Quizplus · Accepted Answer

Long-chain carbon-based molecules have been found in meteorites, massive interstellar clouds of gas and dust, and on the surface of Earth. However, they have not been found on the surfaces of planets and moons such as Venus and Jupiter's moon Callisto due to the high temperatures and lack of suitable conditions for their formation and preservation.
