The European Space Agency has achieved yet another 'first' for humankind by capturing the first photos of the Sun's south pole. These images were captured by the agency's Solar Orbiter spacecraft, and it gives us our first distinct look at the atmosphere of the Sun's southern pole.
When viewed from our little blue planet, the Sun appears as nothing more than a massive disc of light. However, thanks to the efforts of the Parker Solar Probe and other astronomical observations, we know that isn't really the case. Like the other planets in our solar system, the star that it all revolves around is massive, and made up of several different regions.

Further, because the star is made up of so much pure, raw energy, it's more like a roaring ball of power, with magnetic fields twisting and turning around it as it rotates. These fields are what help determine when the Sun sends solar energy ripping through space into our solar system, and understanding them is key to understanding our Sun's potential power.
We know that our Sun goes through a relatively quiet period, where the Sun's south and north pole are clearly defined. However, there's also a time where it's less stable, and the Sun is much more violent, with energy ripping off the surface of the star more frequently. Observing this has been difficult in the past, as we had no clear indicator of where the Sun's south and north poles were.
However, that changes now, thanks to the latest observations from the ESA's Solar Orbiter. Knowing where the Sun's north and south poles are will help us follow the magnetic fields as they go through a polar reversal, which changes how the energy flows on the surface of our star.
Now, researchers believe they may actually be able to watch where the flow of power and fluid transports bits of the Sun's solar energy to the poles. The goal of this observation is to help us come up with better computer models to estimate and predict when solar outbursts will occur.
Because solar storms can be so damaging to Earth's own magnetic field, having a good idea of where and when they might strike is key to protecting future space missions. However, there's still a lot of work to do if we want to be able to predict where the solar energy will erupt from. Until then, at least we have a good foundation to build off of.

See the Sun in a Way You've Never Seen It Before, From Above and Below
Every image you've ever seen of the sun is looking at its equator, because Earth's orbit sits there with a 7.25-degree tilt. That means humans have never had a good angle to view the sun's north and south poles until now. The ESA has released images of the sun's north and south poles, giving everyone their first glimpse at the top and bottom of our nearest star. The imagery was taken by the ESA's Solar Orbiter, which began its trek to view the sun's polar regions in 2020. To do this, the Orbiter engaged its boosters, made some adjustments and slingshotted itself around Venus at a staggering 27,000 MPH. Once it reached its destination, it took images using its Polarimetric and Helioseismic Imager (PHI), the Extreme Ultraviolet Imager (EUI), and the Spectra Imaging of the Coronal Environment (SPICE) instrument. "Today we reveal humankind's first-ever views of the sun's poles," said Professor Carole Mundell, ESA Director of Science, in a blog post. "The sun is our nearest star, giver of life and potential disruptor of modern space and ground power systems, so it is imperative that we understand how it works and learn to predict its behaviour. These new unique views from our Solar Orbiter mission are the beginning of a new era of solar science." See the Solar Orbiter's stunning sun view The sun's poles. ESA The images are viewable above or in a YouTube video on ESA's channels. In the video, you can see the view that we Earthlings generally see before the video transitions to the solar orbiter's viewpoint and zooms in so you can see the bottom of the sun in all of its hot, fiery glory. The video is only 50 seconds, but it's 50 seconds of footage that humans have never seen before. Most of the ESA's images and videos are of the sun's South Pole, but the blog post includes imagery of the North Pole as well. For the most part, scientists had no idea what to expect from the data, given that this is the first time any human had seen it before. The full dataset from the Orbiter's first pole-to-pole adventure is set to reach Earth by October 2025, which will give scientists much more to work with in terms of understanding how the sun works. Future orbits will include measurements from all 10 of the Orbiter's tools, so even more information is coming over the next few years.

