surface type
Abstract The latitudinal profile of near-surface air temperature on Titan retrieved by Voyager 1 has been difficult to understand and raised several speculations about possible exotic processes thatExpand
Atmospheric Electrification in the Solar System
Atmospheric electrification is not a purely terrestrial phenomenon: all Solar System planetary atmospheres become slightly electrified by cosmic ray ionisation. There is evidence for lightning onExpand
The application of Laser Induced Breakdown Spectroscopy (LIBS) to the analysis of geological samples in simulated extra-terrestrial atmospheric environments
Laser induced breakdown spectroscopy (LIBS) is a technique that can determine the elemental composition and quantities of a sample by the spectral analysis of a laser induced plume. This study wasExpand
Prokaryotic diversity of arctic ice shelf microbial mats.
Findings provide the first insight into the prokaryotic biodiversity of Arctic ice shelf communities and underscore the importance of these cryo-ecosystems as a rich source of microbiota that are adapted to extreme cold. Expand


Evidence for the Exposure of Water Ice on Titan's Surface
A spectrum of Titan's surface within these “windows” was derived and features characteristic of water ice were detected, suggesting that despite the hundreds of meters of organic liquids and solids hypothesized to exist on Titan’s surface, its icy bedrock lies extensively exposed. Expand
Radar Reflectivity of Titan
The present understanding of the atmosphere and surface conditions on Saturn's largest moon, Titan, including the stability of methane, and an application of thermodynamics leads to a strongExpand
Radar Evidence for Liquid Surfaces on Titan
Arecibo radar observations of Titan indicate that most of the echo power is in a diffusely scattered component but that a small specular component is present for about 75% of the subearth locations observed. Expand
Titan: High-Resolution Speckle Images from the Keck Telescope
Abstract Saturn's large moon Titan is unique among planetary satellites in that it possesses a thick atmosphere and a haze layer that is opaque to visible light. This haze is believed to be composedExpand
Radar Investigation of Mars, Mercury, and Titan
Radar astronomy is the study of the surfaces and near surfaces of Solar System objects using active transmission of modulated radio waves and the detection of the reflected energy. The scientificExpand
Abstract A number of recent observational results concerning Titan's surface are synthesized in order to constrain possible surface physical states and compositions. With the remote sensing data as aExpand
Impacts and cratering on Titan: a pre-Cassini view
Abstract Titan is an outstanding object in terms of its usefulness for comparative planetology. While essentially an icy giant satellite like Ganymede and Callisto, its thick atmosphere makes it aExpand
Titan's Surface, Revealed by HST Imaging
We present for the first time relative albedo maps of Titan's surface. The maps were made from images taken by the Hubble Space Telescope's planetary camera (295 km per pixel) through atmosphericExpand
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
The tide in the seas of Titan
The surface temperature of Titan1 is about 95 K, between the melting point (90.6 K) and the boiling point (118 K) of methane at the total surface pressure of 1.6 bar. Voyager 1 IR observations1,2Expand
