Astrobiologia, olim exobiologia appellata, est campus scientificus interdisciplinarius qui origines, evolutionem primam, distributionem, futurumque vitae in universo tractat. Astrobiologia utrum vita extraterrestris exsistat an non rogat, et si exsistit, quomodo homines eam detegere possint.[2][3]

Acida nucleica non solae biomoleculae in universo esse possunt, quae rationes vitae codificare possunt.[1]
Asteroides vitam ad tellurem fortasse portaverunt.

Astrobiologia disciplinis biologia moleculari, biophysica, biochemia, chemia, astronomia, cosmologia physica, exoplanetologia, geologiaque utitur ad vitam futuram in aliis mundis investigandam et biosphaeria quae a vita terrestri differre possunt agnoscenda.[4] Origo et prima vitae evolutio sunt inseparabilis disciplinae astrobiologiae pars.[5] Astrobiologia data scientifica exstantia interpretatur, et, quamquam eruditi coniecturas contextuales faciant, plerumque hypotheses quae theoriis scientificis omnino aptas tractat.

Historia et etymologiaRecensere

Vocabulum astrobiologia primum Russice a Gabriele Tikhov, astronomo Russico, anno 1953 propositum est.[6] Quod nomen a Graecis ἄστρον 'stella, constellatio' + βίος 'vita' + logia 'studium' derivatur.

Aliud nomen olim in usu inter astronomos est xenobiologia ('biologia peregrinorum'), vocabulum anno 1954 a Roberto Heinlein, scriptore fictionis scientificae in mythistoria The Star Beast ('bestia stellarum') adhibitum.[7]

Aequatio DrakianaRecensere

Aestimatio numeri planetarum quibus est vita extraterrestris communicativa ex aequatione Drakiana colligi potest, aequatione quae probabilitatem vitae intellegentis ut exitus factorum sicut pars planetarum quae habitari possunt et pars planetarum ubi vita oriri potest.[8]
