An international team of astronomers, led by Imperial College London, used a new way of combining data from the two European Space Agency satellites, Planck and Herschel, to identify more distant galaxy clusters than has previously been possible.

«The more distant the galaxy, the further back one is looking, so by measuring their distances we can piece together a timeline of how vigorously the Universe was making new stars at different stages of its 13.7 billion year life,» said Joaquin Vieira (California Institute of Technology, USA), lead author of the paper in the journal Nature.
