Proceedings of the 170th Symposium of the International Astronomical Union, held in Tuscon Arizona , May 29 - June 5, 1995
Interstellar carbon monoxide (CO) was first detected in 1970 with the 36 foot diameter telescope of the National Radio Astronomy Observatory on Kitt Peak in Southern Arizona. Wilson, Jefferts, and Penzias of Bell Labs reported, "we have found intense 2.6 mm line radiation 2 from nine Galactic sources which we attribute to carbon monoxide". Soon afterwards, several other basic molecules were also observed in space. Symposium 170 was organised to commemorate those discoveries. The Symposium reviewed the accomplishments of a quarter century of research on interstellar molecular gas, surveyed the current state of millimetre-wave spectroscopy, and gave a glimpse of what the next 25 years might hold. Studies of interstellar CO have revolutionised our understanding of the phases and dynamics of the interstellar medium, the initial and final stages of stellar evolution, the chemistry of dense and diffuse interstellar matter and of the solar system, the structure of the Milky Way galaxy, and the content and structure of other galaxies, some very distant.
Very good condition with minimal evidence of use.
