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 European Space Agency 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 miles per hour.
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 behavior. These new, unique views from our Solar Orbiter mission are the beginning of a new era of solar science."
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 long, 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.

The European Space Agency and Dassault Aviation paving the way for potential collaborations
PRESS RELEASE June 20, 2025 The European Space Agency and Dassault Aviation paving the way for potential collaborationsThe European Space Agency (ESA) has signed a Letter of Intent (LoI) with Dassault Aviation, a French civilian and military aircraft manufacturer recognized worldwide for its excellence, underlying their common interest to develop a closer relationship. ESA, with its ambitious strategy for space exploration, Explore2040, is seeking innovative solutions for capabilities development to reach and return from Low Earth Orbit (LEO), Moon and Mars, and supports the advancement of selected critical enabling technologies to be used and demonstrated in particular in LEO, such as hypervelocity re-entry. Dassault Aviation, also a leader in aerospace engineering, is developing its space activities with a focus on the design of a reusable spaceplane based on lifting bodies shapes that bridge aeronautical and space technologies. Their interest in automated LEO platforms suitable for commercial and institutional markets, led them to develop a vehicle concept called 'Véhicule Orbital Réutilisable de Transport et d'Exploration (VORTEX)', designed for research in space, transport of cargo to and from space stations, and a range of in-orbit services. This project is based on a considerable expertise in spaceplanes having participated in numerous programmes like Hermes, NASA X-38 Crew Rescue vehicle, ESA Intermediate eXperimental Vehicle (IXV) demonstrator, and Airborne Reusable Hypersonic Experimental Vehicle (VEHRA) concepts. 'Dassault Aviation's decades of expertise in aeronautical and space systems, perfectly position them to pioneer critical space technologies', said Josef Aschbacher, Director General of the European Space Agency. 'With VORTEX, Dassault is contributing to strengthening European capacities and securing sovereign access to space in a strongly growing and competitive space sector. We look forward to combining our expertise and working hand-in-hand for a stronger Europe in space.' 'Our Vortex roadmap aims to strengthen Europe's essential sovereign capabilities and meet the new challenges of the space economy. This letter of intent is a perfect recognition of the complementary expertise of the European Space Agency and Dassault Aviation in the development of critical technologies and innovative space solutions,' declared Eric Trappier, Chaiman and CEO of Dassault Aviation. As such, the signatories of the LoI, have identified a mutual interest in developing a closer relationship with the potential to commonly derisking critical technologies as well as to further explore the potential for collaboration in areas such as LEO destinations and particularly around orbital vehicules. As such, both foresee an interest to cooperate on a scaled down suborbital version of VORTEX, serving as a testbed, with a focus on, but not limited to: Designing, testing and qualifying key technologies and components. New materials and integration processes. Assessing the feasibility to include future payloads in case of the integration of a dedicated bay on the end-product. This joint work will be based on exchanging relevant information and conducting studies or preparatory activities, to help establish respective roles and responsibilities in the realisation of potential joint activities, leveraging on each side's capabilities. 'Europe benefits from a wide range of diverse and complementary skills. Enlarging the European industrial base is key for new opportunities arising in Space Exploration, aiming at more autonomy,' said Daniel Neuenschwander, Director of Human and Robotic Exploration at ESA.

Start-up in bid to prove UK leads in space tech
A UK-built spacecraft engine that runs on metal is preparing for its first test in space, in a mission that could pave the way for longer-lasting, more flexible satellites. The plasma thruster, developed by Oxfordshire start-up Magdrive, heats tiny bits of solid metal into a hot gas to produce powerful bursts of thrust. In the future it could allow satellites to recycle parts of themselves, or space junk for fuel, but for now the metal is carried onboard. The launch, which is due from Kennedy Space Center in Florida, US, at 22:00 BST, is backed by the UK and European space agencies. Mark Stokes, chief executive and co-founder of Magdrive, said the mission showed what British innovation could achieve with the right support. "We've spent four years building something that breaks the mould," he said. "This launch isn't just about proving our tech – it's about proving the UK can lead in space." Dr Gianluigi Baldesi, from the European Space Agency, said the quick progress from project start to launch demonstrated the "bold" innovation it aimed to encourage. "In less than a year, we have gone from kick-off to launch," he said. Data from the test flight is expected in August and September.

