Morphology
The meaning of 'radio telescope' is directly compositional: combining 'radio' (related to radio waves/signals) with 'telescope' (a device for observing distant objects) yields an instrument for observing radio emissions from space. This noun–noun compound follows a common and cross-linguistically familiar pattern, so a B1 learner who knows both constituents will readily infer the correct meaning.
Etymology
The compound noun radio telescope comes from joining radio and telescope. Early instruments were big dish antennas that acted like an ear, 'listening' to radio waves from space instead of using light, so radio telescope means 'an instrument that detects radio waves from space'.
