Comet Lovejoy Left Lots Of Alcohol In Space
An international team of scientists studied Comet Lovejoy as it passed close to the sun in early 2015, using a radio telescope in Spain to identify the molecules that the comet was giving off. Among them, they found ethyl alcohol and glycolaldehyde, a simple sugar. Their findings represented the first time these molecules have ever been observed in a comet, and could lend credence to the idea that comets brought the building blocks of life to Earth.
