The homogeneity found among both is especially confounding to scientists because the left and right-handed versions of all ...

Scientists have long wondered why life exclusively uses left-handed amino acids, and a groundbreaking NASA study has just made this puzzle even more intriguing.

Scientists have detected amino acids and complex mineral compounds in NASA's asteroid Bennu rocks, some never seen before in space rocks.

Scientists are particularly curious about how a different set of amino acid building blocks would result in different characteristics in the life it creates.

A NASA experiment suggests -- if these oceans support life -- signatures of that life in the form of organic molecules (like amino acids and nucleic acids) could survive just under the surface ice ...

In samples NASA brought back from the asteroid Bennu, scientists have discovered of organic compounds, including key building blocks of life like amino acids.

Samples of asteroid Bennu contain molecules that suggest the "conditions necessary for life" were widespread across the early solar system, according to NASA.

A NASA spacecraft has returned asteroid samples that hold not only the pristine building blocks for life but also the salty remains of an ancient water world.

Molecules friendly to life have been found in samples of the asteroid Bennu, which NASA collected with a robotic probe five years ago.

NASA and other institutions studying the Bennu asteroid sample announced the discovery of molecules and minerals that are key ingredients for life to exist.

Rock and dust samples from the Bennu asteroid contain molecules that are the "key to life" on Earth, NASA officials announced on Wednesday.
