SETI Live: Organic Matter Found at Bennu

Amino Acids on Bennu!
Building Blocks for Life Detected in Asteroid Bennu Samples

The OSIRIS-REx (Origins, Spectral Interpretation, Resource Identification and Security–Regolith Explorer) mission has been a resounding success so far, from taking a sample of asteroid Bennu to returning that sample to Earth. Now, the first in-depth analysis of the space rocks is complete, and the results have been published in Nature and Nature Astronomy. One of the most intriguing results shows that 14 of the 20 amino acids that life on Earth uses to form proteins have been found in the sample. This result supports the hypothesis that objects that formed farther from the Sun provided precursor ingredients for life.

Join communications specialist Beth Johnson and senior sample scientist Danny Glavin from NASA's Goddard Space Flight Center for a discussion of these important results and their implications for the development of life.
