- 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.
- These jets could be the long-sought-after source of the solar wind.
- The solar wind consists of charged particles, known as plasma, that continuously escape the Sun.
- It propagates outwards through interplanetary space, colliding with anything in its path.
- When the solar wind collides with Earth’s magnetic field, it produces the aurorae.
