Astrochemistry: January 2018


Polycyclic aromatic hydrocarbons and polycyclic aromatic nitrogen heterocycles are thought to be widespread throughout the Universe, because these classes of molecules are probably responsible for the unidentified infrared bands, a set of emission features seen in numerous Galactic and extragalactic sources.

Scientists studying a cold molecular cloud of the Taurus region with radio telescopes have detected the presence of a particular organic molecule called benzonitrile.

Astronomers had a mystery on their hands. No matter where they looked, from inside the Milky Way to distant galaxies, they observed a puzzling glow of infrared light.
