THE CHEMICAL COMPOSITION OF REGOLITH AT THE MOON'S SOUTH POLE, ACCORDING TO DATA OF LUNAR PROSPECTOR AND LUNAR RECONNAISSANCE ORBITER MISSIONS. ... Introduction: The article tells about the results of integrated study of the craters at the Moon's South Pole with permanently shadowed region of craters. ... We have compared the ultimate composition of the soil matters in the craters with "cold traps" in the Moon's South Pole with regard to thorium, ferric oxide and hydrogen contents (Fig. ...

... The body of photometric and astrometric data on stars in the Milky Way Galaxy has been growing very fast in recent years (Hipparcos/Tycho, OGLE-3, 2-Mass, DENIS, UCAC2, SDSS, RAVE, Pan Starrs, Hermes, ...) and at the time of the General Assembly the launch of ESAтАЩs Gaia mission, which will measure astrometric data of unprecedented precision for ~ 10 9 stars, will be less than three years away. ... Producing models and fitting them to the available data will involve complex software. ...

... Gaseous discs in NGC 252 and in NGC 4513 have decoupled kinematics, and the ionized gas of their rings is certainly excited by young stars. ... Two other, quite isolated S0 galaxies with the UV rings, IC 522 and NGC 446, demonstrate the shock-dominated gas excitation in the UV-detected rings, so their rings may probably have impact origin. ... NGC 4513. ... The UV rings in isolated galaxies IC 522 and NGC 446 may represent the consequences of central impact by a satellite from a highly inclined...
