RUSSIAN . The Centre for Astronomical Data (CAD) of the Institute of Astronomy (INASAN) of the Russian Academy of Sciences was established in 1980 as a branch regional center of the Centre de Donnes Stellaire (CDS) with the purpose of astronomical data dissemination among Soviet and Eastern Europe astronomers and for providing the CDS with Soviet machine readable astronomical catalogues. The CAD archive is based on astronomical catalogues received from Strasbourg since 1980. ...
... We found that 10 metal-poor globular clusters are greately distinguished for anomalously small masses on the "destruction rate-mass" plain. As it turned out, these poor clusters, situated 15 kpc farther from the Galactic centre, are somewhat younger than the bulk of the metal-poor globulars, and have anomalously red horizontal branches. ... At the same time, deficiency of distant massive clusters is noticeable with increasing distance from the galactic centre. ...

... In 1497 he moved to Rome, where he observed a lunar eclipse and gave lectures on astronomy and mathematics. "the Solar System was believed to have the Earth for the centre with the planets and Sun going around it" Copernicus came up with a theory called the Heliocentric hypothesis. For centuries the Solar System was believed to have the Earth at its centre with the planets, Moon and Sun moving around it. ... Copernicus wrote a short piece on his theory called `De Revolutionibus'. ...

The small variations in distance to the individual Cepheid variable stars in the Cloud are negligible compared with the much larger distance to the SMC. ... In this way Cepheid variable stars can be used as one of the 'standard candles' in the Universe that act either as distance indicators themselves or can be used to calibrate (or set the zero point for) other distance indicators. ...

Hipparchus (and possibly Aristarchus before him) also derived the Moon's distance from the duration of a lunar eclipse . Because the Earth casts a much larger shadow than the Moon, such an eclipse usually darkens the entire Moon, for several hours. ... If the Sun is assumed to be very distant, and if the Moon crosses the middle of the shadow (if not, corrections must be made), the width of the shadow is expected to be about 2r , twice the Earth's radius r . ...
