世界最大电波望远镜在智利阿塔卡马沙漠一座高山上开始投入使用,Alma项目包括66个巨型天线,有望提供前所未有的信息,帮助我们理解宇宙的起源。工作于该项目的瑞士天文学家Andreas Lundgren解释了该电波望远镜与传统光学望远镜相比的优势。
"The radio waves, they can penetrate into these black clouds to understand star formation. Optical telescopes, they can just see the surface while we can see what’s actually going on inside the cloud. Alma is bigger than all the other telescopes combined, was so much more sensitive and we are just still growing to disguise the limit.”
“无线电波可以穿过浓云来探明星状组合,光学望远镜只能看到表面,而电波望远镜可以看到云的内部,Alma比所有其他望远镜加在一起都要大,但也更容易受损,所以我们在努力改善其限制。”
The authorities in Venezuela have extended the official mourning of the late president Hugo Chavez until Friday. The decision means that official buildings will continue to fly their flags at half-mast and celebrations and festivities will remain banned. Mr Chavez died last Tuesday after a long battle against cancer.
