Scientists have developed a new way of measuring precise distances to galaxies tens of millions of light years away, using the W. M. Keck Observatory near the summit of Mauna Kea in Hawaii. The method is similar to what land surveyors use on Earth, by measuring the physical and angular, or ‘apparent’, size of a standard ruler in the galaxy, to calibrate the distance from this information.
