... It does not seem a far-fetched notion.The Soviet Union began the Space Age with an early lead over the Americans.The first satellite in orbit, first man in space, first spacewalk and first probes to the Moon were all achieved by the USSR.In 1967, NASAтАЩs Apollo project appeared to be faltering following the deaths of three astronauts in an accident which had indicated fatal flaws in the spacecraft design. ... The moon project was led by Sergei Korolev, architect of the early Soviet space successes....

This is the first time that a quasar outflow has been measured to have the sort of high energies predicted by theory. ... Quasars are the intensely luminous centers of distant galaxies that are powered by huge black holes. ...

In recent years the spectrum of observed astronomical data can be characterized as greatly varied. ... In this instance, the problem of initial description and classification of newly-observed data becomes most urgent, especially if there is a lack of preliminary observational material and theoretical expectations. ...

... The spectrum of the brightest star, our Sun, shows several dark gaps perpendicular to the flow of it’s colours (figure 1). These so called spectral absorption lines where discovered in 1802 by the English scientist William Wollaston. ... Some stars as Pollux show a spectrum similar to that of our sun with strong Ca II and Fe II lines, others as Sirius or Vega show strong absorption lines of hydrogen, others, as Mira show very complicated spectra due to molecular absorption lines (see figure 5). ...

An accuracy estimation of CCD asteroid observations contained in the Minor Planet Center Database and carried out in the years 1999 - 2006 is realized. About 20 millions individual positions of the Numbered and Unnumbered Minor Planets were tested by means of calculations of (O-C) residuals to derive "mean error of a single observation" for more than 400
