Isignali kusuka engase sikulungele ukuba kuphilwe kuso iplanethi Gliese 581d

Ososayensi baye baphawula isiginali kusuka iplanethi Gliese 581d, futhi wakwazi ngazisa ukuthi izimo therein Site emizameni kanye nokugcinwa impilo. Okwamanje, kuyaziwa ukuthi nendikimba ethile esemkhathini usayizi izikhathi Earth 2. Isignali ye-zalotshwa isikhathi eside, kodwa kuphela 2014 wakwazi ukubona ukuthi basuke okuphindiwe, kukhona cyclical. Ayikho esenzeka yonke ayikwazi ukwenza lokhu, ngaphandle-ke, it is hhayi wadala eyayenziwe.

Isignali ye-ibonisa ukuthi impucuko ezisemkhathini emhlabeni, ukuzama ukuletha umlayezo izinhlelo angomakhelwane imithala. Kodwa wokufunda "incwadi" kuze kube manje kuhlulekile.

mayelana iplanethi

Exoplanet Gliese 581d ungaphakathi uhlelo elinegama elifanayo (Gliese 581). Okwamanje, khona akachaziwe ngokunembile, kodwa zonke izinkomba zibonisa ukuthi ukhona ngempela. Iplanethi itholakala umlaza Libra, okuyinto impela ekubeni yesimiso sethu sonozungezilanga. Ngaphambi kwakhe - ukukhanya-iminyaka engu-20 kuphela.

Uma ukholwa ukuthi ulwazi olutholwe ku-September 2010, kubhekwa iplanethi ohlelweni salo endaweni yesihlanu inkanyezi (Earth - owesithathu, ngemva Venus futhi Mercury). Izazi eziningi bakubize ngokuthi "super-Earths", njengoba nje iye ube usayizi omkhudlwana kunalokho wonke ezikhathini 2. Futhi isisindo salo ngaphezulu izikhathi 6-8.

Umyalezo wokuqala wathola exoplanet engase sikulungele ukuba kuphilwe kuso etholwe Switzerland-April 24, 2007. Bekanye eqoshiwe Gliese 581d futhi Gliese 581c. Ukuvulwa kungokwalabo ababhula ngezinkanyezi eziningana, abenza izenzo iqondiswa ngu Stefan Udri.

Ososayensi namanje bebaphikisana ngani ngokoqobo iplanethi, kodwa ezindabeni ukuhlola umkhathi lihlangane njalo abagxeki.

inqubo ukuthola

Uma sikholwa idatha ochwepheshe British kanye ithimba labo zezinkanyezi wabanjwa isigijimi esivela iplanethi Gliese 581d. Lapho ulwazi kuqinisekisiwe, ukuphikisana mpikiswano phezu khona kwezindikimba zasezulwini luzomiswa unaphakade. Manje kukhona okuningi imicabango yabantu ngalolu daba, ngoba ngokoqobo emhlabeni ziphethe anomalies ngokomzimba, okuyinto bamba eliwumhlaba ubuchwepheshe.

Ekuqaleni kwakunebandla elilodwa nje kuphela indlela ukuthola izindikimba zasezulwini. ukuphequlula yabo ngezibonakude ezinamandla kakhulu lapho bephumelela phambi inkanyezi zawo. Kuyinto ubuchwepheshe ezisetshenziswa ososayensi American ngo-2014.

Kodwa nabo baseBrithani baye bakungabaza ukuhlobana ndlela. Kungasiza uthola nje imidondoshiya igesi like Jupiter yethu. Bona wasebenzisa ngaphezulu ubuchwepheshe besimanje, eyaqinisekisa indawo kanye ngokoqobo emhlabeni.

Manje sibizwa ngokuthi Gliese 581d mhlawumbe simele iplanethi engase okuhlalekayo ise eponymous abomvu uhlelo yemifino. ibanga Ezazimzungezile - 20 iminyaka ukukhanya.

isignali Izimpawu

Lapho ososayensi sokuqala esilotshwe isiginali kusuka iplanethi Gliese 581d, ayizange unamathisele ukubaluleka kakhulu kuso. Khona-ke ukuba khona uqobo ngumbuzo omkhulu, kulesi senzakalo babe nezingxoxo eziningi. Ezinye izazi zezinkanyezi basakholelwa amasignali wawubonakalisa okulula umsebenzi lezinkanyezi, kodwa yanyuka, ngoba uma kungenjalo babengeke bakwazi ukufinyelela Solar System.

Ngo-2014, ososayensi American ngokuphindiwe bahlola izici isignali okuholela. Bathola ubufakazi bokuthi lo fed eyayenziwe. Izazi zezinkanyezi bakholelwa ukuthi is phetho emisebeni ukukhanya kazibuthe lokusakaza yemifino abomvu. Ezimpambanweni zomgwaqo bazobambisana ukwakha umsindo ekhethekile cosmic engakwazanga ukubamba ngaphambili.

Mashi 7 kulo nyaka, yabe seyaziwa ukuthi isiginali nge engase sikulungele ukuba kuphilwe kuso iplanethi Gliese 581d akuwona umphumela umsindo cosmic. Waphinde wamnika njalo ezinyangeni ezimbalwa, umjikelezo ofanayo.

mpikiswano obusolisayo

Ngemva kombiko itholiwe ku kuvulwa emhlabeni, idatha sayihlolisisa usebenzisa ngamahabhu. Kodwa kokutholakala ososayensi Swiss alikaqinisekiswa. izazi zezinkanyezi isiRashiya baye Uzame ukuthola nendikimba ethile esemkhathini ngenxa yobuchwepheshe yayo kuze 2012. Khona-ke usosayensi Roman Baluev waveza ukungabaza mayelana okuso.

