Since October 2013 the NASA/ESA Hubble Space Telescope has been observing some of the most massive structures in the Universe -- galaxy clusters. Using the magnification effect caused by their mass, Hubble can look deeper into the Universe than ever before. In this new Hubblecast, Dr J talks about the goals and the achievements of this campaign, called the Frontier Fields programme.
