Modern Inventions: The 200-Inch Telescope


We have produced a Style Guide to help editors follow a standard format when editing a listing. If you are unsure how best to edit this programme please take a moment to read it.
W.H. Steavenson, F.R.A.S.
The 200-inch telescope that is being built in California will be by far the most powerful in the world.
Dr. Steavenson, who is known to listeners for his monthly talks on the stars in the series 'Science Review', will describe the problems of constructing a telescope of this size— how, for example, it took the best part of a year to cool the glass disc for the mirror, and how an even longer time has been spent in grinding and polishing its surface. He will also tell listeners something of what astronomers are hoping to discover when the telescope is finished.


Speaker: W.H. Steavenson

Modern Inventions: The 200-Inch Telescope

Regional Programme London, 27 March 1939 18.40

About this project

This site contains the BBC listings information which the BBC printed in Radio Times between 1923 and 2009. You can search the site for BBC programmes, people, dates and Radio Times editions.

We hope it helps you find information about that long forgotten BBC programme, research a particular person or browse your own involvement with the BBC.

Through the listings, you will also be able to use the Genome search function to find thousands of radio and TV programmes that are already available to view or listen to on the BBC website.

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.
