21 December 2009: Telescope Domes Clustered at La Silla
2009.12.21：拉斯拉天文台的望远镜圆顶群
This view of ESO’s La Silla Observatory reveals the splendour of the night sky and shows several of the domed telescopes located at the site. The glowing band of the plane of the Milky Way Galaxy slants through the sky from the upper left to the lower middle, where the Danish 1.54-metre telescope looms in the foreground. The ghostly, bluish objects above the telescope’s dome are two galaxies belonging to the Milky Way’s close neighbourhood and known as the Large and Small Magellanic Clouds.
本图展示了辉煌的南天夜空下，ESO的拉斯拉天文台的多个望远镜圆顶。从左上延伸到天空中下方的发光彩带是我们的银河系，它隐没在图中前景：1.54米丹麦望远镜后。空中两个发蓝的幽灵般天体是我们熟知的银河系的两个邻居：大、小麦哲伦星系（LMC、SMC）。
La Silla’s collection of domed telescopes also includes the ESO 3.6-metre telescope, home to HARPS (High Accuracy Radial velocity Planet Searcher), the world’s foremost exoplanet hunter, and the 3.58-metre New Technology Telescope, which broke new ground for telescope engineering and design, and was the first in the world to have a computer-controlled main mirror (active optics), a technology developed at ESO and now applied to most of the world’s current large telescopes. La Silla is one of the most scientifically productive ground-based facilities in the world after ESO’s Very Large Telescope (VLT) observatory, both of which are located in northern Chile’s Atacama Desert.
拉斯拉天文台的圆顶望远镜还包括：3.6米ESO望远镜，其中安装了全球最著名的系外行星猎手：高精度径向速度法行星搜索仪（HARPS）；3.58米的新技术望远镜（NTT），它创立了望远镜工程设计的新水准：它的主镜由计算机实时控制（主动光学技术），这项由ESO首创的技术现已应用于世上大部分的大型望远镜中。拉斯拉天文台是世界上科学发现最多的地面天文台之一，仅次于ESO的甚大望远镜（VLT）群，两者都位于智利北部的阿塔卡马沙漠地区。
