Giant string of organic molecules on Mars may be one of the best signs of life yet
A new NASA analysis concludes that it is "reasonable to hypothesize" that living things could have formed the odd organic molecules discovered on Mars.
Organic molecules discovered within a stone on Mars cannot be fully explained by nonbiological processes, and it's "reasonable to hypothesize" that living things could have formed these odd organic molecules, a NASA-led team reports in a new study. However, this doesn't mean scientists have found definitive proof of life on Mars, they cautioned.
