Radio
Further information: Radio astronomy and Very Long Baseline InterferometryAs the atmosphere is transparent for radio waves, radio telescopes in space are of most use for Very Long Baseline Interferometry; doing simultaneous observations of a source with both a satellite and a ground-based telescope and by correlating their signals to simulate a radio telescope the size of the separation between the two telescopes. Observations can be of supernova remnants, masers, gravitational lenses, starburst galaxies, and many other things.

Famous quotes containing the word radio:
“A liberal is a socialist with a wife and two children.”
—Anonymous. BBC Radio 4 (April 8, 1990)
“from above, thin squeaks of radio static,
The captured fume of space foams in our ears—”
—Hart Crane (1899–1932)
“... the ... radio station played a Chopin polonaise. On all the following days news bulletins were prefaced by Chopin—preludes, etudes, waltzes, mazurkas. The war became for me a victory, known in advance, Chopin over Hitler.”
—Margaret Anderson (1886–1973)
