Something that blows me away is scientists have found several complicated molecules necessary for life in interstellar space. The most recent of these is napthalene, a chemical composed of two benzene rings. Isn't that amazing that something that complicated would be formed in interstellar gas clouds? It was found by Susana Iglesias Groth and others in a region of star formation in the constellation Persius. Finding chemicals like this in interstellar space is good circumstantial evidence that life can probably be found in other solar systems.
