NASA scientists found amino acids, key minerals, and nucleobases for DNA in samples from the OSIRIS-REx asteroid mission. It's a win for alien life.

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 detected all five nucleobases -- building blocks of DNA and RNA -- in samples returned from asteroid Bennu by NASA's OSIRIS-REx mission. Japanese collaborators detected all five ...

The building blocks of DNA have been found in samples returned to Earth from an asteroid, suggesting life rained down from space and could have formed elsewhere. In 2016, Nasa sent its Osiris-Rex ...

Researchers found that the fragments harbored all five nucleobases — the “letters” that comprise DNA and RNA — as ... “NASA’s OSIRIS-REx mission already is rewriting the textbook ...

NASA's OSIRIS-REx mission returned 121.6 grams of sample ... molecules required for building DNA and RNA, supporting the theory that asteroids could have brought the building blocks of life ...

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

Rock and dust samples retrieved by NASA from the asteroid Bennu exhibit some of the chemical building blocks of life, according to research that provides some of the best evidence to date that such ...
