[1]Subaru Telescope bụ 8.2-meter (320 in) telescope National Astronomical Observatory nke Japan, nke dị na Mauna Kea Observatory na Hawaii. A na-akpọ ya aha kpakpando mepere emepe nke a maara na Bekee dị ka Pleiades. O nwere enyo kachasị ukwuu n'ụwa site na ntinye ya ruo n'afọ 2005.

Nchịkọta[dezie | dezie ebe o si]

Subaru Telescope bụ telivishọn Ritchey-Chretien na-egosipụta. Enwere ike itinye ngwá ọrụ [2] Cassegrain focus n'okpuru enyo isi; na nke ọ bụla n'ime ebe abụọ Nasmith focus n'ime ogige dị n'akụkụ ugwu telivishọn, nke a pụrụ iji enyo nke atọ duzie ìhè; ma ọ bụ na isi ihe n'ọnọdụ enyo nke abụọ, ndokwa a na-adịghị ahụkebe na nnukwu telivishons, iji nye ohere dị ukwuu maka nyocha dị omimi.

N'afọ 1984, Mahadum Tokyo guzobere otu ọrụ injinia iji mepụta ma mụọ echiche telivishọn 7.5-meter (300 in). N'afọ 1985, kọmitii na-ahụ maka mbara igwe nke kansụl sayensị nke Japan nyere ihe kachasị mkpa maka mmepe nke "Japan National Large Telescope" (JNLT), na 1986, Mahadum Tokyo bịanyere aka na nkwekọrịta na Mahadum Hawaii iji wuo telivishọn na Hawaii. 'afọ 1988, e guzobere National Astronomical Observatory nke Japan site na nhazi nke Tokyo Astronomical observatory nke Mahadum ahụ, iji lekọta JNLT na nnukwu ọrụ ndị ọzọ nke mba.

Iwu nke telivishọn Subaru malitere n'ọnwa Eprel afọ 1991, ma ka e mesịrị n'afọ ahụ, asọmpi ọha na eze nyere telivishons aha ya, "Subaru Telescope". [3] wuchara ya n'afọ 1998, e wepụtakwara foto sayensị mbụ na Jenụwarị 1999. [4] Septemba 1999, Princess Sayako nke Japan raara onyokomita ahụ nye.

A rụrụ ọtụtụ teknụzụ ọkaibe n'ime imewe telivishọn. Dịka ọmụmaatụ, ndị na-arụ ọrụ 261 na-achịkwa kọmputa na-agbanye enyo isi site n'okpuru, nke na-edozi maka mgbagwoju anya enyo isi nke mgbanwe na ntụziaka telivishọn kpatara. A na-ahazi ụlọ oghere teliskop ahụ iji melite ogo nke ihe oyiyi mbara igwe site na ibelata mmetụta nke ikuku ikuku na-akpata.

Subaru bụ otu n'ime telivishọn ole na ole dị elu nke ejirila anya nkịtị mee ihe. Maka nraranye ahụ, e wuru ihe anya ka Princess Sayako wee nwee ike ile ya anya. Ndị ọrụ ahụ nwere obi ụtọ ya ruo abalị ole na ole ruo mgbe ejiri ngwá ọrụ na-arụ ọrụ dochie ya.

Subaru bụ ngwá ọrụ bụ isi na ọchụchọ maka Planet Nine. Nnukwu ebe a na-ahụ ya, okpukpu 75 karịa nke telivishọn Keck, na ike na-achịkọta ìhè dị ike maka nyocha mbara igwe miri emi.

Ihe abụọ dị iche iche gburu ndụ ndị ọrụ anọ n'oge a na-ewu telivishọn ahụ. N'abalị iri na atọ n'ọnwa Ọktoba n'afọ 1993, Paul F. Lawrence dị afọ iri anọ na abụọ merụrụ ahụ nke ukwuu mgbe ihe na-adọkpụ ụgbọala kụrụ ya. Na Jenụwarị 16, 1996, ọkụ sitere na onye na-agbanye ọkụ kpaliri ihe mkpuchi nke na-ere ọkụ, na-emepụta anwụrụ ọkụ na-egbu egbu nke gburu Marvin Arruda, 52, Ricky Del Rosario, 38, na Warren K.

Coronagraph na-eji Phase Induced Amplitude Apodization (PIAA) imewe nke pụtara na ọ ga-enwe ike ise foto mbara ala ndị dị nso na kpakpando ha karịa ụdị ụdị coronagraph Lyot. ọmụmaatụ, n'ebe dị anya nke 100 pc, PIAA coronagraph na SCExAO ga-enwe ike iji foto site na 4 AU n'èzí ebe Gemini Planet Imager na VLT-SPHERE site na 12 AU n'elu. [17] ahụ nwekwara ọtụtụ ụdị coronagraph ndị ọzọ: Vortex, Four-Quadrant Phase Mask na 8-Octant Phase Mask versions, na coronagraf pupil. nke mbụ nke owuwu ahụ agwụla [1] na nke abụọ a ga-arụcha na ngwụcha afọ 2014 [2] maka ọrụ sayensị na 2015. SCExAO [18]-eji igwefoto HiCIAO mee ihe na mbụ mana CHARIS ga-eji nke a dochie anya, [1] ihe zuru oke na-ahụ maka ihe na-eme n'ọhịa, n'ihe dị ka afọ 2016.
