For the last few years, scientists have been studying a dust cloud near the centre of our Milky Way galaxy. The dust cloud, Sagittarius B2, has the aroma of rum and tastes like raspberries. This gas cloud consists largely of ethyl formate, which gives raspberries their taste, and rum its distinctive smell. This large cloud is said to contain billions of liters of the stuff. However, it is undrinkable because of toxic particles such as cyanide.
