... About meteorites . ... Meteoritic data . ... About laboratory . ... The lake is like a round mirror 200 meters in diameter, surrounded by a ring wall 350-400 meters across. ... The ring wall, especially well preserved along the southeast shore of the lake, the steep banks and the great depth, all indicated that at one time there had been a powerful explosion here. ... It is possible that the depth may have been 40 meters before but that the slumping of the banks was helping to decrease the depth. ...

... Spacecraft that will search for planetary systems around 40 million stars and observe the largest explosions in the universe have been chosen as the next two missions in NASA's medium-class Explorer (MIDEX) program. ... The first mission, to be launched in 2003, is the Swift Gamma Ray Burst Explorer, a three-telescope space observatory for studying gamma ray bursts. ... During its three-year mission, Swift will also survey the sky for new black holes and other sources of cosmic gamma rays. ...

The 2dF QSO Redshift Survey (2QZ) . ... Before jumping into all the finer details of teh survey, a brief non-astronomer's guide to redshift surveys is available. ... The primary scientific aims of the QSO survey are: (1) to obtain the primordial fluctuation power spectrum out to COBE scales, (2) to determine the rate of QSO clustering evolution in the non-linear and linear regimes and hence obtain new limits on the value of and the bias parameter, (3) to apply a powerful geometric method to measure . ...

ПЛАНЕТА ОЗИРИС . ... Озирис оказался первой экзопланетой, которая была исследована как с помощью метода доплеровской спектроскопии, когда измеряются небольшие смещения линий в спектре звезды, вызванные гравитационным влиянием планеты, так и с помощью наблюдения т.н. транзитов, т.е. проходов планеты по диску звезды. ...

... A nasty dispute between the Strategic Defense Initiative Organization (SDIO) and the space-science community was narrowly averted early this year when SDI officials backed down on a planned launch of a satellite with a Russian-built nuclear reactor on board. ... Early Soviet space reactors orbited for two to three months, and two Soviet Topaz 1 experiments, one for six and one 12 months, created radiation belts that disrupted the operation of scientific satellites. ...

Absolute magnitudes, metallicities, effective temperatures, surface gravities, distances, and tangential velocities are calculated for 5498 F stars with homogeneous data on uvby photometry and proper motion, and placed within 80 pc from the Sun. Components of space velocities, eccentricities of galactic orbits, perigalactic and apogalactic distances, and maximal remotness from galactic plane are presented for 1787 stars. ...
