... DIAGNOSTICS OF IONOSPHERIC IRREGULARITY SPECTRUM USING MEASUREMENTS OF RADIO WAVE ANOMALOUS ATTENUATION UNDER VERTICAL SOUNDING . ... The selected experimental data are characterized by a high average level of attenuation of a signal of vertical sounding (10 dB and above), which cannot be caused by collisional absorption of radio waves (practically absent in a dark time of day) and, hence, being a consequence of scattering on random irregularities. ... ATTENUATION OF A VERTICAL SOUNDING SIGNAL . ...
... I will touch upon the following points: fast evolution of the sizes of quiescent (elliptical) galaxies between z = 2 and z = 1; prolonged star formation histories of dwarf spheroidal galaxies in the Local Group; apparent lack of external sources of cold gas accretion for the nearby spiral galaxies; old stellar ages and magnesium overabundance of the large-scale disks of nearby lenticular galaxies. ... This discovery has challenged the recognized scenarios of elliptical galaxy evolution. ...

... The Sun has come all of one day away from breaking its record for the longest period of inactivity for the last decade - reaching a mid-summer low and falling into yet another state of "hibernation". Yesterday, on the first day of autumn, new sunspots appeared on the surface of the Sun following an absence of almost 50 days. ... The first low lasted 51 days, from 21 July until 11 September last year. ... Now, almost a year later, it seems the Sun has hit a new low almost as "deep" as the first. ...

... 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. ...
