observación de radio
- From radio observations of pulsars, the most accurate determination to date of the interstellar magnetic field has been made.
Examples
-
Recent optical and radio observations have provided dynamical evidence for such massive compact objects in several relatively nearby galaxies by viewing the orbital motion of gas within a few light-years of the galaxy centers (see PHYSICS TODAY, August 1994, page 17, and March 1995, page 9).

In many cases, jets are very small or hidden by cosmic dust—not a problem for the radio observations, which can see through the dust with sub-arcsecond resolution.
Academic text (1995) -
We infer this because we know (from optical and radio observations) that there is a disordered magnetic field (of a few microgauss) throughout the interstellar medium in which the cosmic rays travel.

Morphology
radio + observation
The meaning 'an observation made using radio waves/a radio telescope' is directly derivable from combining 'radio' (relating to radio waves or radio equipment) with 'observation' (the act of watching or recording). This is a straightforward noun–noun technical compound following normal English composition patterns, so a B1 learner who knows both constituents would readily infer the intended meaning.
Etymology
Radio observation comes from the clear image of using a large radio to 'listen' to the sky while making an observation by recording what you hear. That's why it means to study space by 'listening' to radio signals with a radio telescope.
