[漢羅] 3 台 輔助望遠鏡 AT

就算 in kah R2D2 機器人足成--ê，這 3 台並毋是你欲揣 ê 機器人。 顛倒是，這个外殼內底裝 ê 是直徑 1.8 公尺大 ê 輔助望遠鏡 AT (ATs)，是 智利 Atacama 沙漠 地區 Paranal 天文台 ê 望遠鏡。 AT 望遠鏡是設計欲來 做干涉儀用--ê，這是一款 kah 8 公尺大 ê VLA 望遠鏡 配合 ê 懸解析度觀測技術。 遮攏總有 4 台 AT 當咧運作，逐台下底攏鬥一台車仔，通予望遠鏡會當 tī 鐵枝路頂懸 徙來徙去，組合做無仝 ê 排列，鬥做一个較大單位 ê 望遠鏡。 為著欲當做干涉儀使用，逐台望遠鏡接收著 ê 光線會送去 tī 地下道 ê 反射鏡系統 ê 共同焦點。 這 3 台 AT 天頂有 大麥哲倫星雲 kah 小 麥哲倫星雲，in 兩个攏是咱銀河系 ê 衛星星系，毋閣有較遠淡薄仔。 Tī 南半球好天暗暝 ê 天頂，咱會當看著地球大氣 ê 青色 氣輝，綴地平線頂懸 微微仔咧發光。

[English] 3 ATs

Despite their resemblance to R2D2, these three are not the droids you're looking for. Instead, the enclosures house 1.8 meter Auxiliary Telescopes (ATs) at Paranal Observatory in the Atacama Desert region of Chile. The ATs are designed to be used for interferometry, a technique for achieving extremely high resolution observations, in concert with the observatory's 8 meter Very Large Telescope units. A total of four ATs are operational, each fitted with a transporter that moves the telescope along a track allowing different arrays with the large unit telescopes. To work as an interferometer, the light from each telescope is brought to a common focal point by a system of mirrors in underground tunnels. Above these three ATs, the Large and Small Magellanic Clouds are the far, far away satellite galaxies of our own Milky Way. In the clear and otherwise dark southern skies, planet Earth's greenish atmospheric airglow stretches faintly along the horizon.
