Organic Chemistry and Exobiology on Titan

  title={Organic Chemistry and Exobiology on Titan},
  author={François Raulin and Tobias C. Owen},
  journal={Space Science Reviews},
Exobiology is not only the study of the origin, distribution and evolution of life in the universe, but also of structures — including at the molecular level, and processes — including organic chemical transformations — related to life. In that respect, with its dense nitrogen atmosphere, which includes a noticeable fraction of methane, and the many organic compounds which are present in the gas and aerosols phases, Titan appears to be a planetary object of prime interest for exobiology in the… 

The new Titan: an astrobiological perspective

Since the first Voyager data, Titan, the largest satellite of Saturn and only satellite in the solar system having a dense atmosphere, became one of the key planetary bodies for astrobiological

Exo-Astrobiological Aspects of Europa and Titan: From Observations to Speculations

By extrapolating what we know on the origins of life on Earth, and in particular on the chemical processes which gave rise to the first living system, Europa and Titan appear as two major targets for

Biologically enhanced energy and carbon cycling on Titan?

With the Cassini-Huygens Mission in orbit around Saturn, the large moon Titan, with its reducing atmosphere, rich organic chemistry, and heterogeneous surface, moves into the astrobiological

Water, Life, and Planetary Geodynamical Evolution

Abstract In our search for life on other planets over the past decades, we have come to understand that the solid terrestrial planets provide much more than merely a substrate on which life may

Six Phases of Cosmic Chemistry

The article presents a conceptually unified, quantitative account of the development of chemical phenomena throughout the cosmic history, with a detailed discussion of the cosmological,

Planetary Mass Spectrometry for Agnostic Life Detection in the Solar System

For the past fifty years of space exploration, mass spectrometry has provided unique chemical and physical insights on the characteristics of other planetary bodies in the Solar System. A variety of

The prospect of alien life in exotic forms on other worlds

A detailed discussion of two possible habitats for alien life which are generally not considered as such: the lower cloud level of the Venusian atmosphere and Titan’s surface environment are provided.

A view of extraterrestrial soils

The nature of soils on celestial bodies other than Earth is a growing area of research in planetary geology. However, disagreement over the significance of these deposits arises, in part, through the

Viroids-First—A Model for Life on Earth, Mars and Exoplanets

This article thinks that “viruses-first” can be specified to “viroids- first” as the most likely scenario for the emergence of life on Earth, and possibly elsewhere.

ALMA detection and astrobiological potential of vinyl cyanide on Titan

The first spectroscopic detection of vinyl cyanide in Titan’s atmosphere is reported using archival data from the Atacama Large Millimeter/submillimeter Array (ALMA), collected from February to May 2014.

The low temperature organic chemistry of Titan's geofluid.

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.

Organic chemistry in Titan's atmosphere: new data from laboratory simulations at low temperature.

Chemistry and evolution of Titan's atmosphere

Abstract The chemistry and evolution of Titan's atmosphere is reviewed in the light of the scientific findings from the Voyager mission. It is argued that the present N2 atmosphere may be Titan's

Organic syntheses from CH4−N2 atmospheres: Implications for Titan

Numerous experiments have already been performed, simulating the evolution of gaseous mixtures containing CH4 when submitted to energy flux. From their results, it appears that a variety of organic

Photochemical modeling of Titan's atmosphere

A new photochemical model of Titan's atmosphere which includes all the important compounds and reactions in spherical geometry from the surface to 1240 km is developed and is in a closer agreement with the abundances inferred from the Voyager infrared measurements at the equator than the Yung et al. results.
