"Astronomers searching for the building blocks of life in a giant dust cloud at the heart of the Milky Way have concluded that it tastes vaguely of raspberries. The unanticipated discovery follows years of work by astronomers who trained their 30m radio telescope on the enormous ball of dust and gas in the hope of spotting complex molecules that are vital for life. Finding amino acids in interstellar space is a Holy Grail for astrobiologists, as this would raise the possibility of life emerging on other planets after being seeded with the molecules. In the latest survey, astronomers in Spain sifted through thousands of signals from Sagittarius B2, a vast dust cloud at the centre of our galaxy. While they failed to find evidence for amino acids, they did find a substance called ethyl formate, the chemical responsible for the flavor of raspberries … and the smell of rum."
