Benz[e]acephenanthrylene is an organic compound with the chemical formula C20H12. It is a polycyclic aromatic hydrocarbon (PAH) made of four benzene rings around a 5-membered ring.
On February 22, 2014, NASA announced a greatly upgraded database[3][4] for detecting and monitoring polycyclic aromatic hydrocarbons (PAHs), including benz[e]acephenanthrylene (as benzo[b]fluoranthene, a synonym), in the universe. According to NASA scientists, over 20% of the carbon in the universe may be associated with PAHs, possible starting materials for the formation of life.[3] PAHs seem to have been formed shortly after the Big Bang, are abundant in the universe,[5][6][7] and are associated with new stars and exoplanets.[3]
