Getting to Moscow from the airport: There are three international airports in Moscow: Sheremet'yevo , Domodedovo , and Vnukovo . All three are connected to Moscow through a high-speed railway, called Aeroexpress , with moderately priced tickets (320 rubles, approx. ... The point of arrival is a rail terminal, which is connected to a subway station: Byelorusskaya for Sheremet'yevo, Paveletskaya for Domodedovo, and Kievskaya for Vnukovo. The map of Moscow Metro (subway) is found in Wikipedia. ...

... The greater the distance, the smaller the parallax. ... That triangle has the same proportions as the much larger triangle ABC, and therefore, if the distance B'C to the thumb is 10 times the distance A'B' between the eyes, the distance AC to the far landmark is also 10 times the distance AB. ... The most distant objects our eyes can see are the stars, and they are very far indeed: light which moves at 300,000 kilometers (186,000 miles) per second, would take years, often many years, to reach them. ...

T he Siding Spring Survey (SSS) is a Near-Earth Object search program that utilises the 0.5-m Uppsala Schmidt Telescope at Siding Spring Observatory, N.S.W., Australia. ... The mission of the Siding Spring Survey is to contribute to the inventory of near-earth objects (NEOs), or more specifically, the potentially hazardous asteroids (PHAs) and comets (PHOs) that may pose a threat of impact and thus harm to civilization. ... Based on the CSS Mission page . ... Siding Spring Survey Main Page . ...

... The very first step after correcting bias, dark, and overscan is to find the edges of the slitlets. This is done by the command LOCATE/MOS . This command takes the central trace of a flat-field and detects the edges of the slitlet by simple threshold comparison. ... The offsets in dispersion direction between the slitlets will be read from the header of the flat-field frame for FORS data and stored in :xoffset . ... The actual flat-correction is then performed with COMPUTE/IMAGE . ...

This source is hiding behind our Galaxy at a distance of ~18 Mpc, located at a galactic latitide of 0 degrees. ... As we look towards longer wavelengths, 60 micron, to try and penetrate the Galactic Plane, we still see confusion from galactic sources. ... If the image seems some what confusing that is because the MOST is a continuum radio telescope and when it looks in the direction of our Galaxy it detects radiation from sources within our Galaxy and from sources that may lie behind our Galaxy. ...

... As is known, the observed distribution of massive stars in the direction of the Galactic center looks very peculiar: the vast majority of all massive stars are concentrated towards the central 1 pc or so (Genzel et al. ... In order to compare the observed distribution of X-ray sources in the Galactic center with what would be expected from the population synthesis computations, we have considered two hypothetical scenarios for the location of the starburst. ...
