The 2dF QSO Redshift Survey (2QZ) . ... Before jumping into all the finer details of teh survey, a brief non-astronomer's guide to redshift surveys is available. ... The primary scientific aims of the QSO survey are: (1) to obtain the primordial fluctuation power spectrum out to COBE scales, (2) to determine the rate of QSO clustering evolution in the non-linear and linear regimes and hence obtain new limits on the value of and the bias parameter, (3) to apply a powerful geometric method to measure . ...

... New technique measures mass of exoplanets . ... Now, scientists at the Massachusetts Institute of Technology (MIT) have developed a new technique for determining the mass of exoplanets using only their transmission spectra dips in light as a planet passes in front of its star. ... To determine the mass of an exoplanet using transmission spectroscopy, de Wit relied on the effect that a planet s mass has on its atmosphere, as transmission spectra give information on a planet s atmospheric properties. ...
