... 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 . ...

... Bad Astronomy . ... On Thursday, February 15th 2001 (and replayed on March 19), the Fox TV network aired a program called ``Conspiracy Theory: Did We Land on the Moon?'', hosted by X-Files actor Mitch Pileggi. ... Dust around the lander . ... However, it appeals to our common sense: when the sky is black here on Earth, we see stars. ... Bad: The program claims that when the top half of the lander took off from the Moon to bring the astronauts back into orbit, there was no flame from the rocket. ...

... Multifrequency study of radio sources with the Virual Obsevatory tools . ... We reliably identified 76 % of radio sources of the RCR catalogue. ... According to available photometric and spectral data for about a half of reliable identified sources we defined types of the host galaxies, and 45% of radiosources are quasars, 16 % are galaxies of late types, 22 % are galaxies of early types, 19 % are galaxies of early types with a high activity in radio range. ...

... Seminar archive . ... The structure of the X-ray sources in the hard spectral state of accreting black-hole binaries has been a subject of intense debate. The paradigm dominant for many years postulated that the accretion disc in the hard state is truncated at some radius >> the innermost stable orbit (ISCO) whereas the disc reaches the ISCO in the soft state. ... On the other hand, there have been numerous claims in recent years that the disc extends to the ISCO in the hard state. ...

The results of a search for ultrarapid variability of galactic water maser sources at the wavelength 1.35 cm on a timescale of several minutes to 1 h are reported. A special observational technique was developed. ... Among those, several sources that have shown such variability were found. ... Clear evidence for such a variability type was found in at least two sources: W49N and W33B. Variability of this kind displays itself only in certain states of the water masers. ...
