The discovery is just the latest to come from the asteroid sample, which dates back to the dawn of the solar system.
Amino acids, the building blocks necessary for life, were previously found in samples of 4.6-billion-year-old rocks from an ...
"We found an unexpected chemical complexity, with abundances far higher than predicted by current theoretical models." ...
A pair of new studies suggest that key steps toward life’s chemistry may begin long before planets exist. Experiments simulating interstellar space show that simple amino acids can link into peptides, ...
Amino acids from asteroid Bennu suggest that some of life’s building blocks formed in icy conditions in the early solar system.
