formation of complex organic molecules in dense clouds-Sweet results from laboratory
Large areas of space are filled by molecular clouds that consist of gas and dust grains that are the remnants of dead stars. When these clouds start collapsing, the decreasing temperature and increasing density cause gas particles to start accreting onto dust grain surfaces.

Harold Linnartz bij BNR Nieuwsradio over het bouwen van moleculen in de ruimte
Moleculen zijn de bouwstenen van het leven. Ze ontstaan door chemische reacties die plaatsvinden als atomen met elkaar botsen. In het ijle heelal zijn deze botsingen zeldzaam en de omstandigheden extreem. Toch zijn ook hier complexe moleculen te vinden en gebeuren er dus chemische reacties. Hoogleraar…
