Telescope Quote by Carl Sagan
““A radio telescope works more like a light meter than a camera. You point it toward some fairly broad region of the sky, and it records how much energy, in a particular radio frequency, is coming down to Earth.””

In simple terms: Radio telescopes measure energy, not pictures.
Use appropriate tools for measurement.
