Abstract: The last 50,000 years of stellar evolution represents the most active period of synthesis of organic com‐pounds in a stars life. Over 60 gas‐phase molecules, including rings, radicals, and molecular ions have been identified by millimeterwave and infrared spectroscopic observations through their rotational and vibrational transitions. Space infrared spectroscopic observations of emissions from the stretching and bending modes of aliphatic and aromatic compounds have revealed a continuous synthesis of organic material over a period of only a few thousand years under vacuum conditions. These organic gases and solids are ejected into the interstellar medium through stellar winds and spread all over the Galaxy.
