Astronomers Put Forward New Theory of Galaxy Formation

How and when did galaxies form? How and when did stars form in these island-like universes? These questions are still posing a considerable challenge to present-day astronomers.     

CAS Astronomers Find Chromospheric Apparent Fan-shaped Jets Nearby Sunspots

<正>Using high-quality Hα observations from the New Vacuum Solar Telescope(NVST), Dr. LI Ting from the National Astronomical Observatories of the Chinese Academy of Sciences(NAOC) and partners first report apparent fan-shaped jets generated during the interaction between primary fan-shaped jets and nearby facula magnetic structure.     

Chinese Astronomers Created an Empirical Stellar Spectra Library from LAMOST

Chinese and Japanese Astronomers Discover the Most Lithium-rich Stars

正Big Bang Nucleosynthesis(BBN)has produced three light elements:hydrogen,nitrogen and lithium.Measuring the abundances of these elements is the most reliable way to explore the physical condition in the first few seconds after the BBN.Recently,using LAMOST data and follow-up observations,the stellar abundance group at the National Astronomical Observatories of the Chinese Academy     

Chinese Astronomers Identify Nitrogen-Enhanced Field Stars in LAMOST DR3

正As a bar-spiral galaxy, our Milky Way (MW)is quite active chemically and dynamically.Among our MW stars, is it possible to know the evolution of each star, in order to accurately study the MW formation and evolution? Recently, chemodynamics scholars try to understand the stellar and MW evolution

New Clues Achieved by CAS Astronomers in Their ET Research

CAS astronomer recentlymade significant progress insearch of Earth-like planetsoutside our own solar system.The quest of an extra-terres-trial (ET) civilization is a time-hon-ored endeavor. As a research topic,it could be traced back to 2,400 yearsago when Aristotle (384 322BC)forwarded the philosophicalproposition: Is our human race re-ally solitary in the universe?Since 1955, via the detectionmethods of radial velocity and oc-cultation of planets in the wake ofthe burgeoning development…

卸装后的牛顿读怀特的《最后的炼金术士--牛顿传》

牛顿(Issac Newton,1643-1727)无疑是人们最熟悉的一位伟大的科学家,也许比20世纪最伟大的物理学家爱因斯坦(AlbertEinstein,1879 1955)更广为人知.“牛顿苹果“的故事,几乎是无人不知无人不晓.但是人们对于牛顿有多少正确的了解,恐怕就很难说了.由于最初的几位牛顿传记作者,如第一位给牛顿写传记的英国作者斯图克利(William Stukeley,1687-1765)和另一位重要传记作者布鲁斯特爵士(SirDavidBrewster,178l-1868,也是英国人),都是“近距离“仰视牛顿,免不了因过度崇拜而造成偏见,把牛顿看成是一个半人半神、没有丝毫缺点的人.由此就必然会使这些作者在为牛顿写传时缺乏客观性,凡遇到与他们心目中不相符合的资料或证据时,他们都本能地故意漠视,精心地删去.正如英国传记作家迈克尔&#183;怀特(MichelWhite)在其&lt;最后的炼金术士:牛顿传&gt;(Issac Newton:The Last Sorcerer,1997)中所言:……     

牛顿其人

当我试图在牛顿自己的家中向你们讲述牛顿的真实形象，我确实有些怯意。很长时间以来，我一直埋首于牛顿的手稿之中；我早就打算将我的印象和心得写成一篇文稿，在1942年圣诞节牛顿诞辰300周年纪念会议上宣读。但战争剥夺了我来探
