\n\u00cen iunie 2019, o nav\u0103 spa\u0163ial\u0103 japonez\u0103 numit\u0103 Hayabusa2 a aterizat pe Ryugu, un asteroid de 900 de metri, aflat la aproximativ 295 de milioane de kilometri de P\u0103m\u00e2nt, potrivit Futurism. Nava a colectat mostre care ulterior au fost transportate pe P\u0103m\u00e2nt.<\/p>\n
\nDe atunci, oamenii de \u015ftiin\u0163\u0103 au studiat cu aten\u0163ie mostrele extrem de rare \u00eencerc\u00e2nd s\u0103 afle cum au evoluat elementele constitutive ale planetelor.<\/p>\n
\nCele mai recente descoperiri, publicate \u00een revista Nature Astronomy de o echip\u0103 de cercet\u0103tori din Japonia, arat\u0103 c\u0103 Ryugu pare s\u0103 con\u0163in\u0103 toate ingredientele necesare pentru a produce ADN-ul \u015fi ARN-ul care stau la baza vie\u0163ii pe P\u0103m\u00e2nt.<\/p>\n
\nConcluzia sus\u0163ine teoria conform c\u0103reia rocile spa\u0163iale r\u0103t\u0103citoare precum Ryugu ar fi putut aduce via\u0163a pe P\u0103m\u00e2nt cu miliarde de ani \u00een urm\u0103.<\/p>\n
\n\u201eDetectarea lor \u00een Ryugu sus\u0163ine puternic omniprezen\u0163a lor \u00een sistemul solar\u201d, a declarat Yasuhiro Oba, coautor \u015fi cercet\u0103tor la Universitatea Hokkaido, pentru New Scientist.<\/p>\n
\nOba \u015fi colegii s\u0103i au examinat mostre de suprafa\u0163\u0103 \u015fi de subsol aduse de Hayabusa2. Totu\u015fi asta \u201enu \u00eenseamn\u0103 c\u0103 via\u0163a a existat pe Ryugu\u201d, au subliniat cercet\u0103torii.<\/p>\n
\nAnul trecut, oamenii de \u015ftiin\u0163\u0103 de la NASA au dezv\u0103luit c\u0103 mostrele de praf colectate \u00een 2020 de pe un asteroid numit Bennu con\u0163ineau \u015fi ele elementele constitutive ale vie\u0163ii.<\/p>\n","protected":false},"excerpt":{"rendered":"
