Biggest ever cosmos simulation
Astronomers have used supercomputers to re-create how the Universe evolved into the shape it is today.
The simulation by an international team is the biggest ever attempted and shows how structures in the Universe changed and grew over billions of years.
The Millennium Run, as it is dubbed, could help explain observations made by astronomers and shed more light on the Universe's elusive dark energy field.
Details of the study appear in the latest issue of Nature magazine.
