... 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 . ...

... The ancient chronical said about the colour rings around the Sun and the Moon, about three suns in the sky, light columns, bright lightning, different "comets" rushing to the Earth, moving among the stars or round the Earth with the sky. All these occurrences may be divided into three categories: one that occur in the near or far space, processes going on in the Earth atmosphere under the influence of cosmic factors and at last the occurrences connected with the Earth atmosphere. ...

CN And CWA_CB According to lc from Jassur & Khodadadi [352] it is a CBV system because of asymmetry (primary maximum is greater than secondary) and large dA, but according to lc solution it is CWA overcontact system with components in poor termal contact. ... According to Coughlin et al. [354] is a marginal contact system with both components almost fill their critical lobes, light curve asymmetric, so authors use hot spot on the primary to solve light curves. ... So It may be the CW system. ...
