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 .

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.

 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

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.  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."  Kansụl ESO kwadoro nhazi usoro ntọala edegharịrị na June 2011 wee tụọ anya n'atụmatụ ihe owuwu maka nkwado na Disemba 2011.  E mechara tinye ego na mmefu ego 2012 maka ọrụ mbụ ịmalite na mbido 2012.  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.
