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

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, named Bennu, was the focus of a very dreamy NASA mission called OSIRIS-REx that launched in 2016.

Scientists from NASA and other institutions who have been analyzing the Bennu asteroid sample that returned to Earth last September found molecules, including amino acids, which are essential ingredients of life as we know it.
