The bodies of the planetary system, including the interplanetary matter, can be investigated nowadays by direct measurements at the locality of the object by using space probes. Our knowledge of the structure of the universe beyond the limits of the solar system, on the other hand, depends exclusively on the radiation fields of the cosmic objects (including particle streams and possibly gravitational waves) observable at the location of a terrestrial or “extra-terrestrial” observer.