Gaia, Europe's Galactic Cartographer, Is Gone But Not Forgotten
This observatory has probably been the most transformative astronomy project of the 21st century, but there's a good chance you've never heard of it. Just last week, for instance, the Hayden Planetarium at the American Museum of Natural History (AMNH) in New York City debuted a new 'space show' called Encounters in the Milky Way—and this often overlooked spacecraft is its scientific superstar. But you're more likely to know about actor Pedro Pascal's narration in the show than you are to be familiar with the single space mission that serves as the presentation's backbone. The observatory is called Gaia. And, like so many good things, you wouldn't really miss it until it's gone—and now it is. Launched in 2013 by the European Space Agency (ESA), it ceased operations this past March, when it used what little fuel it had left to steer into a graveyard orbit around the sun. From its station in a quiescent region of deep space more than 1.6 million kilometers from Earth, Gaia's mission was, in essence, quite simple: it was designed to give us a better sense of where we are—a celestial 'reference frame' on overlapping interplanetary, interstellar and intergalactic scales. To do that, it used twin sky-sweeping telescopes and three instruments, including a billion-pixel camera, to painstakingly measure the distances, positions, motions, and more of about two billion celestial objects, most of them stars in our own galaxy. It made some three trillion observations in all, producing (among many other things) the largest, most precise three-dimensional map of the Milky Way ever made. [Sign up for Today in Science, a free daily newsletter] 'Gaia was our best galactic cartographer, and I sometimes say that Encounters in the Milky Way is my love letter to it,' says Jackie Faherty, a senior research scientist at the AMNH, who curated the new space show and regularly works with Gaia data. 'It turns out you can learn a lot by determining where and how far off the stars are from you—and especially by how they are moving.... Gaia's creation of this map is something we all should celebrate because it's just as iconic and useful as the maps of Earth we all see in school or pull up on Google. Looking at it, you can find and explore all sorts of different things you want to know.' From Gaia's map, more than 13,000 peer-reviewed studies have already emerged, and many have concerned the fundamental structure and deep history of the Milky Way. Thanks to Gaia, scientists now can better gauge the amount of dark matter within our galaxy and have been able to track the Milky Way's growth and evolution across eons via relic streams of stars strewn from ancient mergers with other, smaller galaxies. 'Stars retain memories of their origins in their ages, motions and chemical compositions—all of which Gaia measured,' says Amina Helmi, an astronomer at the Kapteyn Astronomical Institute in the Netherlands. She and her colleagues used the mission's data to discover evidence of a major galactic merger that, some 10 billion years ago, shaped our home galaxy into the Milky Way we know today. 'With all that information, it was like a veil being lifted,' Helmi says. 'We could suddenly perform what's sometimes called 'galactic archaeology,' reconstructing the Milky Way's history to see when and how this merger happened with another, smaller galaxy that was about a third to a quarter of our galaxy's mass.... Gaia allows us to look billions of years into the Milky Way's history—before our solar system even formed—to see what actually happened back then, which is absolutely amazing.' Tracing perturbations from one more recent and ongoing merger, astronomers have even managed to reveal an apparent warp in the Milky Way's disk, offering a new twist—literally—on the classic image of our cosmic home. At smaller scales, the spacecraft has refined the orbits of more than 150,000 asteroids, surveilling hundreds of them to see if they have their own moons. It has spied hints of thousands of worlds and even a few black holes orbiting other stars. At larger scales, it has helped estimate the expansion rate of the universe, and it has also teased out the subtle tugging of the Milky Way's heart upon the solar system across tens of thousands of light-years. Gaia's sprawling cosmic reckoning is now a cornerstone for most state-of-the-art Earth- and space-based telescopes, which rely on the mission's target-dense celestial map to orient and calibrate their own observations and operations. Whether it's NASA's James Webb Space Telescope, ESA's Euclid mission, the ground-based, U.S.-built Vera C. Rubin Observatory or Europe's under-construction Extremely Large Telescope, practically all of the world's most exciting starlight-gathering telescopes will, in some sense, be guided by Gaia. And stunningly, the best is yet to come. More than two thirds of the mission's treasure trove of data is still under wraps. It is being prepared in a time-consuming process for two major upcoming milestones: about half of Gaia's total data are targeted for release next year, and the mission's full data are set to arrive no earlier than 2030. But because it didn't beam back images ready-made for lush wall posters and desktop backgrounds, Gaia was destined from the start to be 'criminally under-recognized outside astronomy,' says Mark McCaughrean, an astronomer and former senior adviser to ESA. 