ESA’s Proba-3 mission has achieved a world first. It created an artificial eclipse in space. Not just once, but over 50 times. In this video, we’ll discover how these two tiny probes are revolutionising our ability to study the Sun’s inner corona, and helping to answer the biggest unsolved mysteries about our star.
