Varume vakaoma vari kumucheto kwenzvimbo

Maererano nenzvero yakaitwa nenyanzvi dzezvinhu zvipenyu zvidukuduku paAmerican University of Maryland, pakati pezvimwe, stratosphere imusha wezvipembenene zvinopfurikidza mwero zvinogona kutsungirira kutonhora kwakanyanyisa uye ultraviolet bombardment uye ndiwo muganhu uri kure zvikuru wezvipenyu zvepanyika. Masayendisiti anoda kugadzira "Atlas yeStratospheric Microbes" iyo inoronga hutachiona hunogara pakakwirira.

Zvidzidzo zvema microorganisms ari kumusoro kwemuchadenga zvave zvichiitwa kubva kuma30s. Mumwe wemapiyona avo aiva nemukurumbira Charles Lindberghuyo, pamwe chete nomudzimai wake, vakaongorora masamples emuchadenga. Chikwata chavo chakawana mavari, pakati pevamwe, spores of fungi uye pollen mbeu.

Mumakore ekuma70, zvidzidzo zvehupenyu zve stratosphere zvakaitwa, kunyanya muEurope neSoviet Union. Atmospheric biology parizvino iri kudzidzwa, kusanganisira kuburikidza neprojekti yeNASA inonzi ABOVE (). Sezvakataurwa nemasayendisiti, mamiriro akanyanya muEarth stratosphere akafanana neari mumhepo yeMartian, saka kudzidza kwehupenyu hwe stratospheric kunogona kubatsira kuziva "vatorwa" vakasiyana-siyana kunze kwepasi redu.

Nehurombo, hapana zvirongwa zvakawanda zvekutsvagisa zvakapihwa kune zvipenyu zviri mumhepo. Pane matambudziko neizvi, nekuti kuwanda kwema microorganisms per unit volume yakaderera kwazvo ipapo. Munzvimbo yakaoma, yakaoma, inotonhora, mumamiriro emhepo isingawanikwe zvakanyanya uye nemwaranzi yeultraviolet, hutachiona hunofanirwa kugadzira nzira dzekupona dzemaextremophiles. Utachiona nefungi zvinowanzofira ipapo, asi vamwe vanopona nekugadzira spores inodzivirira genetic material.

Masangano emuchadenga, kusanganisira NASA, parizvino akangwarira kusafumura dzimwe nyika kune terrestrial microfauna, saka chenjedzo inotorwa isati yatanga chero chinhu munzira. Muzviitiko zvakawanda, ma microbes haagone kurarama necosmic ray bombardment. Asi zvipenyu zvine stratospheric zvinoratidza kuti vamwe vanogona kuzviita. Chokwadi, zvakakosha kuyeuka kuti kupona hakuna kufanana nekubudirira kwehupenyu. Kungoti chipenyu chinorarama mumhepo uye, semuenzaniso, inosvika kuMars, hazvireve kuti inogona kukura nekuwanda ipapo.

Izvi ndizvo chaizvo - mubvunzo uyu unogona kupindurwa neongororo dzakadzama dze stratospheric organisms.
