> “We are analyzing OSIRIS-REx samples for the chirality (handedness) of individual amino acids, and in the future, samples from Mars will also be tested in laboratories for evidence of life including ribozymes and proteins,” said Dworkin.

I clicked the hyperlink for OSIRIS-REx samples, and it didn’t contain any information about what kinds of materials were found, but this statement suggests amino acids were collected from OSIRIS-REx—did I miss this news? Were there proteins found on an asteroid?

Indeed I did miss that, what an incredible find, I can’t believe this never broke through into my routine news feeds!

How suggestive is this of life elsewhere in the universe?

		On it's own, probably not that much. We know that amino acids can form in interstellar space and have in fact observed clouds of them in star-forming regions[1]. Finding them on a non-planetary object in our own solar system is certainly very cool but we already knew they existed in this neck of the woods. ;-) 1: https://www.space.com/amino-acid-tryptophan-perseus-molecula...
