火星的诱惑

火星的梦想数千年以来,天空中这颗红色的明亮星星就一直令人着迷。在古希腊人和古罗马人的神话中,火星(Mars)是战神的名字,这或许与它那红色的光芒有关。十九世纪七十年代后期,意大利天文学家斯基帕雷利(Giovannl Schiaparelli)从天文望远镜中看到了火星上有"河道"(canali)。河道一词被翻译成英语时变成了"运河"(canal),这个误     

业余设备摄星空

对业余天文爱好者来说，最令他们激动的事情莫过于第一次看到遥远的星空中那些不可思议的景观了。例如漂浮在漆黑夜幕中的土星、远方星系的碰撞等。然而长期以来，这些壮丽的景观只有那些拥有精良装备的天文爱好者才能拍摄到，这是因为要想拍摄那些夜空中微弱的星光，就必须使用价格非常昂贵的高灵敏度照相机和天文望远镜才行。

地球人口突破70亿大关法国国家人口研究所的最新研究报告显示,地球人口自1800年以来已经增长7倍,现在已经突破70亿大关。估计到下世纪初,地球人口能够稳定在90亿到100亿左右。该研究报告指出,1999年地球人口超过60亿,而2011年这个数字已经超过70亿,在短短十多年内地球人口增加了10亿。虽然目前地球人口增长幅度逐渐趋缓,但趋缓的程度十分有限,据估计,2025年时地球人口将达到80亿     

Large Astronomical Telescope Development in China:Achievements and Prospects

LAMOST represents a brand-new concept for telescope design and development.—CAS Member SU Dingqiang We are taking the lead in some aspects,including large-scale spectral sky survey,active optics and positioning of optical fibers.—CAS Member CUl Xiangqun From the point of view of an opticist,the Large Sky Area Multi-Object Fiber Spectroscopic Telescope(LAMOST) marks a miracle-like milestone.It integrates a lot of innovative ideas once thought to be impossible:both the primary mirror     

Large Sky Area Multi-Object Fiber Spectroscopic Telescope

The Large Sky Area Multi-Object Fiber Spectroscopic Telescope(LAMOST) is a meridian reflecting Schmidt telescope with a clear aperture of four meters,a focal length of 20 meters and a field of view of five degrees.By using active optics technique to control its reflecting corrector,
