..."A new find in deep space may explain one of the biggest mysteries here on Earth. Researchers have spotted the first evidence of a chiral molecule—a molecule with two mirror image “twins”—in interstellar space.

And though it isn’t directly involved in biochemical reactions, it may shed light on how the chiral molecules that ultimately led to life on Earth formed in the first place."...
