Incredible new image shows the magnetic fields at the edge of the M87 black hole

The Event Horizon Telescope (EHT) collaboration has published a new view of the black hole at the center of the M87 galaxy. The EHT published the first-ever image of a black hole in 2019. This time, the image shows the black hole in polarized light, which shows the magnetic field surrounding the black hole. This marks the first time astronomers have been able to measure polarization this close to the edge of a black hole.

Polarization is a signature of magnetic fields, and being able to observe the magnetic fields provides scientists important new information and helps explain how the M87 galaxy launches energetic jets from its core. Monika Mościbrodzka, Coordinator of the EHT Polarimetry Working Group and Assistant Professor at Radboud Universiteit in the Netherlands, said, ‘We are now seeing the next crucial piece of evidence to understand how magnetic fields behave around black holes, and how activity in this very compact region of space can drive powerful jets that extend far beyond the galaxy.”

”A view of the M87 supermassive black hole in polarized light: The Event Horizon Telescope (EHT) collaboration, who produced the first-ever image of a black hole released in 2019, has today a new view of the massive object at the center of the Messier 87 (M87) galaxy: how it looks in polarized light. This is the first time astronomers have been able to measure polarization, a signature of magnetic fields, this close to the edge of a black hole. This image shows the polarized view of the black hole in M87. The lines mark the orientation of polarization, which is related to the magnetic field around the shadow of the black hole.’ Image and caption credit: EHT Collaboration. Click to enlarge.

In 2019, when EHT scientists released the first image of a black hole, they had not finished digging through the data collected in 2017 on the supermassive object at the center of the M87 galaxy. Since then, researchers have discovered that a ‘significant fraction’ of the light around the M87 black hole is polarized. ”This work is a major milestone: the polarization of light carries information that allows us to understand better the physics behind the image we saw in April 2019, which was not possible before,’ says Iván Martí-Vidal, also Coordinator of the EHT Polarimetry Working Group and GenT Distinguished Researcher at the Universitat de València, Spain. Martí-Vidal continues, ‘Unveiling this new polarized-light image required years of work due to the complex techniques involved in obtaining and analyzing the data.”

Light is polarized when it travels through certain filters, like a circular polarizing filter used on a camera lens to reduce reflections and glare or when light is emitted in hot regions of space that are also magnetized. EHT writes, ‘In the same way polarized sunglasses help us see better by reducing reflections and glare from bright surfaces, astronomers can sharpen their vision of the region around the black hole by looking at how the light originating from there is polarized. Specifically, polarization allows astronomers to map the magnetic field lines present at the inner edge of the black hole.’ The new polarized images are critical to understanding how the magnetic field surrounding the black hole allows the black hole to consume matter and send out jets of energy.

The energy that emerges from M87’s core extends at least 5,000 light-years from its center. Scientists have been working to understand why some matter near the black hole is consumed by it, while other particles escape just before entering the black hole and form the observed jets of energy shooting from the black hole. The new image allows scientists for the first time to look at the region just outside the black hole where there’s a mix of matter flowing in and being ejected from the black hole.

” The observations suggest that the magnetic fields at the black hole’s edge are strong enough to push back on the hot gas and help it resist gravity’s pull. Only the gas that slips through the field can spiral inwards to the event horizon,’ said Jason Dexter, Assistant Professor at the University of Colorado Boulder, USA, and coordinator of the EHT Theory Working Group.

Canon makes Super35 global shutter sensor available to third parties


Canon’s LI5070SA sensor delivers 4K at up to 60p with no rolling shutter, with Canon suggesting ‘Cinema’ as one of its potential applications.

Canon has made a 4K/60-capable Super35 (∼APS-C) video sensor with global shutter available to third-party buyers.

The 10.3MP sensor added to the product page of its industrial equipment and semiconductor business unit is 27.4 x 15.3mm, making it a 1.34x crop, relative to a full-frame stills camera, but in a roughly 16:9 aspect ratio.

Its 4288 x 2398 pixel count is clearly designed for delivering 4K footage. We’d usually expect Canon to have already offered it in a camera, if it planned to, before offering it to external users.

Canon sold a 4K/60 Super35 ‘GS’ global shutter version of its EOS C700 camera, back in 2017, though available specs suggest its sensor was slightly smaller, so presumably wasn’t the same as the one now being offered to external companies. Notably, Canon claimed its dynamic range was one stop lower than the progressive scan Super35 chip in the regular C700 model. There’s still a chance this new chip will underpin a successor to the C700 GS.

