How do we observe non-radio-emiting planets (earth, venus, mars, asteroids…etc) with radiotelescopes?
Interesting. How are these reflected waves different from emitted waves?
Reflected waves have a different structure than emitted waves because they bounce off the surface of the planet and come back to the telescope. This interaction with the planet's surface gives us information about its composition, topography, and other physical properties.
