If radiowaves are reflected from objects (i.e planets) and they can penetrate a bit in the surface, we could image the subsurface right?
If radiowaves are reflected from objects (i.e planets) and they can penetrate a bit in the surface, we could image the subsurface isn't it?
Can we observe planets surfaces and subsurfaces using radio/micro/IR waves passively? Since few gamma and cosmic rays can pass through our atmosphere, can we image Earth with them and using their penetration image its subsurface? If we use ground penetrating radar frequencies with radiotelescopes could we see what’s beyond the surface of planets? Can we use ground penetrating radar frequencies with ground based telescopes into solar system planets to see their subsurfaces? Can we see planets with radio telescopes? How far away from a planet could we theoretically see its surface? What type of electromagnetic radiation can we use to see small things through a 1 or 2mm layer of aluminiuin an earth like planet from here? What would happen if we cover the sun and no light reaches the earth? If I managed to survive a trip to Neptune's liquid mantle, and there was enough light to see, would it look like a vast ocean under an extremely dense cloud cover? Would there be an actual surface that a craft could float on? Has any optical or radio telescope been able to capture images of the surface or atmosphere of an extra-solar planet? How do radio waves work in space? How do we observe non-radio-emiting planets (earth, venus, mars, asteroids…etc) with radiotelescopes? Here's a serious question? If we cover the entire moon surface in mirrors100% would we then have 2 suns? Would we be able to use it for extra solar pw Why do planets moving away from us increase their wavelengths? Could sound waves leave traces in any surface or medium? Could we use a 13 cm radio wavelength to see a 1-0.5 mm object (with little resolution)? Could this be improved to see it better? How or why do radio waves reflect the ionosphere?  How do we observe planets with radio telescopes? How can we image subterranean very small and big objects inside other planets? And know their composition shape and atomic structure? Can radio waves and microwaves penetrate soil/rock/walls/metal? Why does the ionosphere reflect radio waves? Can extremely low frequency radiowaves pass through interplanetary, interstellaer, intergalectic, and farther space? How could science determine if there was a type of light outside of the spectrum visible to us or our current technology? What would it look like through a telescope if all the planets aligned? How are different atmospheres affected by cosmic rays? How does scattering of light take place in earth’s atmosphere? How are cosmic rays affected by different atmospheres? Can there be potentially habitable worlds near the core of the galaxy or is the light and radiation too strong? Could visible lights or photons have a shadow? Why the electrons and nucleons are not visible? Does it related to wavelength of the light? And if Yes How?
