... Space Flight . ... The Future . ... Just as the colour and style of a police officerтАЩs uniform may vary depending on their nationality or current circumstances, so the same can be said of the different spacesuits that men and women have worn to head into space. ... Slung-shot far above the 100km mark, Alan Shepard, the first American astronaut to enter space wore the Mercury Program spacesuit in May 1961. ...

... Using the uvby -photometry and proper motion data for about 5500 F stars within 80 pc from the Sun, we have studied velocity ellipsoid parameters and obtained the following results. 1) The sizw of all wllipsoid semiaxes increase systematically for groups of stars with the decrease of both temperature (at constant metallicity) and metallicity (at constant temperature). ... As a result, each of the three parameters - temperature, metallicity and velocity dispersion - is an age indicator. ...
We have designed the laboratory model of static Fourier spectrometer for onboard usage for spectral study of atmosphere and ionosphere. The gain of model is to simulate onboard FS which will not have any moving elements (all its optical elements will be mounted at fused quartz monolithic construction), to compare experimental results with theoretical estimations and to measure MTF of CCD array. ... This fact connected with low frequency response of CCD array due to small format of it. ...

... Bad Astronomy . ... Bad Astronomy : The Moon appears larger on the horizon than overhead because you are comparing it to foreground objects. Good astronomy : The Moon does appear larger on the horizon, but it is because of the way we perceive the sky. ... The most common misconception is that it is because you are unconsciously comparing the Moon to foreground objects like trees and houses, or even the horizon itself, and that makes the Moon look bigger than when it is all alone in the sky. ...
The Archeops experiment aimed at measuring the cosmic background emitted just after the Big Bang. The study of this radiation is essential to obtain precise information on the evolution of the Universe: density, Hubble constant, age of the Universe.. To achieve this goal, measurements have been done with devices cooled down at 100mK temperature placed at the focus of a warm telescope. ... 28960 visitors . ...

... 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. ...
