The building blocks for life, including salts, organic matter and amino acids have been found in samples returned to Earth from outer space.

The Bennu samples contain 14 of the 20 amino acids that are essential for life on Earth to build proteins. Also found were all five of the basic building block for life — Guanine, Cytosine, Adenine, ...

Scientists from NASA’s OSIRIS-REx asteroid sample return mission recently delivered remarkable findings about asteroid 101955 Bennu after the ... in RNA and DNA, including instructions on ...

Samples from NASA’s OSIRIS-REx mission show the asteroid Bennu had organic molecules and minerals and possibly salty water and other life ingredients.

A mosaic image of asteroid Bennu, composed of 12 PolyCam images collected by the ... Those chemicals are key to building both DNA and RNA, the compounds that give rise to all living things on Earth.

In addition to the 14 biological amino acids, the samples from Bennu also contained 19 more non-biological amino acids, as well as the five nucleobases that make up RNA and DNA. The team also ...
