Coronal holes are areas on the Sun with open magnetic field lines. They are a source region of the solar wind, but how the wind emerges from coronal holes is not known. We observed a coronal hole using the Extreme Ultraviolet Imager on the Solar Orbiter spacecraft. We identified jets on scales of a few hundred kilometers, which last 20 to 100 seco…

Thin jets underlie the solar wind

The Solar Orbiter spacecraft was launched in 2020 by the European Space Agency to study how solar activity drives changes in the inner part of the heliosphere, the region that extends from the Sun to the surrounding interstellar medium. The Solar Orbiter is fitted with a suite of in situ and remote-sensing instruments that allow measurement of the…
