Story summary
- The European Space Agency's Proba-3 mission released its first scientific results, reporting solar wind speeds in the Sun's inner corona of 250–500 km/s.
- These speeds are faster than prior models predicted.
- Proba-3 consists of two satellites that create artificial solar eclipses, enabling unprecedented observations of the corona.
- The findings raise questions about solar wind acceleration and coronal heating.
- Further analysis of the collected data is ongoing.
