Gulu la akatswiri a zakuthambo ochokera ku projekiti yasayansi yomwe ikufunafuna zamoyo zakuthambo, zomwe malemu Stephen Hawking anali gawo lawo, atangopeza kumene komwe kungakhale umboni wabwino kwambiri mpaka pano kwa mbendera yachilendo yomwe imachokera kunja.
Makamaka, ofufuza apeza "ma radio ochititsa chidwi" ochokera ku Proxima Centauri, makina oyandikira kwambiri a dzuŵa, zaka zowala 4.2 kuchokera ku Dzuwa.
Chizindikiro
Chizindikiro chodabwitsa chawailesi yochokera kwa oyandikana nawo kwambiri, Proxima Centauri, "akufufuzidwa mosamala" ndi gulu la akatswiri a zakuthambo ochokera ku projekiti Kubowola Mverani.
Chizindikirocho, chomwe chimangowoneka ndikusintha pang'ono pamagulu ang'onoang'ono a 980 megahertz - omwe amafanana ndi dera lawailesi yomwe nthawi zambiri imasowa ma satelayiti ndi ndege zonyamula anthu kapena - idalandiridwa kale ndi wayilesi ya Australia Parkes telescope mu Epulo ndi Meyi 2019, malinga ndi lipoti lofalitsidwa ndi The Guardian.
Chizindikirocho, malinga ndi asayansi, chinachokera kulunjika kwa nyenyezi Proxima Centauri, yomwe ndi yoyandikana kwambiri ndi dzuwa lathu mlengalenga.
Chotsatira b
Centauri B akuwonetsedwa ngati miyala yowuma (koma yopanda madzi) yamiyala Super-Earth. Kuwonekeraku ndi chimodzi mwazotheka kuthekera kwa malingaliro amakono okhudzana ndi chitukuko cha exoplanet, pomwe mawonekedwe ndi mawonekedwe apadziko lapansi sadziwika m'njira iliyonse pakadali pano. Proxima Centauri b ndiye exoplanet woyandikira kwambiri ku Sun komanso ndi exoplanet yoyandikira kwambiri yomwe ingakhalemo. Imazungulira Proxima Centauri, nyenyezi yofiyira yotentha ndi kutentha kwa 3040 K (kotentha kwambiri kuposa mababu oyatsira motero yoyera, monga akuwonetsera apa).

Proxima Centauri ili ndi zaka zowala 4.2 kuchokera Padziko Lapansi (pafupifupi ma kilomita 40 trilioni) ndipo ili ndi mapulaneti awiri otsimikizika, chimphona chonga cha Jupiter komanso dziko lamiyala longa Dziko lapansi lotchedwa Proxima B ku "malo okhalamo", komwe ndi komwe madzi amadzi amatha kuyenda padziko lapansi.
Komabe, popeza Proxima Centauri ndiwofiyira, malo okhalamo ali pafupi kwambiri ndi nyenyeziyo. Izi zikutanthawuza kuti dziko lapansi lingakhale lotsekeka ndi mafunde komanso kuwonetseredwa ndi cheza choopsa, ndikupangitsa kuti mwina chitukuko chilichonse sichingakhazikike, pamwamba pake.
Dziko lachitatu mkati mwa dongosolo?
Chizindikirocho, chomwe sichinatchulidwepo ndi zinthu zilizonse zapadziko lapansi kapena zopangidwa ndi anthu pafupi ndi Dziko Lapansi, zikuyenera kukhala ndi tanthauzo lachilengedwe komabe. Ngakhale zili choncho, akatswiri osaka zakuthambo achilendo adadabwitsidwa ndi chizindikiro chodabwitsa.
Chifukwa chake, chizindikiritso chawailesi chomwe chimapezeka mu 980 megahertz range, kuphatikiza pakusintha kwakanthawi kodziwika ndi telescope ya Parkes, kumagwirizana ndi kayendedwe ka dziko. Izi zikusonyeza kuti ukhoza kukhala umboni woti dziko lachitatu lili m'dongosolo lino, m'malo mongokhala zisonyezo zakutundu wachilendo, zomwe ofufuzawo akuti "sizokayikitsa".
A Pete Worden, director of Breakthrough Initiatives, adauza The Guardian kuti zizindikirazo mwina ndizosokonekera kuchokera kuzinthu zomwe sitingathe kufotokoza. Komabe, adati ndikofunikira kudikirira kuti tiwone zomwe asayansi akumaliza pomaliza kuyang'anitsitsa chizindikirocho.
Wow!
Timuyi yati iyi ndi imodzi mwamawayilesi osangalatsa kwambiri kuyambira pamenepo Wow! zomwe zidapangitsa ambiri kulingalira kuti zidachokera ku chitukuko chakunja chakunja.
Wow! anali wailesi yayifupi, yopanda zingwe yomwe idatengedwa pakufufuza pulogalamu yakunja (Seti), ndi Big Ear Radio Observatory ku Ohio mu 1977.
Chizindikiro chosazolowereka, chomwe chinadzitcha dzina la katswiri wa zakuthambo Jerry Ehman atalemba kuti "Wow!" Kuphatikiza pa zomwe zidafotokozedwazo, zidadzetsa chisangalalo, ngakhale Ehman adachenjeza kuti asaganizire "zambiri zazitali."