Spacecraft unveils 1st-ever images of sun's south pole: 'Beginning of a new era'
Spacecraft unveils 1st-ever images of sun's south pole: 'Beginning of a new era' European Space Agency's Solar Orbiter, which launched from Florida in 2020, got a historic look at the sun's south pole. Plenty of spacecraft and telescopes have throughout the years been able to observe the sun up close – with plenty more missions on the way. In late-December 2024, NASA's Parker Solar Probe got closer to the sun than any spacecraft before it. Earlier that same month, the European Space Agency sent a pair of satellites toward the sun to create "solar eclipses on demand." And in March, NASA sent four small satellites on its PUNCH mission to study how the sun's outer atmosphere becomes solar wind. But no spacecraft has ever gotten a good look at either of the sun's poles. Until now. In March, a spacecraft captured the first-ever clear images of the sun's south pole, which the European Space Agency released Wednesday, June 11. 'We reveal humankind's first-ever views of the sun's pole,' Carole Mundell, director of science for the European Space Agency, said in a statement. 'These new unique views from our Solar Orbiter mission are the beginning of a new era of solar science.' Here's a look at what the Solar Orbiter captured, and why ESA officials believe it will help scientists better understand our life-giving host star. Solar Orbiter: Newly-released photos capture the sun in highest resolution ever ESA orbiter gets 1st look at sun's south pole Before you saw the picture above, any image you have ever seen of the sun was taken from around its equator. Why? Because Earth, like all the planets in our solar system, orbits the sun along a line across a flat, disc-shaped plane in the sky known as the ecliptic. That means all the spacecraft we launch into orbit tend to do so as well. But by tilting the Solar Orbiter's orbit out of that plane, the ESA was able to reveal the sun from a brand new angle. The process began in February 2025 when the Solar Orbiter passed closely by Venus for a gravitational boost that allowed the spacecraft to push itself out of the orbital plane to see the sun at a higher angle. Then on March 23, the Solar Orbiter whizzed by the sun at an angle of 17 degrees, as compared to the 7 degree-orbit of all the planets and other sun-observing spacecraft, to get some historic snapshots of the south pole. A few days prior, the Solar Orbiter was also able to view the sun from an angle of 15 degrees below the equator while using its fleet of on-board instruments to observe the sun in different wavelengths – including visible light and ultraviolet light. The images were taken as the sun's peak activity, known as its solar maximum, begins to wind down. ESA scientists believe that studying the sun's polar regions could be key to unlocking secrets about the sun's 11-year solar cycle, which can cause space weather that disrupts satellites and even causes northern lights to flourish. "The sun is our nearest star, giver of life and potential disruptor of modern space and ground power systems, so it is imperative that we understand how it works and learn to predict its behavior," Mundell said. What is the Solar Orbiter? The Solar Orbiter launched February 2020 from Cape Canaveral Air Force Station in Florida with 10 scientific instruments to study the sun. Its mission? Gather images of the sun from closer than any spacecraft before it and study the hot star's polar regions to understand things like the sun's atmosphere, its solar cycle and how solar wind forms. In November, the ESA released images the Solar Orbiter obtained in March 2023 that the agency said are the highest-resolution views of the sun's surface, known as the photosphere, to date. Solar Orbiter also got a look at sun's north pole According to the ESA, the best views from the Solar Orbiter are yet to come. In the coming years, the Solar Orbiter will continue to orbit around the sun at even higher angles, reaching as much as 33 degrees in July 2029. Scientists at the ESA also expect to receive images of the north solar pole by October that the Solar Orbiter has already taken. 'This is just the first step," Daniel Müller, Solar Orbiter project scientist for the ESA, said in a statement. "In the coming years, the spacecraft will climb further out of the ecliptic plane for ever better views of the sun's polar regions."

Solar Orbiter captures images of the sun's pole for the first time
The Solar Orbiter has been observing the sun since 2021, but it recently went on a side trip to Venus which significantly tilted its orbit and gave it a good view of the sun's polar region. That is how it was able to capture images that will historically be known as humankind's first-ever views of the sun's pole. All our galaxy's planets and the other spacecraft we've deployed orbit the sun around an imaginary ecliptic plane along the star's equator. But thanks to the Solar Orbiter's Venus flyby, it now has a view of the sun from below its equator, allowing it to see the star's southern pole clearly. The images you see above were captured from an angle of 15 degrees below the equator on March 16 and 17, but the probe has reached the 17 degree maximum angle it could achieve since then. To view this content, you'll need to update your privacy settings. Please click here and view the "Content and social-media partners" setting to do so. Three of the probe's instruments were responsible for the images. The Polarimetric and Helioseismic Imager (PHI) imaged the sun in visible light and mapped its surface magnetic field. Meanwhile, the Extreme Ultraviolet Imager (EUI) imaged the sun in ultraviolet light, and the Spectral Imaging of the Coronal Environment (SPICE) instrument captured light "coming from different temperatures of charged gas above the sun's surface, thereby revealing different layers of the sun's atmosphere." So what exactly was the Solar Orbiter able to observe at the sun's southern pole? Well, the pole's magnetic field, simply put, is a mess at the moment. See, the sun's magnetic field flips roughly every 11 years, and it's about to flip this year if it hasn't yet. Normally, a magnet has a clear north and south pole, but the orbiter's PHI instrument showed that both north and south polarity magnetic fields are present at the sun's south pole right now. "This happens only for a short time during each solar cycle, at solar maximum, when the Sun's magnetic field flips and is at its most active," ESA explained. After the flip, the magnetic field fixes itself so that the poles have single polarities. The process is gradual, however, and it will take five to six years to achieve solar minimum, wherein which the sun's magnetic field is at its most orderly. These solar cycles or regular magnetic field flips aren't fully understood yet, and the orbiter's observations could be the key to unlocking that knowledge. In addition, scientists used the orbiter's SPICE instrument to take Doppler measurements, or how fast clumps of solar material are moving. They then took that information to create a velocity map that shows how solar material moves within a specific layer of the sun. These measurements can show how the sun flings out particles into space in the form of solar winds, which is one of the orbiter's key goals.
