- 17 June 2016
Propylene oxide is detected in the gas phase in a cold, extended molecular shell around the embedded, massive protostellar clusters in the Sagittarius B2 star-forming region, representative of the earliest stage of solar system evolution in which a chiral molecule has been found.
A Rigorous Attempt to Verify Interstellar Glycine
In 2003, Kuan and coworkers reported the detection of interstellar glycine (NH2CH2COOH) based on observations of 27 lines in 19 different spectral bands in one or more of the sources Sgr B2(N-LMH),…
