Eclipsing binary star system,computer illustration. As the two stars orbit each other they pass in front of one another and their combined brightness,seen from a distance,decreases. By studying how the light changes,and other properties of the system,astronomers can measure the distances to eclipsing binaries very accurately. A long series of observations of very rare cool eclipsing binaries has now led to the most accurate determination so far of the distance to the Large Magellanic Cloud,a neighbouring galaxy to the Milky Way,a crucial step in the determination of distances across the Universe | |
