A team of researchers led by the University of Hawaiʻi at Mānoa Department of Chemistry has uncovered a faster way large carbon-based molecules may form in space, helping solve a long-standing mystery about how some of the building blocks of the universe grow.
The study, published in Nature Communications in August 2026 and first-authored by chemistry graduate student Shane Goettl, identifies a new chemical process that could explain the rapid formation of polycyclic aromatic hydrocarbons (PAHs)—large molecules made of carbon and hydrogen that are found throughout the universe, from dying stars to clouds of gas between stars.
Scientists have known these molecules are abundant ...
