radiotelescope
Cosmic signal receiver
A radiotelescope is an instrument that detects radio waves from space rather than visible light.
Unlike optical telescopes, radiotelescopes use large dish antennas or arrays of antennas to collect faint signals from distant stars, galaxies, and other cosmic sources.
They can observe through clouds and operate day or night.
Also spelled as two words: radio telescope.
