I If radiowaves are reflected from objects (i.e planets)....

AI Thread Summary
Radiowaves can penetrate surfaces to some extent, which raises the question of whether subsurface imaging is possible. However, once radiowaves reflect off a surface, they are no longer available to reflect off subsurface structures. Subsurface imaging of celestial bodies like the moon has been successfully conducted, primarily using satellite technology. Earth-based observations face significant challenges that complicate this process. The discussion was redirected to an existing thread where similar questions have already been addressed.

...and they can penetrate a bit in the surface, we could image the subsurface right? I do not see the problem...
Help please!

If they have already reflected off the surface, they aren't around any more to be reflected by something beneath the surface.
 
Subsurface imaging of the moon has been done rather extensively.
 
Imaging with a satellite would be relatively easy but there must be enormous problems using Earth based observation.
 

Thread 'Does it make sense to build new radio telescopes?'

TL;DR Summary: In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation. In case of failure to detect alien signals, it will further expand the radius of the so-called silence (or rather, radio silence) of the Universe. Is there any sense in this or is blissful ignorance better? In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation.

Thread 'Could gamma-ray bursts have an intragalactic origin?'

Thread 'Could gamma-ray bursts have an intragalactic origin?'

This is indirectly evidenced by a map of the distribution of gamma-ray bursts in the night sky, made in the form of an elongated globe. And also the weakening of gamma radiation by the disk and the center of the Milky Way, which leads to anisotropy in the possibilities of observing gamma-ray bursts. My line of reasoning is as follows: 1. Gamma radiation should be absorbed to some extent by dust and other components of the interstellar medium. As a result, with an extragalactic origin, fewer...
