Extremely Large Telescope Breaks Ground
This is Scientific American 60 seconds, Space. I'm Clara Moskowitz, got a minute?
High on a Chilean mountaintop, scientists have broken ground on what will be the world's largest telescopeCalled the European Extremely Large Telescope, or E-ELT, the observatory may even be sensitive enough to spot signs of extraterrestrial life on alien planets—if there is any, of course.
在智利山山顶，科学家们开始了一项伟大的新工程，他们要制作出世界上最大的望远镜。他们为这台望远镜起名为“欧洲超大望远镜”，简称“E-ELT" 。如果外太空真的有生命的存在，那么这台仪器将可以检测到生命信号 。
The E-ELT's gigantic 39-meter-wide primary mirror will capture 15 times more light than any existing optical telescope, and its images should be 16 times sharper than the Hubble Space Telescope's.这台宽为39米的大家伙，其主镜聚光能力是世界上现有最清晰的光学望远镜的15倍，形成的图片是哈勃望远镜的16倍。
That kind of view could reveal exoplanets changing color with the seasons, suggesting the presence of vegetation. The scope might also reveal planetary atmospheres with chemicals consistent with life, such as oxygen, ozone, carbon dioxide and methane.
The European Southern Observatory is building the telescope. On June 19th they blasted off the top of the Cerro Armazones mountain to create a plateau for the facility.该望远镜由欧洲南方天文台研制。本月19号，科学家将炸平孙斯山山顶，用来安放仪器 。
The 3,000-meter-high site offers incredibly clear skies with a minimum of atmosphere to distort the images. The huge construction project is set to finish in 2023. Then, just maybe, we'll catch a glimpse of the activities of any cosmic neighbors.
Thanks for the minute for the Scientific American 60 Seconds Tech, I'm Clara Moskowitz
1.break ground on开始做...动工
They will break ground on the new housing project next week.
The space shuttle had been scheduled to blast off at 04:38.
