Observations from the spacecraft have revealed the presence of both Arctic and Antarctic magnetic fields in the Sun’s southern hemisphere. This complex magnetic configuration is predicted to persist only temporarily during the solar maximum before undergoing a magnetic field reversal.
The European Space Agency (ESA) states that as the Sun transitions to its quieter solar minimum phase, this accumulation at the poles should occur gradually over time.
“The precise mechanics of this accumulation are still not fully understood. However, the Solar Orbiter has reached high latitudes at a crucial time to observe the entire process from a unique vantage point,” explains Sami Solanki, director of the Max Planck Institute for Solar Systems Research in Germany and a scientist working with the Solar Orbiter project.
While scientists have previously captured close-up images of the Sun, these were primarily taken from the Sun’s equator by various spacecraft and observatories.
The Solar Orbiter’s mission included a journey through the cosmos, featuring a close flyby of Venus, which allowed the spacecraft to tilt its orbit for a better view of the Sun’s higher latitudes.
The recently released image was captured in late March when the Solar Orbiter was positioned 15 degrees below the Sun’s equator, shortly followed by another observation at 17 degrees below the equator.
“We had no clear expectations for these initial observations. The Sun’s polarity is truly uncharted territory,” Solanki stated, as mentioned in a statement.
Launched in February 2020, the Solar Orbiter mission is a collaborative effort led by Europe in conjunction with NASA.
In the coming years, the Solar Orbiter’s trajectory is expected to tilt even more, providing increasingly direct views of the solar polar regions. According to ESA, the most impressive observations may still be on the horizon.
“This data will transform our understanding of solar magnetic fields, solar winds, and solar activity,” states Daniel Muller, the Solar Orbiter project scientist at ESA.
