First Proba-3 science: surprisingly speedy solar wind

ESA's Proba-3 Reveals Solar Wind Moves 4x Faster Since July 2025, the European Space Agency's twin Proba-3 satellites have created 57 artificial solar eclipses, collecting 250+ hours of high-resolution corona footage. Recent findings published in The Astrophysical Journal Letters reveal that solar wind structures travel three to four times faster than previously thought, revolutionizing understanding of space weather origins.
