Giant radiotelescope in Aresibo. The biggest radio-telescope (300-metres) with the parabolic aerial was created in Arisibo on the Puerto Rico. ... In the height of 150 m above the giant mirror the 600-tones platform is fixed by the steel ropes. People can rise there by the haning bridge or a cable way. ... The computer controlled cabin with the radiation sourses and receives moves on the reels along the platform that is how radio-telescope is set on the investigated sourse. ...
... The main design features of the mirror system of the RT-32 are as follows [1]: . The carcass of the primary mirror is formed as a three-dimensional, welded steel tubular rod system that is highly statically indeterminate and therefore very durable. ... The supporting and driving maschinery of the antenna is T-shaped, so it has a very massive vertical stanchion (its length is 15m and diameter 2.3 m). ...

... 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 . ...
