Organic Matter in Space - an Overview

TL;DR

This paper reviews the widespread presence of organic compounds across various space environments, highlighting recent observational and laboratory findings, and discussing their implications for understanding cosmic organic chemistry.

Contribution

It provides a comprehensive overview of observational evidence for space organics and emphasizes the role of laboratory astrophysics in studying their nature and evolution.

Findings

Organic compounds are found in diverse space regions.

The Stardust mission enabled detailed study of cometary organics.

Laboratory astrophysics is crucial for interpreting observational data.

Abstract

Organic compounds are ubiquitous in space: they are found in diffuse clouds, in the envelopes of evolved stars, in dense star-forming regions, in protoplanetary disks, in comets, on the surfaces of minor planets, and in meteorites and interplanetary dust particles. This brief overview summarizes the observational evidence for the types of organics found in these regions, with emphasis on recent developments. The Stardust sample-return mission provides the first opportunity to study primitive cometary material with sophisticated equipment on Earth. Similarities and differences between the types of compounds in different regions are discussed in the context of the processes that can modify them. The importance of laboratory astrophysics is emphasized.
