A few reasons I've posted this. 1) It's by a couple of Hong Kong
researchers(!); 2) life on earth could have been brought here
from other stars; and 3) complex organic compounds can form in
space even when no life is present. Science buggering up the
bible again. Tsk. Mixed aromatic–aliphatic organic nanoparticles
as carriers of unidentified infrared emission features Sun Kwok
& Yong Zhang , (2011) doi:10.1038/nature10542 Unidentified
infrared emission bands at wavelengths of 3–20 micrometres are
widely observed in a range of environments in our Galaxy and in
others1. Some features have been identified as the stretching
and bending modes of aromatic compounds2, 3, and are commonly
attributed to polycyclic aromatic hydrocarbon molecules4, 5. The
central argument supporting this attribution is that single-
photon excitation of the molecule can account for the
unidentified infrared emission features observed in ‘cirrus’
clouds in the diffuse interstellar medium6. Of the more than 160
molecules identified in the c
