Solar Orbiter's discovery of these jets, called "picoflares," could solve the mystery of how the sun keeps blasting Earth with charged particles.
The ESA/NASA Solar Orbiter spacecraft has discovered a multitude of tiny jets of material escaping from the Sun’s outer atmosphere. Each jet lasts between 20 and 100 seconds, and expels plasma at around 100 km/s (60 miles/s) or 360,000 km/h (220,000 mph). These jets could be the long-sought-after so
The Solar Orbiter has spotted tiny short-lived "picojets" for the first time. In just one minute, these tiny jets emit enough energy to power 10,000 households for a year.
The probe has discovered small, brief energy jets known as "picoflare jets" escaping the sun's outer atmosphere, or corona. Astronomers suspect that these plasma jets could be the source of the solar wind.
Researchers say the coronal hole could send solar winds at speeds of up to 2.9 million kilometres per hour toward Earth by the end of the week.
