Carbon is the most essential of elements in forming organic molecules; indeed, life on Earth has been referred to as "carbon based" because of the prevalence of carbon in forming essential compounds for organisms. Carbon is so prevalent in organic compounds because of its ability to form up to...

Studies of meteorites and comets suggest that organic molecules are widespread among both asteroids and comets. ecause each body in the solar system was repeatedly struck by asteroids and comets during the period known as the heavy bombardment (about 4 billion years ago), each body should have ...

Earth' s organic molecules likely came from some combination of three sources: chemical reactions in the atmosphere, chemical reactions near deep-sea vents in the oceans, and molecules carried to Earth by asteroids and comets. The first two sources can occur only on worlds with atmospheres or ...
