Introduction to the Sun’s South Pole
The south pole of the sun was seen for the first time from outside the ecliptic level in unprecedented images sent back to Earth by a spacecraft. The Solar Orbiter spaceship drove 15 degrees below the solar equator of the sun to record the pictures in mid-March.
The Spacecraft’s Journey
It is only the second craft to have gone over the poles of the sun, with the previous one being the ESA and NASA’s Ulysses from 1990-2009, which did not have the ability to take photos. The Solar Orbiter started its journey in 2020 from Florida and will continue its orbit around the sun until Christmas Eve 2026.
New Era of Solar Science
The director of the European Space Agency described the images as "Humankind’s first views of the Sun-Pol" and marked the beginning of a "new era of solar science". The sun is our nearest star, the encoder of life, and the possible disruptor of modern spatial and soil power systems, making it essential to understand how it works and learn to predict its behavior.
Unique Perspective
Earlier pictures of the sun were taken from the equator because the Earth, other planets, and operational space vehicles circle the sun in a flat disc called the ecliptic level. The Solar Orbiter has revealed the star from a completely new perspective due to the tilt of its orbit from this level. The best views are yet to come as the spaceship will continue to tilt.
The Sun’s Poles
In contrast to Earth, which has fixed North and South Poles, the sun’s equivalents fly in an 11-year cycle. This is because its equator turns faster than its poles, making it an unstable object. The sun is currently on what is called "solar maximum" when the star builds up to the polar flip, and its spots and solar flares are most active.
Future of the Solar Orbiter
The pictures from the recent journey of the Solar Orbiter show a fragmented mosaic of north and southern polarity in the sun. The spacecraft will fly past Venus in 2029, providing more opportunities to study the sun and its behavior. The sun will reach its "solar minimum" in five or six years, when its magnetic activity is lowest, and the Solar Orbiter will continue to provide valuable insights into the sun’s workings.