At present, we’re not aware of any other consumer camera maker using Canon sensors. Specialist industrial / security camera makers such as Illunis have used its sensors to make high-speed and high-resolution cameras for applications such as aerial photography and machine vision applications, but we’ve not seen its 120MP or 250MP APS-H chips in consumer cameras, including those from Canon itself.

Canon said it was developing a DSLR based on its 120MP sensor, back in 2015. Prototypes based on EOS 5DS bodies appeared at trade shows, but no final product ever emerged.

Canon’s semiconductor business also offers a “full-frame” global shutter sensor. Again this has a roughly 16:9 aspect ratio and proposed uses include microscopy, factory automation and traffic surveillance. This sensor has been available since early 2023.

Gear of the Year – Mitchell's choice: ThinkTank Retrospective 30 V2

Gear of the Year – Mitchell's choice: ThinkTank Retrospective 30 V2


The Retrospective 30 V2 is a big ‘ol bag.

The ThinkTank Retrospective 30 V2 is not a new product by any means, but it’s new to me. Earlier this year, I went looking for a camera bag to replace the one I had since high school and landed on the Retrospective 30; the largest option in ThinkTank’s well-known lineup of canvas shoulder camera bags.

While anyone can make a messenger bag with a few dividers and call it a day, it feels like this bag was really designed and refined by and for photographers. All its velcro flaps can be covered or tucked away to silence them if you don’t want to draw attention to yourself while shooting on the street or at an event like a wedding. The top can be zippered closed for maximum protection or left open to let you quickly access gear, and it has what I think is just the right ratio of open space to built-in organization.

Some of the velcro patches have covers to keep you from ruining a quiet moment by ripping them open.

There are also subtle touches that I’ve found really useful: one of the front pockets has a bright red fabric loop that I clip my keys to so I always know where they are, the water bottle pocket can be cinched tight when you’re not using it and there are plenty of places to hook carabiners onto if I need to hang additional gear on the outside of the bag.

I also just like how it looks. The olive green fabric matches the antique-looking metal hardware well.

My favorite thing about this bag, though, is that it’s monstrous. It’s the station wagon – nay, Honda Odyssey – of messenger-style camera bags. I’ve used it to carry two camera bodies, a few lenses, a 14-inch MacBook Pro, an iPad, and a bunch of other bits and bobs like a notebook, an army of SD cards, a Clif bar or two, power adapters and rain jacket. Is that a sign of overpacking? Perhaps, but it’s part of the job; I’m frequently testing out one camera for a review and using another to shoot a sample gallery of some variety.

It may look like there are three lensed cameras in here – a Nikon Z8, Canon EOS R7 and Panasonic S9 – but there are actually four; a Fujifilm X-M5 is hiding out in a compartment under the Z8’s grip.

Even when my camera load isn’t as heavy, I’ve found the Retrospective 30 useful as a commuter. I live in Spokane, Washington, but travel to DPReview’s offices in Seattle relatively frequently. Because I keep my entire photographic life in it – my SD cards, various cables, white balance cards and rolling shutter tester – I can just pick it up and go without having to run around making sure everything I’ll need for the next week is packed.

I took a bit of a chance buying this bag: DPReview was sending me to Japan as a freelancer to cover what ended up being the Panasonic S9 announcement, and I knew the Lowepro bag I’d gotten with my first camera in high school was on its very last legs. I hoped to turn reviewing cameras into my full-time job, but I wasn’t 100% sure I was cut out for it.

If it turned out I wasn’t, the 30 would be way larger than I’d ever need; my personal camera consists of a Fujifilm X-T3 and two lenses, which would get absolutely swallowed by this bag. But if I did end up at DPReview, I worried that a smaller bag might not be able to carry all the gear I assumed I’d be carting around.

I was also concerned about the price at the time: at $240, it’s far from the spendiest bag out there, but I still didn’t feel great telling my wife that I wanted to spend that much on anything when I’d been largely unemployed for the last year – I’d quit my job as a news writer at The Verge in April 2023 to hike the Pacific Crest Trail. I spent some time working at a ski shop after I got back and did various odd jobs, but it’d been a long time since I’d meaningfully contributed to our household’s budget.

But I went for it anyway; the prospect of going on a press trip and juggling cameras in a backpack that’s not at all designed for them seemed like a nightmare. And obviously, it worked out: I’m working at DPReview now, and am reminded pretty much every day that it was a good idea to get something with this much capacity.

