NASA / ESA's Solar Orbiter spacecraft observed the Sun in unprecedented detail, showing a unique image of the star's south pole around March 30, 2022.

ESA and NASA have now presented the images, which were captured using the Extreme Ultraviolet Imager (EUI) at a wavelength of 17 nanometers.

It should be noted that the shades of yellow you see in the image have been artificially added by the space agencies so that we can see what surprised the spacecraft.

The images in the video above are the same as those captured by Orbiter, but colors were added because the original images were almost undetectable to the human eye.

Astronomers want to exploit the Sun's poles, thanks to much scientific evidence that could gather data on the magnetic fields that create the temporary and great active regions of the Sun.

In the image, you can see the bright areas of the mysterious south of the Sun, where the spacecraft captured closed lines of the magnetic field, a kind of loops of magnetism that we see in the many images of the Sun. In this area, the particles are difficult to escape from the Sun, resulting in being caught back by the star, emitting ultraviolet radiation, which Orbiter's instrument saw.

Also, the dark areas in the south of the Sun are spectacular in this image, showing the open solar magnetic field, where the gases can escape into space.

These gases that come out of the dark side later form the solar wind that sometimes ends up hitting the Earth, creating telecommunications disruptions, affecting satellites, also affecting electricity networks for a medium or long period of time.

After 2025, when the spacecraft Orbiter will use the gravitational pull of Venus to tilt, space agencies expect a deeper view of the Sun from bottom to top.
