... 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 . ...

... We guess it's almost impossible to create the site nowadays where all space relative philatelic materials (postage stamps, stationary, postal marks etc.) would be registered and presented. ... We tried to make such a step in April 2005, placing at the site first images of postage stamps with portraits of astronauts (cosmonauts, spacionauts, taikonauts:). ... All illustrative material (or simply speaking, all scans of stamps) are grouped in four sections: Countries , Years , Astronauts and Flights . ...