'And because Gaia provided utterly essential, if mundane, information such as precise stellar distances, it's been doomed with this curse of simultaneous ubiquity and obscurity as many people use its data but take it for granted as just 'coming from a catalog.'' Anthony Brown, an astronomer at Leiden University in the Netherlands, who leads the mission's data processing and analysis group, puts it most succinctly: 'For astronomers, Gaia has become almost like the air you breathe,' he says. At the heart of Gaia's mapmaking is a technique called astrometry, the measurement of celestial positions and motions in the plane of the sky. Paired with a phenomenon called parallax—the apparent shift of an object's position when viewed from two vantage points—astronomers can use Gaia for determining distances, too. You can see the parallax effect with your own two eyes: hold your thumb out at arm's length and watch as it appears to jump around as you blink one eye and then the other. The closer the object is, the bigger its displacement will be. And the bigger your baseline is between two vantage points, the smaller the displacement will be that you can discern. Your eyes have a baseline of about six centimeters; Gaia's was 300 million kilometers, set by the opposite sides of Earth's orbit around the sun. A Gaia predecessor, ESA's Hipparcos mission, used that same gigantic baseline to survey the sky from 1989 until it ran out of fuel in 1993. But the technology of the time limited Hipparcos's astrometric reckoning to a precision of about one milliarcsecond, with high-quality measurements only for about 100,000 objects within about 200 parsecs (650 light-years) of the solar system. (A single arc second is a very small angular slice of the heavens, making Hipparcos's milliarcsecond precision all the more noteworthy. The moon, for instance, takes up about 1,800 arc seconds in Earth's sky.) As impressive as Hipparcos was, Gaia shattered the records set by its precursor—although not without challenges, such as precision-threatening sprays of stray light that leaked around the edges of the spacecraft's sun shield and through a hole punched by an errant micrometeoroid. But ultimately, Brown says, Gaia's measurements achieved on the order of 100 times greater precision—reaching about 10 microarcseconds. And within the Milky Way, the spacecraft's view encompassed 100 times more volume and included 10 times more targets. The numbers underpinning Gaia are so alien to everyday experience that they border on nonsensical, says Michael Perryman, a former ESA researcher, who has served as project scientist for Hipparcos and Gaia and played a crucial developmental role for both missions. He likens Hipparcos's precision to discerning a second's worth of growth of a human hair from a distance of one meter. Gaia's 100-times-better view, he says, is more like measuring the width of a single hydrogen atom from the same distance. Another comparison involves the size of the two missions' datasets. When the Hipparcos team printed out its complete catalog, Perryman recalls, it comprised five thick volumes—almost enough to fill a single shelf of a bookcase. Printing out the full Gaia catalog with the same density of information per page, he says, would require about 10 kilometers of shelf space. 'The mind boggles,' he says. 'It's almost incomprehensible; these are numbers and dimensions we're simply not equipped to visualize, so even the analogies are very difficult to grasp.' The best example of the heights such precision can reach may be Gaia's tour de force determination of the solar system's acceleration with respect to a vast, sky-encompassing field of quasars. Quasars are the conspicuously bright cores of remote galaxies that harbor actively feeding supermassive black holes. As such, quasars are among the most powerful beacons astronomers can use to probe distant regions of the universe. Gaia pinpointed the positions of more than one and a half million of them to establish a fixed backdrop of sorts, against which various minuscule motions of our solar system or other nearby celestial objects could be seen. One motion Gaia managed to measure was an astonishingly small acceleration of just 0.232 nanometer per second squared—a continuous atom-scale deflection in the solar system's 220-kilometer-per-second trajectory through the Milky Way, attributed to the gravitational pull from our galaxy's center some 26,000 light-years away. Writ large, the displacement adds up to less than a meter per day—and essentially reflects the real-time sculpting of our galactic orbit as the solar system carves a path through the Milky Way's gravitational field. 'It's an almost circular motion around the galactic center, and it's directed toward the supermassive black hole there,' says astronomer Sergei Klioner of Germany's Dresden University of Technology, who led much of the work behind the measurement. 'No other observational data could come anywhere close to competing with Gaia here.... You often hear the term 'astronomical' in the sense of something being very large—but this is an example where Gaia has shown us something that's astronomically small.' Now that Gaia has gone dark, there's already talk of what comes next. 'Do we really need another astrometry mission?' asks Brown, who first began working on Gaia in 1997. 'Well, not immediately, but the extremely precise stellar reference frame it gave us—upon which many other observatories depend—will eventually deteriorate because all the stars are moving, right?' ESA is envisioning a follow-on mission, which would potential launching in the 2040s. This time that mission would be optimized for infrared observations to allow astronomers to see through the dust that otherwise clouds their view of the Milky Way's star-packed disk and galactic center. 'It's, in a way, wonderful but also a bit sad that people take Gaia for granted because, my God, it was a tough mission,' Perryman reflects. 'I don't feel sadness that it's gone; I'm just delighted and relieved it lasted so long, and I'm very conscious of how remarkable it is that we live in a time when society is willing to pool its resources to support such things, and we have the technology in place to do them. I hope this period continues—but I worry we've been taking that for granted, too.'
