What significant benefit does the Moon's far side offer for setting up specific types of astronomical instruments?
Its relative isolation from Earth's radio noise
The far side of the Moon presents a unique and highly attractive environment for radio astronomy due to its shielding from terrestrial interference. Because the entire mass of the Moon lies between the far side and Earth, it is effectively isolated from the vast majority of radio frequency interference (RFI) generated by human technology on our planet—what is often termed radio noise. This exceptionally quiet radio background makes the far side an optimal location for constructing radio telescopes designed to detect extremely faint signals originating from the very early universe, which would otherwise be drowned out by Earth-based broadcasts.
