This project aims to provide astronomers of the future with firm diagnostic tools to identify and understand exotic carbon species in the interstellar medium. Life on Earth began after delivery of carbon-based pre-biotic material to the young planet by comets and meteorites. This material came from outside the solar system, but we do not yet know the chemical make-up of the interstellar matter. This is because we do not understand precisely how the interstellar molecules and dust interact with starlight. This project will create and study models of interstellar matter in the laboratory, and will determine the chemical form of carbon in the interstellar medium. This will have lasting impact on astrophysical models, as well as theories of the origin of life.

该项目旨在为未来的天文学家提供可靠的诊断工具，以识别和了解星际介质中的外来碳物种。地球上的生命是在彗星和陨石向年轻行星传送碳基生命前物质后开始的。来自太阳系之外，但我们还不知道星际物质的化学组成，这是因为我们不准确地了解星际分子和尘埃如何与星光相互作用。事情在实验室中，并将确定星际介质中碳的化学形式，这将对天体物理模型以及生命起源理论产生持久影响。
