    What is radio astronomy?

    2011-09-15T10:32:00Z

    Astronomers use radio telescopes to explore the universe by detecting electromagnetic radiation emitted by objects in space.Radio wave receptors, or antennas, detect the relatively long wavelength (low frequency) radio waves that penetrate the Earth’s atmosphere. These radio signals have frequencies between about 30 MHz and 40 GHz, which is equivalent ...
