This photograph shows the Large Magellanic Cloud, a neighbouring galaxy to the Milky Way. ... By studying how their light changes and other properties of these systems, astronomers can measure the distances to eclipsing binaries accurately. A long series of observations of these objects has now led to the most accurate determination so far of the distance to the Large Magellanic Cloud тАФ a crucial step in the determination of distances across the universe. ...
