Among the major discoveries of the year reported by the Harvard Observatory in this capacity of announcement agency for observatories in the Western Hemisphere, were Van Biesbroeck's finding of a star with the lowest known candle power; Luyten's finding of a pair of white super-dense dwarf stars; the discovery of comets by observers in Finland and New Zealand; and the discovery by Kuiper o fan atmosphere of methane and ammonia on Titan, the largest satellite of Saturn...
...survey of the solar neighborhood, Dr. Shapley said that Dr. Luyten of the University of Minnesota, using Harvard plates, has completed a very extensive study of star motions. "He has found in the south Southern sky eightyfive thousand stars that show motion with respect to their neighbors, and among this vast number of moving objects are undoubtedly many that are the dwarf asosciates...
...various commissions are Miss Adelaide Ames, on nebulae; Leon Campbell, on planets and variable stars; Dr. Shapley, on variable stars, telegraphic information, star distances, photometry, and nebulae; Dr. W. J. Fisher, on astronomical notations and meteors; Professor W. H. Pickering, on planets and lunar names, Dr. W. J. Luyten '24, on star distances and statistics; Professor E. S. King, photometry and double stars; Dr. A. J. Cannon, variable stars and spectra; D. B. Pickering, variable stars; Dr. C. H. Payne, spectra; Professor H. H. Plasket, spectra...
...describing this meteorite, Luyten reports, "The first impression that one gets of the meteor, seeing it from a distance, is not too overwhelming, but this changes when one gets close to it. It is an enormous block of metal, almost rectangular in shape, of dimensions nine by ten feet, and a thickness varying from two and a half to almost four feet. When first found only a small part protruded above the limestone; since then a pit has been dug all around it which shows the full extent of the meteor on all sides. On the northeastern side...
...remarkable feature of this meteor", continues Professor Luyten, "is that it felt cool, in spite of the tropical sun almost overhead, which made the surrounding limestone unpleasantly hot to touch. It is said that this meteor is not magnetic. The results of the chemical analysis show 17.42 per cent nickel and 81.29 per cent iron. This is an unusually high proportion of nickel. It is not surprising, therefore, that the meteor is extremely hard and especially tough. Investigation with a file led to the estimate that this nickel-iron alloy compares in hardness with the hardest steel used on railroads...
