Star-and Planet-Forming Regions May Hold Key to Life's Chirality
Moffett Field CA (SPX) Apr 26, 2013
Life on Earth is made of left-handed amino acids (L-amino acids). The question of why organisms on Earth consist of L-amino acids instead of D-amino acids or consist of D-sugar instead of L-sugar is still an unresolved riddle. Recent research into star and planet formation throws new light on this question. A research team with Jungmi Kwon (GUAS/NAOJ) has performed deep imaging linear and circular polarimetry of the 'Cat's Paw Nebula' (NGC 6334), located in the constellation Scorpius, and detected ... read more
