Bilim insanlar\u0131, onlar\u0131 Yellowstone Milli Park\u0131’n\u0131n kaynar s\u0131cak kaynaklar\u0131ndan maden drenajlar\u0131n\u0131n asidik, metal a\u00e7\u0131s\u0131ndan zengin sular\u0131na kadar a\u015f\u0131r\u0131 ortamlarda geli\u015firken ke\u015ffettiler.<\/p>\n\n
\u015eimdi, bilim insanlar\u0131 mikroplar\u0131n ya\u015fad\u0131\u011f\u0131 bir ba\u015fka d\u00fc\u015fmanca ya\u015fam alan\u0131n\u0131 ortaya \u00e7\u0131kard\u0131lar: G\u00fcney Pasifik Okyanusu’nun alt\u0131nda, D\u00fcnya’n\u0131n kabu\u011fundaki minik, kadim \u00e7atlaklar. 100 milyondan fazla ya\u015f\u0131nda olan bu \u00e7atlaklar, s\u0131cakl\u0131ktan, besinlerden ve di\u011fer temel kaynaklardan mahrumdur.<\/p>\n\n
Bu zorlu ko\u015fullara ra\u011fmen, bu gizemli mikroplar ya\u015famay\u0131 ba\u015farm\u0131\u015flard\u0131r. Ara\u015ft\u0131rmac\u0131lar hala nas\u0131l hayatta kald\u0131klar\u0131n\u0131n gizemini \u00e7\u00f6zmeye \u00e7al\u0131\u015f\u0131yorlar, ancak bulgular\u0131, Mars’ta d\u00fcnya d\u0131\u015f\u0131 ya\u015fam aray\u0131\u015f\u0131 i\u00e7in derin sonu\u00e7lar do\u011furabilir.<\/p>\n\n
Deniz suyundaki kimyasal reaksiyonlara g\u00fcvenen di\u011fer kabukta ya\u015fayan mikroplar\u0131n aksine, bu bakteriler, ya\u015fad\u0131klar\u0131 \u00e7atlaklarda biriken mineral a\u00e7\u0131s\u0131ndan zengin kilden yararlan\u0131yor gibi g\u00f6r\u00fcn\u00fcyor. Ara\u015ft\u0131rmac\u0131 Yohey Suzuki’nin tan\u0131mlad\u0131\u011f\u0131 gibi, bu “sihirli malzeme”, besinleri k\u00fc\u00e7\u00fck alanlarda yo\u011funla\u015ft\u0131rarak, en beklenmedik yerlerde bile ya\u015fam\u0131 destekliyor.<\/p>\n\n
Ara\u015ft\u0131rmac\u0131lar ayr\u0131ca kayalarda metan yiyen mikroplar ke\u015ffettiler, ancak besin kaynaklar\u0131 belirsizli\u011fini koruyor.<\/p>\n\n
Bu dayan\u0131kl\u0131 organizmalar\u0131n D\u00fcnya’n\u0131n derin deniz kayalar\u0131nda bulunmas\u0131, g\u00fcne\u015f sisteminin ba\u015fka yerlerinde ya\u015fam belirtileri arayan bilim insanlar\u0131 i\u00e7in cesaret vericidir. Hem volkanik kaya\u00e7lar hem de metan, Mars’ta bol miktarda bulunur ve Marsl\u0131 mikroplar i\u00e7in potansiyel besin sa\u011flar.<\/p>\n\n
\u0130lgin\u00e7 bir \u015fekilde, D\u00fcnya ve Mars’taki kayalar\u0131n kimyasal bile\u015fimi olduk\u00e7a benzerdir. Dahas\u0131, Mars’\u0131n y\u00fczeyinin alt\u0131nda \u00e7oktan yok olmu\u015f bir okyanusun izleri olabilir ve bu da \u00e7atlam\u0131\u015f kabu\u011funda besinleri depolam\u0131\u015f olabilir, t\u0131pk\u0131 D\u00fcnya’n\u0131n deniz suyunun yapt\u0131\u011f\u0131 gibi.<\/p>\n\n
Ekolog Mark Lever’\u0131n \u00f6ne s\u00fcrd\u00fc\u011f\u00fc gibi, “E\u011fer ge\u00e7mi\u015fte Mars’ta ya\u015fam varsa, bug\u00fcn de bu derin yer alt\u0131 ortamlar\u0131nda ya\u015fam olmas\u0131 muhtemeldir.” Mikroplar\u0131n D\u00fcnya’n\u0131n derin deniz kayalar\u0131nda ke\u015ffi bu hipotezi g\u00fc\u00e7lendiriyor ve evrende yaln\u0131z olmad\u0131\u011f\u0131m\u0131z konusunda iyimserli\u011fi k\u00f6r\u00fckl\u00fcyor.<\/p>","protected":false},"excerpt":{"rendered":"
