A team led by researchers at MIT in the United States has discovered large molecules containing carbon in a distant interstellar cloud of gas and dust.This is exciting for those of us who keep lists of known interstellar molecules in the hope that we might work out how life arose in the Universe. But it's more than just another molecule for the collection. The result, reported today in the journal Science, shows that complex organic molecules (with carbon and hydrogen) likely existed in the cold...
