flag ESA launches Proba-3 satellites to study the Sun's corona by creating artificial eclipses.

flag The European Space Agency launched Proba-3, a pair of satellites designed to create artificial solar eclipses to study the Sun's corona. flag This mission is the first to use a two-spacecraft setup, allowing for more extended observation periods compared to natural eclipses, which last only a few minutes. flag The satellites, positioned about 500 feet apart, will cast a shadow on one another to reveal the corona, aiming to answer questions about its extreme temperatures. flag Initial results are expected around four months after the satellites begin operating in sync in early 2025.
