In the same way that familiar optical telescopes analyze electromagnetic waves in the visible spectrum (Light), there are other telescopes capable of analyzing other areas of the spectrum.
Thus we can find X-ray, infrared or, like the one we are dealing with today, so-called radio telescopes.
A radio telescope is an apparatus used to capture radio waves, emitted by radio sources, using a huge satellite dish or a set of them.
Although several such radio telescopes exist on Earth, NASA is studying the feasibility of installing one in a crater on the dark side of the Moon (after removing Pink Floid).

The Lunar Crater RadioTelescope (LCRT), which is what the creature is called, can observe the universe at ultra long wavelengths that are reflected in the Earth's ionosphere and which until now have been very little studied.
The idea is to deploy a 1 kilometer diameter wire mesh, using robots, in a 3-5 km diameter lunar crater on the far side of the Moon.
The Moon would act as a shield isolating the telescope from radio interference / noise from terrestrial sources, ionosphere, satellites, etc.
This could lead to great scientific discoveries in the field of cosmology, by looking at the early universe in the 10–50 m wavelength band, which has not been explored by man to date.

Things are still very green and they haven't even chosen the right crater to install the radio telescope, but if they have already thought about it, they will end up building it.
Who knows if in the not too distant future we will be able to listen to Ganymede's top 40 on some extraterrestrial MF station.
