Space Radio Telescope . The space radio telescope antenna consists of a deployable parabolic reflector (10-m diameter) which is made of 27 carbon fiber petals and central solid portion (3 m in diameter). The radio telescope has focus to diameter ratio F/D=0.43 and overall RMS surface accuracy 0.7 mm. ... A concentric feed arrangement at prime focus will provide the possibility of observing at two frequencies or two circular polarizations simultaneously. ... Observing frequency (MHz) . ...

... 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 . ...
