Présentation. Exobiologie, aspects historiques et épistémologiques
The definition of exobiology – the study of the origins, evolution and distribution of life in the universe, as well as of related structures and processes – raises the problem of the link between current and past studies on the origins of terrestrial ...

“Freezing” Thermophiles: From One Temperature Extreme to Another
New detections of thermophiles in psychrobiotic (i.e., bearing cold-tolerant life forms) marine and terrestrial habitats including Arctic marine sediments, Antarctic accretion ice, permafrost, and elsewhere are continually being reported.

How Can Linguistics Help to Structure a Multidisciplinary Neo Domain such as Exobiology?
This chapter examines the contribution that corpus linguistics can make towards stabilising definitions within exobiology. By using the clues provided by natural language processing tools, linguists build an interpretation of contexts and try to show how

Doppler cross-correlation spectroscopy as a path to the detection of Earth-like planets
In the middle of the 20th century, a paradigm shift appeared concerning the expected frequency of planetary systems in the galaxy ...a shift induced by the observation of the rotational velocities of low main sequence stars (Struve 1952)!At the same time,

Genomic Features of the Bundle-Forming Heliobacterium Heliophilum fasciatum
Eight species of heliobacteria have had their genomes sequenced. However, only two of these genomes have been analyzed in detail, those from the thermophilic Heliomicrobium (Hmi.) modesticaldum and the alkaliphilic Heliorestis (Hrs.) convoluta.

Ladderpath Approach: How Tinkering and Reuse Increase Complexity and Information
The notion of information and complexity are important concepts in many scientific fields such as molecular biology, evolutionary theory and exobiology. Many measures of these quantities are either difficult to compute, rely on the statistical notion of ...
