Cosmic-ray telescopes spot planetary rays and also normally consist of an array of different detector types spread out over a big area.

Neutrino detectors, the equivalent of neutrino telescopes, utilized for neutrino astronomy They consist of a large mass of water as well as ice, surrounded by a variety of delicate light detectors referred to as photomultiplier tubes. Greater power X-ray and Gamma-ray telescopes refrain from concentrating completely and also use coded aperture masks: the patterns of the darkness the mask develops can be reconstructed to develop a picture.

In the 20th century, lots of brand-new types of telescopes were developed, consisting of radio telescopes in the 1930s and infrared telescopes in the 1960s. The largest mirroring telescopes presently have objectives larger than 10 m (33 feet), and also work is underway on a number of 30-40m layouts.

Various kinds of telescope, operating in different wavelength bands, give various information concerning the very same object. The 20th century also saw the growth of telescopes that worked in a large range of wavelengths from radio to gamma-rays The very first objective developed radio telescope entered into operation in 1937.

The "onion" dome at the Royal Observatory, Greenwich housing a 28-inch refracting telescope with a staying sector of William Herschel's 120-centimetre (47 in) size reflecting telescope (called the" 40-foot telescope" because of its focal length) in the foreground.
