There are 20 amino acids that create the proteins required for life on our planet — and scientists have now found exactly 14 of them on an asteroid millions of miles away. The asteroid in question, ...

All forms of Earth life have specific chemicals in their makeup, such as amino acids and sugars. Scientists have known that ...

Scientists have finally had a close look at the rubble collected by a spacecraft from the asteroid Bennu. Here's what they found inside and what it could tell us about the origin of life on Earth.

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

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

NASA's Osiris-Rex spacecraft returned 122 grams ... tease out the sodium-rich minerals and confirm the presence of amino acids, nitrogen in the form of ammonia and even parts of the genetic ...

The origins of life on our planet remains one of science’s great mysteries. Now, a NASA mission that brought a piece of an ...

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

The scientists also described "exceptionally high abundances of ammonia", which can react with formaldehyde, also found in the samples, to form complex molecules like amino acids, NASA said.
