radio telescopes
Cosmic signal catchers
Radio telescopes are instruments that detect radio waves from space rather than visible light.
They typically feature large dish antennas that collect faint signals from distant cosmic sources—pulsars, quasars, galaxies, and remnant radiation from the Big Bang.
Arrays of radio telescopes can work together to achieve resolution no single dish could match: The Very Large Array spans miles of New Mexico desert.
