ESA's Proba 3 is unlocking secrets of the solar wind

This has been the dream of astronomers and solar scientists for ages. A new mission gives solar researchers a powerful new tool in their arsenal: total solar eclipses on demand. Launched in 2024, the European Space Agency’s Proba-3 mission has proven the feasibility of a free-flying space coronagraph. Today, the mission’s first scientific results give us an idea of ​​the origins of space weather. The results were recently published in The Astrophysical Journal Letters.
