... The collecting area is increased by nesting concentric mirror pairs, all having the same focal length. ... Figure shows the largest optical element being ground at HDOS. ... X-ray testing demonstrated that the CXO mirrors are indeed the largest high-resolution X-ray optics ever made; the nominal effective area (based on the ground calibrations) is shown as a function of energy in the left panel of Figure , along with those of their Einstein and ROSAT predecessors. ...

. Computer Ephemeris for 2016 from DE200/LE200. Map of the Lunar eclipse - 18 Aug 2016. There is mercator global map of the world with eclipse lines on it. Legend: Curved lines are for eclipse limits in the horizon red line is for semishadow eclipse, blue line is for shadow eclipse, yellow line is for total eclipse. Straight line connects the sub-Lunar points during the eclipse (sorry, but it's yellow too).

... The author of the cover picture is Vasilisa Verkhodanova. The picture symbolizes our perception of the world. The modified emblem of the SAO unifying the 6-m optical telescope and the raditelescope RATAN-600 of SAO RAS is placed in the center of the radio galaxy isophotes. From the one hand, we can investigate the properties of radio galaxies with these (and other) telescopes, and try to study physical processes providing their activity. ...

An atom is the smallest "piece" of an element that still has the properties of that element. For example, an atom of gold is the smallest piece of gold that still acts like gold ? ... When many atoms come together, atoms tend to form molecules. A molecule is a combination of two or more atoms bonded together. For example, a molecule of water (designated by the symbol H 2 O) consists of two hydrogen atoms and an oxygen atom which are in a "relationship" ? ...

Authors: Yu.G. Shevelev , V.A. Marsakov , . ... We have constructed and investigated properties of metallicity function of disk stars with different ages, proceeding from the statistically restored real altitude distributions of stars at the solar galactocentric distance. It is shown that the metallicity distribution of stars in each age range is not of Gaussian form, but it may be considered as a superposition of two normal distributions centered at -0.2 and 0.0 dex. ...

... Indeed, in a number of cases, when studying the motion of celestial objects one should take into account both gravity and repulsive force of light pressure. ... For the first time it was V. V. Radziewsky who stated and solved some prob­ lems in dynamics of particle's of the photogravitational problem. In the pho­ togravitational three--body problem, formulated by him, in contrast to the clas­ sical problem, one of primaries or both of them are the sources of light repulsion. ...