Ngo-2014, imizamo ukuqinisekisa ukuba khona Gliese 581d ngofaka izazi zezinkanyezi e-University of Pennsylvania. Izibalo Kwakuseshwa, okuyinto inqatshelwe ulwazi Stefan Udry. Ngokusho kwabo, lomkhuba fixed - it is kuphela phetho Umsebenzi lezinkanyezi.

Ekuqaleni kwentwasahlobo ka-2015 liye waphenywa ukuphikisa ka Gliese idatha 581d. ososayensi baseBrithani wafunda izindlela ukuthola amaplanethi US izazi zezinkanyezi. Bakhuluma yokuthi lezi zindlela sikude kakhulu nokuphelela kanye nezidingo yesimanje.

Ngakho, uma iplanethi wangabaza Gliese 581d ngqo uqobo, isiginali kusuka kuye, futhi, ayikho. Okungenani namuhla akukho ubufakazi obucacile okuso.

Ngokuqondene isignali, abagxeki ukhombe ukukhanya nemisebe kazibuthe. Uma they okwakuthandelene, kungaba ezishisa kakhulu zikhipha izinhlayiyana isici umsindo ukuthi abantu zabheka ngoba umlayezo ezisemkhathini. cyclical lakhe empeleni ayikho. Esiginali uyashintsha, kodwa kancane kakhulu, efana konke okwenzekayo yonke (maqondana nezimpilo zabantu).

Imicabango kanye Sokuzenzela

Naphezu ukungezwani izazi zezinkanyezi, evela emazweni amaningi, ososayensi baseBrithani akholelwa ukuthi ukhona Gliese 581d iplanethi. Ngaphezu kwalokho, bababukela bagcizelele ukuthi amasignali okokufaka ukumela algorithm ngekhodi izimpawu ezithile. Labo ndawonye eziya izinhlelo angomakhelwane imithala.

Izazi zezinkanyezi kwaseBrithani bakholelwa ukuthi ukube zihilela imishini zobuchwepheshe hhayi kuphela, kodwa izindlela nocwaningo lwanamuhla, uzokwazi ukuhlukanisa isiginali kusuka umsindo uqobo. Ungabese uzame ukususa ukubhala ngekhodi ngaso. Mhlawumbe impucuko kohlelo Gliese futhi uzama ukuthola abafowabo engqondweni.

Ngenxa eminingi ikhompyutha sekusetshenziswa sakwazi ukumisa ukuthi kukhona amanzi olwandle planethi enixoxa ngalo. Kuyaqapheleka futhi khona amafu emkhathini futhi kwezulu ezonini abafanele. Futhi njengoba phambilini libike ukuthi ukuphila wazalwa, idinga amanzi. Ngenxa yalokho, Gliese efanelekayo ngazo zonke izindlela ngoba kule ndawo. Itholakala endaweni evumayo maqondana inkanyezi yayo, it has amanzi, futhi isemafwini kwezulu ibonisa ukusakazwa kwalo.

idatha umumo gagasi

Akekho ongasho ngokuqondile ngesikhathi kuqala bafaka isignali planethi Gliese 581d. Ekuqaleni, wayengabhekiseli athathwe ngokungathi sína, ngoba ke nendikimba ethile esemkhathini kakhulu engakaze ezitholakele. Kamuva, ngemva ingxoxo lokuqala ngayo, thina ngonanzelelo ngokoqobo iplanethi, hhayi umyalezo.

Kwaze kwaba sentwasahlobo ka-2015 kwathiwa bazitshela ukuthi isiginali umane ungumsindo ezivamile cosmic. Lezi amaza omsindo kakade wabanjwa ngamazwi imishini yasemhlabeni, futhi ngokuphindaphindiwe.

Manje Izazi zezinkanyezi zithi kungenxa ukuthi isiginali iyaphindwa ngezikhawu iDemo. It ivele igcwale umsindo, kodwa imizamo ziyaqhubeka ukususa umyalezo. Ekugcineni, laba bacwaningi ukuhlela ukuqopha amasignali planethi engase sikulungele ukuba kuphilwe kuso.

Ukuxhumana impucuko ezisemkhathini

Uma kwenzeka ukuthi Gliese 581d kuyoba ngempela ngempela abantu futhi emhlabeni lalinamaJuda, ukuthi isintu sidinga ukuba uqaphele ekuzameni iba nengxoxo nalo. Usosayensi Stiven Hoking ubizelé ngokuphindaphindiwe abantu ukuba baxwaye yokuxhumana ne impucuko ezisemkhathini.

Uthi akhe athi kakhulu ngokwezimali kunoma yiliphi nendikimba ethile esemkhathini ukuthi unokuthile efana wonke, kulinganiselwe. Zingase ayeke. Bese kuthi-ke izakhamizi kuyodingeka akukho abangakwenza ngaphandle kokuhlala ukufuna iplanethi efanayo ukuyisebenzisa deku imithombo.

isiphetho

Naphezu kobuningi yempikiswano nezingxoxo zokungabaza emhlabeni Gliese 581d, ososayensi abaningi, kanye nabo bonke abantu Earth, ngabe kakhulu afana ukuthi lalakhiwe. Ngemva kwalokho, isintu siyoba nethuba ukuze baxoxelane okuhlangenwe nakho ulwazi, ngempumelelo ubuchwepheshe, imithi, futhi izinhlelo.

Ekugcineni, bonke abantu bangathanda ukuhamba kwamandla zesimiso sonozungezilanga. Futhi iplanethi Gliese 581d uphelele uya khona. It uhlala kuphela ukuhlela ukuvakashelwa lalinamaJuda. Mhlawumbe lokhu kungenziwa uma ososayensi namanje ukuqopha isignali eyamukelwe.
