The European Space Agency's Proba-3 mission is successfully creating artificial solar eclipses, lasting up to five hours, by precisely flying two spacecraft in formation. This innovative technique allows for unprecedented, extended observation of the sun's corona, a region previously difficult to study. Early findings from these artificial eclipses reveal that the slow solar wind is traveling significantly faster than anticipated, with speeds three to four times greater than predicted close to the sun.
