Senzorii s\u0103i au detectat ceva care i-a entuziasmat foarte mult pe operatorii de pe P\u0103m\u00e2nt: un gaz numit metan. Pe P\u0103m\u00e2nt avem o cantitate mare de metan. Acesta poate fi produs at\u00e2t prin procese geologice, c\u00e2t \u0219i de c\u0103tre fiin\u021be vii.\u00a0<\/p>\n<\/div>\n<p>\u00cen \u0219tiin\u021b\u0103, cu c\u00e2t colectezi mai multe date despre un fenomen, cu at\u00e2t studiile tale pot fi mai bune.

Ei au descoperit acum c\u0103 \u0219i Mars Express a detectat metanul!\u00a0<\/p>\n<p>Deci, ce ar fi putut genera metanul de pe Marte? Metanul se descompune foarte repede odat\u0103 ce este expus chiar \u0219i la atmosfera rarefiat\u0103 a lui Marte, ceea ce \u00eenseamn\u0103 c\u0103 gazul detectat de Curiosity \u0219i Mars Express trebuie s\u0103 fi fost produs sau eliberat foarte recent. O ipotez\u0103 este c\u0103 metanul a fost produs cu milioane sau chiar miliarde de ani \u00een urm\u0103.
