Sample images[edit]

In addition to the images of the telescopes themselves, I'd like to see some examples of the output of radio telescopes. For example, a few of the more significant very early images, and some spectacular ones from today. Cheers - Gobeirne (talk)

Why are Radio Telescopes important? Is it that they are able to talk to the space craft due to the waves it gives out?' —Preceding unsigned comment added by (talk) 02:31, 2 October 2009 (UTC)


There seems to be some confusion as to who "invented" the radio telescope - Karl Guthe Jansky or Grote Reber. I assume it arises from the fact that radio astronomy itself was never invented, it was discovered (serendipitously). Karl Jansky's antenna was directional and he used it to map the location of the strongest radio source (the center of the milky way). When he did that he was using it as a radio telescope. Unusual Telescopes by Peter L. Manly, page 76 has a good description of Jansky's first antenna and its usage as a telescope. Grote Reber would not be the "inventor" of the "dish" radio telescope either since the parabolic reflector antennas had been around since 1888 and Jansky proposed one for radio astronomy in 1935[1]. Reber was the first to build an antenna and receiver for the purpose of astronomy and the first to use a parabolic reflecting antenna for astronomy.[2].

Seeming contradiction about the largest radio telescope in Europe[edit]

The article states that the largest single radio telescope in the world is near Nizhnij Arkhyz in Russia, while the largest single radio telescope in Europe is another telescope near Effelsberg Germany. I don't have detailed maps of the mountains, but it looks like Nizhnij Arkhyz is on the north side of the Caucasus mountains, and therefore in Europe. (talk) 21:54, 14 October 2011 (UTC)

Cool, can you add the reference and information to the page?AcuteAccusation (talk) 21:56, 14 October 2011 (UTC)
Well, I just looked at a map. I don't want to get into OR. (talk) 23:25, 14 October 2011 (UTC)
