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:
“England has the most sordid literary scene I’ve ever seen. They all meet in the same pub. This guy’s writing a foreword for this person. They all have to give radio programs, they have to do all this just in order to scrape by. They’re all scratching each other’s backs.”
—William Burroughs (b. 1914)
“All radio is dead. Which means that these tape recordings I’m making are for the sake of future history. If any.”
—Barré Lyndon (1896–1972)
“... 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)
