NASA scientists want to solve a mystery: Why did life "turn left?"

NASA 's OSIRIS-Rex mission found no favoritism for left-handed amino acids on asteroid Bennu .
Scientists used samples from asteroid to study amino acids used to build proteins.
Many amino acids come in two mirror-image forms, like a left and right hand, but if you stacked them, the thumbs would be hitchhiking opposite ways.
Bennu 's mineral fragments could be older than the 4.6 billion-year-old solar system.
Researchers have made mirror versions of biological proteins with right-handed amino acids in a lab.
They function similarly, but they're much harder to destroy.
An even mix of both types in an extraterrestrial sample might suggest molecules were made chemically without the involvement of living things.
An excess of one type could be a clue for alien life.
