世界上最大的光学望远镜 — — ELT — — 正在智利建造,将于2029年开始运行,研究外行星、星系和暗物质。 The world’s largest optical telescope, the ELT, is being built in Chile and will begin operations in 2029, studying exoplanets, galaxies, and dark matter.

欧洲南方天文台极大型望远镜(ELT)是世界上最大的光学望远镜,目前正在智利的Cerro Armazones山上建造。 The European Southern Observatory’s Extremely Large Telescope (ELT), the world’s largest optical telescope, is under construction on Chile’s Cerro Armazones mountain. 使用39米长的初级镜和先进的适应性光学,它将产生比哈勃更清晰15倍的图像。 With a 39-meter primary mirror and advanced adaptive optics, it will produce images 15 times sharper than Hubble’s. ELT定于2029年初进行首次技术照明,到2030年12月全面科学运行,它将研究外行星、早期星系、暗能、暗物质、恒星和黑洞形成。 Scheduled for technical first light in early 2029 and full scientific operations by December 2030, the ELT will study exoplanets, early galaxies, dark energy, dark matter, and star and black hole formation.
