Scientists have identified the source of mysterious flashes of cosmic radio waves known as fast radio bursts: a surprisingly small galaxy more than 3 billion light - years away. (sciencemag.org)
Radio telescopes must be placed where they can collect the most cosmic radio waves without any radio interference from man or nature. (public.nrao.edu)
In the 1950s, Reber sought a field that seemed neglected by most other researchers and turned his attention to cosmic radio waves at very low frequencies (1 - 2 MHz, or wavelength 150 - 300 meters). (greenbankobservatory.org)
