Exist\u0103 via\u021b\u0103 pe Marte? Cu siguran\u021b\u0103, nimeni nu se a\u0219teapt\u0103 s\u0103 g\u0103seasc\u0103 mar\u021bieni inteligen\u021bi, precum cei din filmul \u2018R\u0103zboiul lumilor\u2019. Cu toate acestea, rezultatele ob\u021binute de sonda orbital\u0103 Mars Express a ESA \u0219i de observatoarele terestre sugereaz\u0103 c\u0103 pe planeta ro\u0219ie s-ar putea ascunde forme de via\u021b\u0103 simple sub p\u0103m\u00e2nt.<\/p>\n<\/div>\n

Cheia acestui mister este metanul, un gaz folosit pe P\u0103m\u00e2nt pentru g\u0103tit \u0219i \u00eenc\u0103lzire. O mare parte din metanul din atmosfera noastr\u0103 este eliberat de forme de via\u021b\u0103 evoluate, cum ar fi vitele care diger\u0103 hrana. Cu toate acestea, exist\u0103 \u0219i alte modalit\u0103\u021bi de a produce metan, cum ar fi activitatea vulcanic\u0103.<\/p>\n

Metanul a fost descoperit pe Marte \u00een 2003. Deoarece acest gaz se descompune u\u0219or, se estima c\u0103 durata sa de via\u021b\u0103 \u00een atmosfera mar\u021bian\u0103 ar fi de aproximativ 300 de ani. O analiz\u0103 mai detaliat\u0103 a ar\u0103tat c\u0103 metanul era, de fapt, concentrat \u00een trei regiuni. Acest lucru a demonstrat c\u0103 era eliberat chiar \u00een acel moment, iar noi \u00eel detectam \u00eenainte ca acesta s\u0103 apuce s\u0103 se r\u0103sp\u00e2ndeasc\u0103 pe toat\u0103 suprafa\u021ba planetei.<\/p>\n

Apoi, Marte a rezervat o alt\u0103 surpriz\u0103. \u00cen loc s\u0103 dureze 300 de ani p\u00e2n\u0103 s\u0103 dispar\u0103, metanul se evaporase aproape \u00een totalitate p\u00e2n\u0103 la \u00eenceputul anului 2006. Ceva \u00eel elimina din atmosfer\u0103 de 600 de ori mai repede dec\u00e2t se a\u0219tepta. Oamenii de \u0219tiin\u021b\u0103 de la ESA b\u0103nuiesc c\u0103 suprafa\u021ba planetei ar putea fi de vin\u0103. Fie metanul este re\u021binut \u00een praf, fie substan\u021be chimice extrem de reactive, precum peroxidul de hidrogen, \u00eel distrug. Acest lucru ar putea \u00eensemna c\u0103 suprafa\u021ba este mult mai ostil\u0103 vie\u021bii dec\u00e2t se credea anterior. Dac\u0103 este a\u0219a, viitorii exploratori vor trebui s\u0103 foreze ad\u00e2nc \u00een subteran pentru a c\u0103uta semne de via\u021b\u0103 trecut\u0103 sau prezent\u0103.<\/p>","protected":false},"excerpt":{"rendered":"
