Chikwata chevazivi venyeredzi kubva kuchirongwa chesainzi chiri kutsvaga hupenyu hwekunze, iko kunonoka Stephen Hawking aive chikamu, achangobva kuwana hungave hwakanakisa humbowo kusvika parizvino chiratidzo chemutorwa chinouya kubva kunze kwemuchadenga.
Kunyanya, vaongorori vakawana "inonakidza redhiyo chiratidzo" ichibva kuProxima Centauri, iri padyo zuva rezuva, ingori 4.2 makore-makore ekubva kuSuva.
Chiratidzo
Chiratidzo chisinganzwisisike cheredhiyo kubva kune wepedyo stellar muvakidzani, Proxima Centauri, iri "kunyatso kuferefetwa" nechikwata chevazivi venyeredzi kubva purojekiti Kubudirira Teerera.
Iyo chiratidzo, iyo yakaonekwa nekungochinja kudiki mune bhanhire rakamanikana remafizikisi angangoita mazana mapfumbamwe nemakumi masere megahertz - inowirirana nedunhu renhepfenyuro inowanzo kushayikwa kubva kuma satellite teresikopu muna Kubvumbi naMay 980, sekureva kweshumo rakaburitswa neThe Guardian.
Chiratidzo, sekureva kwemasayendisiti, chakabva kunzira nyeredzi Proxima Centauri, inova muvakidzani wezuva redu padenga.
Inotevera b
Centauri B inoratidzirwa senge pakaoma (asi kwete zvachose isina mvura-isina) dombo Super-Earth. Uku kutaridzika ndeimwe yemazhinji mhedzisiro anogona kuitika edzidziso dzazvino maererano nekuvandudzwa kweiyo exoplanet, nepo kutaridzika chaiko uye chimiro chenyika chisingazivikanwe nenzira dzipi panguva ino. Proxima Centauri b ndiyo exoplanet yepedyo kune Zuva uye zvakare yepedyo inogona kugara exoplanet futi. Iyo inotenderera Proxima Centauri, mutsvuku mutsvuku ane tembiricha yepamusoro ye3040 K (nekudaro inopisa kupfuura mabhuru emagetsi uye nekudaro yakachena, sezvakaratidzwa pano). Iyo Alpha Centauri binary system inoratidzwa kumashure © ESO
Proxima Centauri iri 4.2 makore-ekuyera kubva pasi (anenge makumi mana emamirioni makiromita) uye ane mapuraneti maviri akasimbiswa, Jupiter-yakafanana negasi hofori nenyika ine matombo yakaita sePasi inonzi Proxima B mu "nzvimbo inogarwa", inova nzvimbo mvura yemvura yaigona kuyerera pamusoro penyika.
Nekudaro, sezvo Proxima Centauri iri tsvuku tsvuku, inzvimbo yekugara iri padyo kwazvo nenyeredzi. Izvi zvinoreva kuti pasi rino rinogona kunge rakakiyiwa nemvura uye richionekwa nemwaranzi, zvichiita kuti zvisashande kuti chero budiriro ingave yakaumbwa, pamusoro pevhu.
Nyika yechitatu mukati meiyo system?
Iyo chiratidzo, iyo isina kuverengerwa kune chero epasirese kana masosi akagadzirwa nevanhu padhuze nepasi, anogona kunge aine tsananguro yepanyama zvakadaro. Kunyangwe zvakadaro, vatorwa muvhimi nyeredzi nyeredzi vakakatyamadzwa nechishamiso chiratidzo.
Nekudaro, iyo redhiyo chiratidzo inowanikwa mukati me980 megahertz renji, kuwedzera kune shanduko mune kuwanda kunoonekwa neParkes teresikopu, inoenderana nekufamba kwepasi. Izvi zvinoratidza kuti hungave humbowo hwepasi rechitatu mukati mehurongwa, kwete zviratidzo zvebudiriro yevatorwa, chimwe chinhu icho vanotsvaga vanoti chingave "chisingafungidzike."
Pete WordPress Nekudaro, akati zvakakosha kumirira kuti uone izvo projekiti masayendisiti anopedzisa nekunyatsoongorora chiratidzo.
Wow!
Chikwata chinoti ichi ndicho chimwe chezviratidzo zvinonakidza zveredhiyo kubva ipapo Wow! izvo zvakaita kuti vazhinji vafungidzire kuti zvakabva kune imwe nyika iri kure yakabudirira.
Wow! yaive yenguva pfupi, yakatetepa-bhendi redhiyo yakatorwa panguva yekutsvaga chirongwa chekunze kwenyika (Seti) chirongwa, neBig Ear Ear Radio Observatory muOhio muna 1977.
Iyo isina kujairika chiratidzo, iyo yakawana zita rayo mushure meyemuchadenga Jerry Ehman akanyora "Wow!" Pamwe chete nedata racho, zvakakonzera mafaro, kunyangwe Ehman akayambira nezvekutora "mhedziso hombe kubva kuhurefu hwepakati."
