. The great September commet of 1882. This brightest comet was seen by many people. It shole like 60 full Moons and in the daylight was seen with the Sunlight. But the core of this comet was broken into two parts after the approaching with the Sun. The parts of the comet will return in 2650. Back .

... 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 . ...
