... All the galaxies are divided into 4 groups depending on the environment type; every subsample contains more than 10 galaxies. ... An effect of environments is seen both for the nuclei and for the bulges: if we consider the clusters (Virgo and Ursa Ma jor) and group centers as dense environments and the field and group periphery as sparse environments, then in the dense environments the stellar populations of S0s are in average older by 45 Gyr than in the sparse ones. ...

Launched on February 17, 1996, the Near Earth Asteroid Rendezvous (NEAR) mission is to be the first of NASA's Discovery missions, a series of small-scale spacecraft designed to proceed from development to flight in under three years for a cost of less than $150 million. ... The ultimate goal of the mission is to rendezvous with and achieve orbit around the near Earth asteroid 433 Eros in February, 1999, and study the asteroid for approximately one year. ...

... For a semple of red giants comprising about 2000 stars, the distributions of metallicity [Fe/H] are given. ... The center of the distributions of giants in both galactic poles is found to demonstate a statisticaly significant gap similar to the one found earlier for the late main-sequence stars. The implications of the metallicity distribution properties for the problems of the chemical evolution of the galactic disk are discussed. ...
... Захаров А. Ф. It is generally accepted now that there is a supermassive black hole at the Galactic Center. ... Observations of trajectories of bright stars at the Galactic Center in IR band have been done with an enormous precision. ... We review theoretical studies and their links with observations to get constraints on parameters of the Galactic Center potential and as a result to evaluate parameters of the black hole and distributions of stellar cluster and dark matter near the black hole. ...

... Under certain conditions, like those in the nucleus of a QSO, all atoms can be made to emit light at particular wavelengths. ... If that source is approaching the observer, the wave is squashed up onto itself making the wavelength shorter. ... This is redshift. ... You can see how the section of the QSO spectrum which we observe changes with redshift. ... We then see how far we had to slide the observed spectrum along the scale to make it match and that is the objects redshift. ... The 2QZ team . ...
