Planck telescope's four-year mission comes to an end
Scientists in Wales have been helping to answer the age-old question of how the universe began.
A camera built at Cardiff University for the Planck telescope has been exploring the fringes of our galaxy for the last four years.
It has so far identified 15,000 new objects, among them clusters of galaxies that are some of the largest cosmic structures ever seen.
