The start of 2026 has presented challenges for China’s space program, with two failures reported in its first six launch attempts. However, the year is anticipated to be a transformative
Graphical Abstract — astro-ph.SR Small polycyclic aromatic hydrocarbons and somewhat larger cyano derivatives were detected in the cold dark cloud TMC-1 recently. Their formation from smaller hydrocarbons is not well
