The first Russian robot-telescope MASTER was developed in 2002 and installed nearby Moscow. ... OAO MO "Optica" has mastered the production of such systems. The workshop is devoted to the results achieved by MASTER-net, that recently stretch over the globe from Blagoveshensk to Argentina. ...

... He made observations of a supernova (literally: nova= "new star") in 1572 (we now know that a supernova is an exploding star, not a new star). ... Brahe's meticulous observations showed that the supernova did not change positions with respect to the other stars (no parallax). ... This was early evidence against the immutable nature of the heavens, although Brahe did not interpret the absence of parallax for stars correctly, as we discuss below. Brahe made careful observations of a comet in 1577. ...

... While there is practically no detector noise present at energies above , X-ray data below are considerably contaminated by noise events, which become more and more dominant towards the lowest transmitted energies (Fig. ... Investigations of 40 hours of in-orbit calibration data with the filter wheel closed, taken over a period of more than two years, showed that the noise properties vary with position and energy, but are fairly stable in time for most areas on the detector. ...

Abstract -- Calculations are performed for the linear polarization of starlight due to extinction by aligned dust grains when the starlight traverses a medium with irregular magnetic fields. This medium is intended to represent the optically thick components of interstellar clouds which are observed to make little, if any, contribution to the polarization of starlight. ...

The infrared satellite IRAS. The main task of the IRAS telescope was the search of a longwave infrared radiation, composing the maps of the sky in the infrared range. IRAS telescope helped to discover new galaxies, to study the properties of the dust particles in our galaxy, which opens the character of a star hiding somewhere in the sky. ... For 6 months of observation it discovered 6 new asteroids, allowed to find out the nature of the dust zones between Mars and Jupiter orbits. ...

... We present Very Large Array observations of the intermediate mass pre-main-sequence stars UX Ori and CQ Tau at 7mm, 3.6cm, and 6cm. ... Both stars are detected at 7mm but not at longer wavelengths, which confirms that the millimeter emission is dominated by dust. ... The observations do not spatially resolve the 7mm emission. ... The CQ Tau system exhibits a spectral index in the millimeter range of alpha_mm~2.6, consistent with values commonly found for disks around pre-main-sequence stars. ...

... Planets . ... Exoplanets . ... After the discovery of powerful telescopes we were able to see further into our Solar System and discover many distant objects and dwarf planets.€а However within the last 16 years astronomers have started to dedicate much more time to the search of other worlds in orbit around other stars beyond the realm of our Solar System. ... However the closest star with a known exoplanet is the star Epsilon Eridani which is a mere 10.4 light years away from planet Earth. ...
