摘要：

An apparent discrepancy between two independent distance measurements to a faraway glalaxy may lead to a revised value for the age of the Universe. The latest distance estimate is based on the discovery of large variable stars -- known as Cepheids -- in this galaxy. But the blending effects caused by images of Cepheids being mixed with other stars may provide a solution to the distance problem.
