A team of scientists at the Anglo-Austrian Observatory have discovered circular polarization in light from the Orion constellation which may explain homochirality in organic molecules. Chirality, which defines preferences of organisms to build either right-handed sugars or left-handed amino acids, has long baffled scientists.
