The Distance of the Galaxies by D. W. Dewhirst Ph.D. ,of the Observatories,
University of Cambridge
One of the great advances in astronomy -comparable with those made by Copernicus and Galileo-was the demonstration, in the 1920s, of the vast scale of the universe. For the next quarter of a century astronomers supposed they knew the distance of the galaxies with some accuracy.
Now it seems that these distances have been greatly underestimated. Dr. Dewhirst, who has recently returned from visits to observatories in the U.S.A. and in the Southern hemisphere, discusses our present knowledge of this problem.

There are more than 5 million programme listings in Genome. This is a
historical record of the planned output and the BBC services of any
given time. It should be viewed in this context and with the
understanding that it reflects the attitudes and standards of its time
- not those of today.
Genome is a digitised version of the Radio Times from 1923 to 2009 and
is made available for internal research purposes only. You will need to
obtain the relevant third party permissions for any use, including use in
programmes, online etc.
This internal version of Genome, which includes all the magazine covers,
images and articles as well as the programme listings from the Radio
Times, is different to the version of BBC Genome that is available
externally/to the public. It is only available inside the BBC network.
