Thanks to its newly tilted orbit around the Sun, the European Space Agency-led Solar Orbiter spacecraft is the first to image the Sun’s poles from outside the ecliptic plane. Solar Orbiter’s unique vi...

Groundbreaking observations map chaotic patchwork of magnetic activity at pole, said to be key to understanding how sun’s field flips The sun’s uncharted south pole has been revealed for the first time in striking images beamed back from the Solar Orbiter spacecraft. The joint European Space Agency (ESA) and Nasa mission swooped below the planetary plane and, for the first time, captured the sun’s mysterious polar regions. The groundbreaking observations also mapped a chaotic patchwork of magnetic activity at the sun’s pole that scientists say is key to understanding how the sun’s field flips roughly every 11 years.
