...normal luminosity. Many ideas for this variation in brilliance have been set forth by astronomers all over the country, but few of them seem to give any valid reason for it. Whipple stated that one of the more feasible is that there may be a great cloud of meteor dust, not unlike that which surrounds Saturn, through which the comet is at present passing; and it is the gases that are emitted by this cloud which unite with the comet and produce a reflection of unusual brillianey, a light which is made brighter by the presence of the sun. Another...
...Leonid meteor spectra, which the Observatory has obtained, are the first spectra of this kind ever to have been photographed. With the new photographs, the staff of the Observatory hopes to be able to study the conditions under which Leonid meteoric radiation is produced...
...plates of Leonid meteor spectra and one direct photograph of a leonid have been obtained to date from the observations made by members of the staff and students of the Harvard Observatory on the nights of Monday, Tuesday, and Thursday, November...
...well observed, he gives a preliminary value of 500 million years, which is probably a minimum value because of possible loss of helium in space and in our museums for over 60 years. The Pultusk meteorite was certainly of interstellar origin, and judging from preliminary results of the Arizona meteor expedition, we may expect that at least several of the iron meteorites investigated by Paneth also do not belong to the solar system...
Despite the fact that there is no authorized record of a man being killed by a meteor, such a shower bombarded the earth at a desolate spot in Siberia in 1909 that wild life has not yet returned. Within a radius of 300 miles from the point where the meteor struck trees were blown down by force of the air pressure. The fall was recorded as an earthquake disturbance on the seismograph at the University of Moscow and even on the Ferdham University instrument...
