... 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 . ...

VIEW OUT OF THE WINDOW FROM ARIZONE, USA . ... Our whole class was excited to share with you what we see when we look out our window here, in Chandler, Arizona. Our classroom has no windows, so we decided to go outside on February 2, 1998, and describe to you what we see. You look out across the desert and you see endless roads and it sees almost as if you are in a dream. It's cold; about 65 degrees F (cold for Chandler, anyway) and there has been a touch of fog this morning. ...

... We address a question if globular clusters (GC) in a protogalaxy could for some time evolve chemically as isolated systems, enriching themselves with heavy elements produced in first supernova events that follow initial star formation. We determine both the critical mass of a protoglobular cluster that is needed to retain the ejecta of the very first supernova, and the critical energy (i.e., number of supernovae) that is needed to expel the residual gas from a cluster of a given mass. ...
