Exotic Molecules: Chemist Confirms Existence of Key Space Molecules Using Lasers

Chemist Kim Steenbakkers confirmed the existence of space molecules using lasers, defending her Ph.D. research at Radboud University on June 3. She studied molecules on Earth under space-like conditions to identify their unique fingerprints. Steenbakkers used the HFML-FELIX lab to cool molecules to -270°C and reduce pressure, mimicking space. She fired an infrared laser at charged molecules like CH and HCH, obtaining their fingerprints. This method helped identify CH in the Orion Nebula using the James Webb Space Telescope. Understanding space chemistry can reveal insights into star and planet formation, and the origins of life.
