. The Gemini. The Gemini is a zodiak constellation. The stars Castor and Pollucs presents the twins' heads and theeir bodies lead down to the Mylky Way, to the Orion side. The Greeks called the stars so, because Castor and Pollucs were the names of Zevs sons. Castor is a visible triple system and its both bright components are the double stars and the weak one is an eclipsed double system. So Castor is a multiple system of the six stars. Back .

... The author attempts to approach the problem from the positions of systems analysis with account for the ideological grounds and history of space activities in Russia and abroad, comparing its current interpretation with the initial goals posed by leading theoreticians and practitioners who stood at the cradle of the space exploration era. ... The space systems recognized in Russia as priority projects are largely developed with violations of the systems approach principles. ...

... 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). ...
