The first moving images of a black hole could reveal swirls of plasma and collapsing stars, deepening our understanding of the universe.

The extent of job losses needed to address a £30m black hole in its budget is not yet clear, Cardiff University's vice-chancellor has said. A voluntary redundancy scheme at Wales' biggest university closed last month but Prof Wendy Larner said she did not have definite numbers of post closures and did not rule out compulsory job losses.

New research suggests that we may be vastly underestimating the number of black holes that existed in the early universe, which could help answer a big question in cosmology. As detailed in a study published in The Astrophysical Journal Letters,

Stephen Hawking, Roger Penrose, Robert Oppenheimer, Karl Schwarzschild, John Wheeler, Albert Einstein, Leonard Susskind – these renowned scientists all, in one way or another, helped black holes
