Izolo NASA umemezele ukuthi namhlanje bazokhuluma ngokutholwa kwabo kwakamuva. Kwakungukungabaza okuningi njengoba i-United States Space Agency inganikwa kakhulu lolu hlobo lwezimemezelo uma izindaba zingabalulekile ngempela, kanye neqiniso lokuthi iqembu labaphenyi balo lithole uhlelo olungavamile olwakhiwe ngaphansi komhlaba eziyisikhombisa. Ama-exoplanets afana.
Lokhu kutholwa okusha kwenzeke ngenxa yamathuba ahlinzekwa ukusetshenziswa kwesibonakude iSplitzer, insimbi yeParanal VLT kanye neTrAPPIST yeLa Silla Observatory. Njengoba kuphawuliwe endabeni ekhishwe yiNature, kusobala ukuthi sikhuluma ngamaplanethi ayisikhombisa azungeza inkanyezi UTHANDO-1, etholakala eminyakeni ekhanyayo engama-38 ukusuka eLangeni okushisa kwalo kungaba phakathi kuka-0 no-100 degrees centigrade.
I-TRAPPIST-1 ingabamba ama-exoplanet ayisithupha angahle akwazi ukuhlalwa.
Wonke la maplanethi, kubonakala sengathi, angaba nosayizi ofana nalowo woMhlaba futhi, ngokusho kwezilinganiso ezenziwe ngobuningi bawo, kubonakala sengathi ososayensi babezofika esiphethweni sokuthi okungenani amaplanethi ayisithupha kwayisikhombisa atholakele a ukwakheka kwamatshe yize, njengoba ngokwabo bememezela, kusadingeka ukuthi baqhubeke nokuphenya isikhathi eside ukuze bakwazi ukukuqinisekisa ngokuqiniseka okukhulu kakhulu.
Ngenxa yalokhu okutholakele okusha, amaplanethi amasha akwazi ukugcina uhlobo oluthile lwempilo asanda kwethulwa njengoba kungafanele nje sikhulume ngama-exoplanets anesakhiwo esinamadwala, kepha futhi nangenxa yezinga lokushisa abebengatholakala kulo. kungenzeka kube namanzi uketshezi ebusweni bayo, isimo esisemqoka kuze kube manje ukuze izinto eziphilayo zikhule.
Ngokuya ngezitatimende ezenziwe ngu- Amaury triaud, umbhali osebenza ndawonye womsebenzi:
Ukukhishwa kwamandla kwezinkanyezi ezincane ezifana ne-TRAPPIST-1 kubuthakathaka kakhulu kuneLanga lethu. Ukuze kube khona amanzi ezindaweni zazo, amaplanethi kuzofanele abe semizileni esondele kakhulu kunalokhu esikubona ohlelweni lwelanga. Ngenhlanhla, kubonakala sengathi lolu hlobo lokusetha okuhlanganayo yilokho esikubonayo eduze kwe-TRASPPIST-1.
