The black hole. ... The black holes are generated in the result of a collapse of giant stars with the mass more than three Sun's masses. ... And moreover the gas near the neutron star or the black hole will get hot and will become a source of high energetic electromagnetic radiation in X-rays and gamma range. ... In the majority of double systems, being the sources of X-rays radiation, the invisible component mass does not exceed the two solar masses, so it is a neutron star. ...

... By undertaking a spectral and photometric investi­ gation of the central part of the bright elliptical galaxy NGC 759, we have found an optical counterpart for the circumnuclear molecular gas ring with the radius of # 3 ## (# 1 kpc) which was earlier reported by Wiklind et al. ... 2 Fig. ... More likely, this ring may be a consequence of a tidal encounter between the elliptical galaxy NGC 759 and a large spiral galaxy which was accompanied by a substantial gas accretion. ...

The ring wall, especially well preserved along the southeast shore of the lake, the steep banks and the great depth, all indicated that at one time there had been a powerful explosion here. ... It is possible that the depth may have been 40 meters before but that the slumping of the banks was helping to decrease the depth. ...

... Module Kvant-2 was launched from Baikonur on November 26, 1989 by the LV Proton-K. It is divided into three air-tight parts with the total volume 59 m3. The total length of the module is 13.7 m; maximum diameter 4.3 m; mass at the launch 19565 kg. Mass of the useful load of the module is 5000 kg, of the fuel- 1100 kg. The area of the solar batteries is 53.2 m2 (6.9 kW). ... It docked to the nose docking port of the core vehicle and by its robot arm redocked to the side port. ...

... Under certain conditions, like those in the nucleus of a QSO, all atoms can be made to emit light at particular wavelengths. ... If that source is approaching the observer, the wave is squashed up onto itself making the wavelength shorter. ... This is redshift. ... You can see how the section of the QSO spectrum which we observe changes with redshift. ... We then see how far we had to slide the observed spectrum along the scale to make it match and that is the objects redshift. ... The 2QZ team . ...
