Umfanekiso - SETI
Siphila kwiplanethi apho kukho yonke into: iingingqi apho imvula inetha kakhulu ukuya kuthi ga kwinqanaba lokuba izikhukula zezona ngxaki ziphambili, ezinye apho kunetha ngokulinganayo, kwaye ezinye apho zingawi ngaphezulu kweesentimitha ezimbalwa ... hayi zonke iminyaka. Olu hlobo lweendawo kunye nemozulu zenza uMhlaba ube likhaya elimangalisayo.
Kodwa, Wakhe wazibuza ukuba iphi imvula encinci? Ukuba kunjalo, ungaphoswa leli nqaku. Masifumanise ukuba yeyiphi eyona ndawo yomileyo emhlabeni.
Indawo eyomileyo nguMaría Elena Sur (INYANGA). Ifumaneka kwingingqi yeYungay, kwintlango ye-Atacama (eChile), i-MES yeyona ndawo yomileyo kwiplanethi yoMhlaba. Ngomyinge we-atmospheric relative humidity (RH) we-17,3% kunye ne-RH emhlabeni ene-14% rhoqo kubunzulu bemitha enye, sinokucinga ukuba ubomi abunakuphila apha ... kodwa singangaba asilunganga.
Iimpawu zale khola zifana naleyo iplanethi yethu engummelwane, iMars, kodwa izazinzulu zifumene iintsholongwane ezihlala kwezi meko zimbi ngokweenkcukacha ezipapashwe kwiphephancwadi lengxelo i-Environmental Microbiology Reports.
Umfanekiso-Armado Azúa-Bustos
Ezi microorganisms zifunyenwe kwiindlela zebhayoloji zebhayoloji zinokusinceda siqonde ubudlelwane phakathi kobomi namanzi. Abasindi kuphela kwingingqi eyomileyo kwihlabathi, kodwa banokunyamezelana okukhulu kwimitha yelanga.
Ukuba kukho ubomi ENYANGA, ngaba kungakho ubomi eMars? Ewe kunokwenzeka. Isazinzulu sase-Chile u-Armado Azúa-Bustos uthe "ukuba kukho imeko efanayo eMhlabeni apho sifumene khona ii-microorganisms ezinokwenzeka, iimeko zokufumaneka kwamanzi zibonakala ngathi azithinteli ubomi kwi-Mars", into emangalisayo, akunjalo? ucinga?
Ukuqonda iziseko zeemolekyuli zokunyamezelana okuphezulu kwimbalela kungasinceda ukuba sikhulise izityalo ezinganyangekiyo, ngubani owaziyo, mhlawumbi sinokuba nemithi yeziqhamo okanye izityalo zegadi ezingadingi manzi maninzi.
