Analysis of soil samples from asteroid Bennu, delivered to Earth in September 2023, has revealed key components essential for the emergence of life. Scientists detected 14 of the 20 natural amino acids involved in protein formation, along with five nitrogenous bases that form the foundation of DNA and RNA. Additionally, ammonia and formaldehyde—compounds that contribute to the formation of complex organic molecules—were found in the samples.
Another study describes conditions favorable for the synthesis of amino acids and proteins. Evidence of an ancient liquid environment was detected in the samples, suggesting it could have facilitated chemical processes leading to the emergence of life. Among the discoveries were 11 minerals, including calcite, halite, and sylvite—crystals formed by the evaporation of saltwater. These findings support the idea that Bennu may have undergone processes similar to those that laid the groundwork for life on Earth.
