. Images of the position of GRB080319B before the burst (left) and at the moment of maximal optical brightness (right). The transient position is marked with an arrow. Peak optical brightness made the burst visible by a naked human eye (5.3 stellar magnitude). To view high temporal resolution video of the transient seen by TORTORA camera, click here (avi).

... About half an hour after the BAT trigger, the first images were obtained with the SAO RAS Zeiss-1000 telescope in four BVRI filters (see Fig.1). ... The spectrum of the optical transient was obtained with the SAO RAS 6-m BTA telescope 1.54 hours after the burst, using the SCORPIO instrument in the spectroscopic mode (Fig.2). ... The spectrum of the optical transient GRB090726 with identified lines, obtained with the BTA 1.54 hours after the burst. ...
... A new bright LBV (Luminous Blue Variable) star was detected in M33 galaxy. LBV stars are the most massive stars in the final stages of evolution before exploding in of supernovae. ... The new LBV star (Fig.1) is the seventh in M33. ... It is one of the brightest LBV stars of the M33 galaxy. ... The brightest object is the core of the galaxy, - a compact star cluster comprising a supermassive black hole. The new LBV star N93351 is located down and to the left from the core. ...
... Massive stars, having 10-150 masses of the Sun, with metallicities Z tens to hundreds times less than that of the Sun (Zo), are the main regulators of the galaxy formation and evolution processes in the early Universe. ... In this galaxy, using the 6 m BTA telescope, a new massive blue variable star with high luminosity (>=10 5 Sun's luminocities in visible light) was found. As far as its properties are concerned, this star falls into an LBV (Luminous Blue Variable) class of stars. ...
... A radio galaxy is a galaxy that emits an unusually big amount of energy at radio wavelengths. ... Inside of each galaxy with an active nucleus (radio galaxies are among them) there must be a system of a "central machine" responsible for the colossal amount of the emitted energy from radio to gamma ranges. ... Sometimes a radio source in an active galaxy may flare again if the needed conditions appear (a new portion of matter would fall into the furnace of the "central machine"). ...
