What does the Oort cloud look like?
Oort cloud is basically composed of huge rocks and comet material. It is about a light year away from earth. It is huge by earth’s stadards. It is believed to be the source of all comets that have orbits all through the Solar system and beyond. Halley’s comet for instance is known to visit our neighborhood at known periodic intervals. Now to answer your question: Oort cloud will look same like any other cloud when seen through a extra powerful telescope in ideal conditions. Only it is not composed of water vapor as in clouds in earth’s atmosphere, but of hard rock like particles.
