ʻO nā kānaka paʻakikī ma ka lihi o ke ākea

Wahi a nā noiʻi i hana ʻia e nā microbiologists ma ke Kulanui ʻAmelika o Maryland, ma waena o nā mea ʻē aʻe, ʻo ka stratosphere ka home o nā extremophiles hiki ke pale aku i ke anuanu a me ka pōʻino ultraviolet a ʻo ia ka palena loa o ke ola honua. Makemake nā kānaka ʻepekema e hoʻomohala i kahi "Atlas of Stratospheric Microbes" e hoʻopaʻa inoa i nā microbes e noho ana ma nā wahi kiʻekiʻe.

Ua hoʻokō ʻia nā haʻawina o nā microorganism ma nā papa luna o ka lewa mai ka makahiki 30. Ua kaulana kekahi o ko lakou mau paionia Charles Lindberghnāna, me kāna wahine, i kālailai i nā laʻana lewa. Loaʻa kā lākou hui i loko o lākou, ma waena o nā mea ʻē aʻe, spores o nā haʻiki a me nā hua pollen.

I nā makahiki 70, ua hoʻokō ʻia nā haʻawina biological paionia o ka stratosphere, ʻoi aku hoʻi ma ʻEulopa a me ka Soviet Union. Ke aʻo ʻia nei ka biology atmospheric i kēia manawa, me ka papahana NASA i kapa ʻia Maluna (). E like me ka ʻike ʻana o ka poʻe ʻepekema, ua like nā kūlana koʻikoʻi o ka stratosphere o ka Honua me ko ka lewa Martian, no laila hiki i ke aʻo ʻana i ke ola stratospheric ke kōkua i ka ʻike ʻana i nā ʻano "alien" ma waho o ko kākou honua.

- - ua ʻōlelo ʻo ia ma kahi hālāwai ninaninau me "Astrobiology Magazine" Shiladitya DasSarma, he microbiologist ma ke Kulanui o Maryland. -.

ʻO ka mea pōʻino, ʻaʻole nui nā papahana noiʻi i hoʻolaʻa ʻia i nā mea ola i ka lewa. Aia nā pilikia me kēia, no ka mea, haʻahaʻa loa ka neʻe ʻana o nā microorganism ma kēlā me kēia leo. I loko o kahi ʻano ʻino, maloʻo, anuanu, i nā kūlana o ka ea laha loa a me ka radiation ultraviolet, pono nā microbes e hoʻomohala i nā hoʻolālā ola ʻano ʻano o nā extremophiles. Make maʻamau ka maʻi bacteria a me nā haʻakai ma laila, akā ola kekahi ma ka hana ʻana i nā spores e pale ai i ka mea genetic.

Ke makaʻala nei nā keʻena lewa, me ka NASA, ʻaʻole e hōʻike i nā honua ʻē aʻe i ka microfauna terrestrial, no laila e mālama ʻia nā mea ma mua o ka hoʻokuʻu ʻana i kekahi mea i ka orbit. I ka nui o nā hihia, ʻaʻole hiki ke ola nā microbes i ka pōʻino o ka hihi cosmic. Akā, hōʻike nā mea ola stratospheric hiki i kekahi ke hana. ʻOiaʻiʻo, pono e hoʻomanaʻo ʻaʻole like ke ola me ka ulu ʻana o ke ola. Ma muli wale o ke ola ʻana o kahi mea ola i ka lewa a, no ka laʻana, hiki i Mars, ʻaʻole ia he manaʻo hiki ke ulu a hoʻonui i laila.

ʻOiaʻiʻo anei - hiki ke pane ʻia kēia nīnau e nā noiʻi kikoʻī hou aku o nā mea ola stratospheric.