Despite its carrying capacity, the Retrospective 30 is a reasonable size to carry around on a photo walk.

Of course, I have a few nitpicks. No bag is perfect, which is why the market for them is nearly infinite. I haven’t figured out a graceful way to attach a tripod to it, even one as small as the Peak Design Travel model, the main zipper can be a bit hard to start closing if it’s all the way open, and I needed a tutorial video to figure out how to use the included rain cover. I’d rather the bag’s top flap was made out of waterproof material, though the canvas alone has been enough to protect my gear through short walks in light rain – phew!

The bag can also rub a bit uncomfortably on my hip when it’s fully loaded, but I suspect that’s more of a limitation with the messenger bag form factor as a whole. Realistically, if you’re carrying over 7kg (15+lbs) of gear, you should be doing it on your back, not slung over one shoulder.

Despite my complaints, I still love this bag, and I suspect I’ll continue using it for years to come. The same’s true for the job, by the way – and if I’m lucky enough for that to happen, I’ll have the Retrospective 30 as a reminder of where it all began.

Magic skies: See the Northern Lights Photographer of the Year winning photos


Northern Lights Photographer of the Year winners

Capture the Atlas has announced the winners of its 2024 Northern Lights Photographer of the Year awards in the seventh edition of its annual photo contest.

This year was an exciting year for aurora photography – both the aurora borealis and the aurora australis – as we close in on the solar maximum of the current solar cycle. Throughout 2024, increased solar activity has resulted in aurora being visible further away from the poles than in recent years, which can be seen among the winners.

This year, the competition awarded 25 photos from photographers representing 15 nationalities. We’ve picked our ten favorite images from the set to share here.

Want to be ready to photograph the aurora if it suddenly becomes visible in your area? Read our article on how to photograph the northern lights to learn how.

Location: Crater Lake National Park, USA

Caption: May 10, 2024, began like any other new moon cycle for me. I was shooting at one of my favorite spots along the Sonoma coastline. Around 2:30 a.m., I was surprised to feel my phone buzz with a notification, as my location had sporadic cell coverage. The alert was one I never expected—and will never forget! A fellow Sony Alpha photographer, who was in Nepal at the time, messaged me: “Get as far north as you can by sunset, it’s going down tonight!” A historic geomagnetic storm, possibly peaking at G5, was predicted.

I immediately drove home to grab my Atlas pack full of cold weather gear. My gut told me to head to Crater Lake National Park in Oregon. Shortly into the drive, I learned the CLNP Rim Road was completely closed due to 7 feet of recent snowfall. Fortunately, I was prepared for deep snow conditions and pressed on.

Confident and armed with snowshoes, I settled on a spot along the South Rim, east of the Crater Lake Lodge, which was closed due to the extreme snow levels. My image, “Carpe Diem,” reflects the magnificent display of geomagnetic energy that weekend, set against the iconic and unforgettable alpine landscape.

Location: Arizona, USA

Caption: It’s not every day that the Northern Lights make it as far south as Southern Arizona! I’ve been captivated by the aurora ever since I first saw it in Iceland in 2018, so when I heard there was a chance to witness it here, I didn’t hesitate to grab my gear and head into the desert with a couple of friends.

My expectations were low, but the show completely exceeded them! As soon as we stepped out of the car, we could clearly see a pink glow on the horizon, occasionally pulsing with shimmering pillars as the night went on. I achieved a photography goal I never imagined I’d accomplish: capturing the aurora shining over the beautiful saguaros of the Sonoran Desert.

Location: Rybachy Peninsula, Russia

Caption: After a melt, we had a flash freeze with extremely cold temperatures and a clear blue sky. I was driving by a ditch on the side of a road that had been filled with water and had to stop and look (as we photographers do, can’t pass a ditch without investigating). This is what I found. Great textures and patterns, tones and flow, with lovely graphic lines creating a dynamic, abstract designs. I love this type of work – it’s so much fun, yet challenging to find just the right composition.

«Magic of the North» – Josh Beames

Photographer: Josh Beames

Location: Iceland

Caption: I’ve dreamed of capturing this shot for years, and this year, everything aligned perfectly! During my annual Iceland workshop, our group witnessed the sheer power of nature as Iceland’s most recent active volcano erupted just days before.

After spending hours shooting and soaking in the incredible scene, we started to wrap up and head back to the car. Then, to our amazement, the Northern Lights began dancing across the sky! I quickly launched the drone, sending it on a mission to capture this wild spectacle.

