Telescope buru oke ibu
Igwe onyonyo dị oke egwu ( ELT ) bụ ụlọ nke mbara igwe nke a na-arụ. Mgbe emechara ya, ọ ga-abụ teliskop ngwa anya / infrared kacha ukwuu n'ụwa. akwụkwọ nke ụlọ ọrụ European Southern Observatory (ESO), ọ dị n'elu Cerro Armazones na Desert Atacama nke ugwu Chile .
[1]Nhazi ahụ nwere teliskop na- akara enyo nwere 39.3-metre-diameter (130-foot) na enyo bụ 4.2 m (14 ft) dayameta nke abụọ mirror. A ga-akwado teliskop ahụ site na ngwa ihe ngbanwe, ndị njikwa ndu laser isii, yana ọtụtụ ngwa ngwa. [1] [2] Nhazi nke ụlọ ahụ ga-achịkọta ìhè 100 nde mmadụ anya, nke ya na ihe dị ka okpukpu iri ìhè teliskop kacha ibu dị ka nke 2023, ọ ga-edozikwa mgbagha ikuku. O nwere ihe dị ka okpukpu 250 mpaghara mkpokọta ọkụ nke Hubble Space Telescope yana, dịkapụta ELT siri dị, ga-enye ngosi ugboro iri na isi nke sitere na Hubble.
[2] [3]Na 11 June 2012, ESO Council mmemme mmemme ELT ibido ọrụ obodo na saịtị teliskop, na ọrụ teliskop n'onwe ya na-echere echere ikpeazụ ya na ike nke ụfọdụ mba ndị otu. Ụbọchị owuwu na saịtị ELT mgbasa na June 2014. Ka ọ na-erule December 2014, ESO enwetala ihe ọmụmụ 90% nke mkpokọta ego yana ikike, teliskop ka ụzọ, nke ga-efu ihe ruru otu ụdị euro maka usoro ihe owuwu nke mbụ mbụ. . Nkume mbụ nke teliskop ahụ bụ nke edobere emume na Mee 26, 2017, na-ebido wuo ihe owuwu na teliskop bụ isi dome. [1] Teliskop ahụ, ọkara ụzọ n'ime kpọmkwem na owuwu ya na Julaị 2023, yana mmecha na ọkụ mbụ e mere akwụkwọ maka 2028
[4]Na 26 na 2010, European Southern Observatory (ESO) Council Cerro Armazones, Chile, dị ka ebe ntọala maka ELT zubere. Ebe ndị ọzọ a na-akpa ụka ụka Cerro Macon, Salta, na Argentina; Roque de los Muchachos Observatory, na Canary Islands; na saịtị dị na North Africa, Morocco, na Antarctica
Nhazi mbụ gụnyere enyo bụ isi nke kewara nke nwere dayameta 42 metres (140 feet) na mpaghara dị ihe dịka 1,300 m , nke nwere enyo nke abụọ nwere dayameta nke 5.9 m (19 ft) . Agbanyeghị, n'afọ 2011, etinyere atụmatụ iji belata nha n'ozuzu ya site na 13% ruo 978. m 2, ya na 39.3 m (130 ft) mirror isi dayameta na 4.2 m (14 ft) dayameta nke abụọ mirror. [5] Nke a belatara ọnụ ahịa a tụrụ anya ya site na ijeri 1.275 ruo ijeri euro 1.055 ma kwesị ikwe ka emechaa teliskop ahụ ngwa ngwa. Obere nke abụọ bụ mgbanwe dị mkpa karịsịa; 4.2 m (14 ft) na-etinye ya n'ime ikike nke ọtụtụ ndị na-emepụta ihe, na nkeji enyo dị ọkụ na-ezere mkpa maka ihe ndị dị elu na-akwado ududo nke abụọ. : 15
Onye isi oche ESO kwuru na nkwupụta mgbasa ozi 2011 na "Site n'ichepụta E-ELT ọhụrụ anyị ka nwere ike imeju ebumnuche sayensị siri ike ma hụ na a ga-arụcha ihe owuwu ahụ n'ime naanị afọ 10-11." [6] Kansụl ESO kwadoro nhazi usoro ntọala edegharịrị na June 2011 wee tụọ anya n'atụmatụ ihe owuwu maka nkwado na Disemba 2011. [6] E mechara tinye ego na mmefu ego 2012 maka ọrụ mbụ ịmalite na mbido 2012. [7] Ọrụ a nwetara nkwado izizi na June 2012. ESO kwadoro mmalite nke owuwu na Disemba 2014, na-enweta ego karịrị 90% nke mmefu ego n'aha.
