Sun's Poles Have Flipped: Solar Orbiter Captures Historic First Look at South Pole

The Solar Orbiter spacecraft has captured the first-ever detailed images of the sun's south pole, revealing a region in turmoil during the solar cycle's peak.

A spacecraft has captured the first-ever detailed images of the sun's south pole, revealing a region in turmoil during the solar cycle's peak. The sun, located about 93 million miles away, is experiencing extreme activity as it reaches the climax of its 11-year solar cycle. This cycle, similar to Earth's storm seasons, begins and ends with calm periods of fewer flares and sunspots, but reaches a chaotic peak before subsiding. The Solar Orbiter, a joint mission between the European Space Agency and NASA, achieved this unprecedented view in March by tilting its trajectory. While previous spacecraft have focused on the sun's equatorial regions, the Solar Orbiter's unique angle revealed the southern region in detail. The images showed the sun's poles had flipped, a rare and temporary phenomenon during the solar maximum, where both poles occupy the same position before the magnetic field reorganizes. Scientists are still unsure how this magnetic reversal occurs, but the Solar Orbiter's timing is ideal for studying the process. Launched in 2020, the spacecraft used a gravity assist from Venus in February to shift its trajectory, enabling it to capture these historic images. Unlike previous missions, such as the now-defunct Ulysses, the Solar Orbiter is equipped with cameras and instruments to study the sun's magnetic field, ultraviolet emissions, and charged gas temperatures. Understanding the solar cycle is crucial for predicting space weather events that can disrupt power grids, satellites, and navigation systems. The Solar Orbiter's mission aims to uncover the mysteries of the sun's internal dynamics, particularly at the poles, which are believed to hold the key to understanding the solar cycle. Over the next few years, the spacecraft will tilt further, reaching 33 degrees by 2029 to fully map both poles.
