Forming the ion that made the universe

The trihydrogen cation, H3+, plays a major role in interstellar chemistry where it facilitates the formation of water and organic molecules. Researchers have discovered how the cation forms when organic molecules (particularly alcohols) are excited by an intense laser pulse (artist rendition). Knowing how the cation forms takes us closer …
