The European Radio Astronomy club ERAC is Europe 's only group coordinating the work of radio astronomers to jointly use radio waves to study the universe at radio wavelengths. It was founded in by Peter Wright, who had the idea of writing a small newsletter to the then only strong radio astronomy community in Europewhich were up to this date linked only by letters. Today E.

Radio and radar astronomystudy of celestial bodies by examination of the radio-frequency energy they emit or reflect. Radio astronomers can therefore obtain a much clearer picture of stars and galaxies than is possible by means of optical observation. The construction of ever larger antenna systems and radio interferometers see telescope: Radio telescopes and improved radio receivers and data-processing methods have allowed radio astronomers to study fainter radio sources with increased resolution and image quality. In the American physicist Karl Jansky first detected cosmic radio noise from the centre of the Milky Way Galaxy while investigating radio disturbances that interfered with transoceanic telephone service.

Radio astronomy is a subfield of astronomy that studies celestial objects at radio frequencies. The first detection of radio waves from an astronomical object was inwhen Karl Jansky at Bell Telephone Laboratories observed radiation coming from the Milky Way. Subsequent observations have identified a number of different sources of radio emission.

The Hydrogen line HI is transmitted when the 'spin' a quantum variable of an electron changes direction. This is exceedingly unlikely to happen - the probability is that for a single atom is that it will happen once every 10 million years. However, in a cloud of several billion atoms a weak signal is produced and this can be detected on a receiver that is tuned to

The telescope was used to produce the 5C catalogue of radio sources. Observations with larger incremental spacings were used to observe individual radio sources with unprecedented sensitivity, angular resolution, and image quality. These surveys required intensive use of inverse Fourier Transformsand were made possible by development of a new generation of computers such as the Titan.

This is a list of radio telescopes — over one hundred — that are or have been used for radio astronomy. The list includes both single dishes and interferometric arrays. The list is sorted by region, then by name; unnamed telescopes are in reverse size order at the end of the lists.
