Proba-3 vede il vento solare correre più del previsto

I primi dati di Proba-3 mostrano getti di vento solare a 250-500 km/s nella corona interna, molto più veloci del previsto.

First Proba-3 science: surprisingly speedy solar wind

Since July 2025, the European Space Agency’s pair of Proba-3 satellites has already created 57 artificial solar eclipses. So far, the mission has collected more than 250 hours of high-resolution videos of the Sun’s atmosphere, called the corona. That’s the same amount of observing time as about 5000 total solar eclipse campaigns carried out on Earth.  But the science is even more exciting. For the first time we can carefully track how material from the Sun moves through the inner corona, where space weather is born. The first results, recently published in The Astrophysical Journal Letters, show that solar wind structures in the inner corona can travel three to four times faster than scientists thought.
