A vertical solar telescope feeds a white-light image of the Sun into the undergraduate astronomy laboratory. The coelestat mirror system shown here tracks the daily motion of the Sun and directs light downward into the telescope supported from the ceiling of the astronomy lab. ... Conditions in the ionosphere responsible for the strength of the signal are very sensitive to X-ray flux from solar flares and sudden x-ray emitting events outside the solar system, and rapidly alter the received signal. ...

Installed and tested in late November 2000, new world-leading technology has made the Australia Telescope Compact Array (ATCA) the first millimetre-wave interferometer in the Southern Hemisphere. At the heart of the new millimetre receivers are indium phosphide chips, cooled to 20 K (-253њ C), the product of a joint effort between the Australia Telescope National Facility (ATNF) and the CSIRO Division of Telecommunications and Industrial Physics (CTIP). ... bkoribal@atnf.csiro.au ) ...

... 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 . ...
