Synopsis
How large is the universe? Astronomers measure the distances of very remote objects by using spectroscopes, but today there are some doubts as to whether the measurements are reliable. Two star-systems in the constellation of the Fishes appear to give very confusing results. Patrick Moore talks to Iain Nicolson about these new results and what they may mean.
