Solar Orbiter Reveals Sun’s Surface in Unprecedented Detail

---

Solar Orbiter is a collaborative mission between the ESA and NASA to study our Sun.

The spacecraft views some of the never-before-seen regions of the Sun, including the poles, and sheds new light on some of the little understood aspects of the star’s activity, such as the formation of the solar wind. It also provides data about the Sun’s magnetic field and how it arises.

Launched on February 10, 2020, Solar Orbiter carries ten scientific instruments, four of which measure properties of the environment around the spacecraft, especially electromagnetic characteristics of the solar wind, the stream of charged particles flowing from the Sun.

The new images of the Sun were taken when the spacecraft was at a distance of roughly 75 million km, half way between Earth and our star.
