How recurrent fluorescence helps organic molecules survive extreme interstellar conditions

The James Webb Space Telescope (JWST) has unlocked the depths of interstellar space with unprecedented clarity, offering humanity a high-resolution window into the cosmos. Harnessing this newfound capability, an international team of researchers set out to investigate how polycyclic aromatic hydrocarbons (PAHs)—organic molecules and key players in cosmic chemistry—survive the harsh conditions of space and uncover the mechanism behind their resilience.
