In 2001, Westerbork observations of the disturbed galaxy named VV-29 (alias Arp-188, UGC-10214) showed that there is second smaller galaxy (named VV-29c) that appears behind the western side of the main body of the distorted galaxy. ... The galaxy was featured as the May 2, 2002 Astronomy Picture of the Day . ... When VV-29 had its 15 minutes of fame in May 2002, it appeared under the name "The Tadpole Galaxy," but based on the images above, we will always think of it as "The CHAINSAW"! ...

... 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. ...

... The search for distant objects which can be both galaxies and quasars is one of the most important problems of observational astrphysics, because it allows one to determine cosmological parameters connected with the time of appearence and evolution of stellar systems, large scale structure of the Universe. ... Radio galaxies are important objects to be studied because they are sources of infrared-optical-ultraviolet continuum, emission lines and continual radio emission. ...

This artistically modified image of the local galaxy Arp 220, captured by the Hubble Space Telescope, helps illustrate the Herschel results. The bright core of the galaxy, paired with an overlaid artist's impression of jets emanating from it, indicate that the central black hole's activity is intensifying. As the active black hole continues to rev up, the rate of star formation will, in turn, be tamped down in the galaxy. ...

In order to measure the density of the Universe, it is necessary to sample a region that is larger than the scale on which the Universe becomes approximately homogeneous. ... When applied to clusters of galaxies we find a mass to luminosity ratio that implies a density of the Universe that is about 0.3 times the critical density. ... Thus the mass-to-muinosity ratio appears to vary with the size of the region measured, from 3 in the solar neighborhood to 30 in galaxies to 300 in clusters of galaxies. ...
