Complex Hydrocarbons Discovered in the Red Rectangle Nebula

In 2004, scientists discovered hydrocarbons like anthracene and pyrene within the amazing structure known as the Red Rectangle nebula. This nebula, 2300 light-years away, features two stars orbiting each other and emitting a vast torus of icy dust and hydrocarbon molecules. These complex molecules are surprisingly common in space, found in meteorites and even supernova shockwaves. Scientists hypothesize that these polycyclic aromatic hydrocarbons (PAHs) were crucial precursors to life on Earth and play a dominant role in the interstellar 'organic chemistry ecology'.