Navigating through the wind, heat, and low visibility surrounding the volcano, I managed to capture a vertical panorama just as the volcanic smoke and ash shifted to the side. Moments later, the dreaded battery warning sounded, and I began the tense journey back. By this point, the wind had really picked up, and I honestly thought the drone was a goner… but with only 1% battery left, it somehow limped back to safety!

Devil’s Lights: Forest Barkdoll-Weil

«Devil’s Lights» – Forest Barkdoll-Weil

Photographer: Forest Barkdoll-Weil

Location: Wyoming, USA

Caption: May 10, 2024: Aurora forecasts promised an incredible display, so I drove to Devils Tower, Wyoming, to witness the event. The solar storm delivered, reaching a historic KP9, with auroras visible worldwide. As the vibrant lights danced overhead, my father was undergoing emergency surgery two thousand miles away in Maine. It was a surreal night—awed by the celestial beauty above, yet grappling with worry for my dad.

The aurora offered a strange sense of comfort amidst the turmoil, grounding me in the moment as I captured this incredible phenomenon. My father, a photographer for over 50 years and the person who introduced me to this art, thankfully survived surgery and recovered after several days in the ICU. Although he missed this display, six months later, on October 10, we shared an even stronger solar storm together as a family—a memory I’ll always treasure.

Photographer: Matt Haynie

Location: California, USA

Caption: After finally capturing the elusive Northern Lights in mid-latitudes on May 10th, 2024, I was hooked. I realized there was more to predicting the aurora’s appearance than just relying on the KP forecast, so I learned how to read the charts that determine when the lights can reach mid-latitudes.

This photo is from the sixth time I’ve had the opportunity to capture them since that unforgettable night. Lassen Volcanic National Park, in Northern California, was the best option, as smoke and clouds threatened to obscure views in most nearby locations. I stayed on top of a ridge until 3 a.m., enduring frigid winds that cut through my layers, but witnessing two significant substorms made all the discomfort worthwhile.

Paddling Under the Aurora: Herry Himanshu

«Paddling under the Aurora» – Herry Himanshu

Photographer: Herry Himanshu

Location: Banff National Park, Canada

Caption: I live in Saskatchewan, Canada, so I’ve seen and captured the aurora hundreds of times before, but that night in Banff National Park, Alberta, was unlike any other.

As luck would have it, I was in Banff for a wedding that weekend when massive CMEs were predicted to hit Earth directly. As soon as it got dark, the aurora came out swinging, with vivid hues of reds, pinks, and purples dancing across the sky.

I had three camera setups running timelapses in different directions, but even that wasn’t enough. One brave friend took a standup paddleboard out on the lake and modeled for us beneath the insane light show. She was the perfect complement to the aurora and the mountainous landscape.

We were all in pure disbelief at the colors and patterns unfolding above us. Those shared moments of joy are what I’ll remember forever. I stayed up all night, driving hundreds of kilometers through Banff to iconic spots, capturing some of my best photos and timelapses ever.

Cosmic Explosion: Uroš Fink

«Cosmic Explosion» – Uroš Fink

Photographer: Uroš Fink

Location: Istria, Croatia

Caption: On the night of the Perseid meteor shower, I was treated to a “multi-course menu” of the night sky. I captured the Milky Way arch with Orion, the Aurora (a first for me), the Zodiacal light, and the Perseid meteors. As if that wasn’t enough, the sky gifted me with one of the most stunning greenish airglows I’ve ever seen. Oh, and I almost forgot to mention the close conjunction of Jupiter and Mars, right along the path of the Zodiacal light.

In the center of the panorama is the Cap Marlera lighthouse, built in 1880 at the southeastern tip of the Istrian Peninsula. The rugged coastline, at the entrance to Kvarner, attracts fish and dolphins. This area is also home to the Mediterranean bear, though I didn’t have the pleasure of meeting one.

Meteors rained down throughout the night, and I captured 75 of them using three cameras. I used the RegiStar software to seamlessly insert the meteors to the panorama in the exactly same spots as they appeared in the sky this night.
It was an extraordinary, perhaps once-in-a-lifetime event, and I’m grateful and happy to have been part of it.

Location: Patagonia Fjords, Chile

Caption: I’m not sure if an aurora had ever been recorded in Patagonia before, but we got incredibly lucky on the night of May 10, 2024, when a G5 storm hit. We were camped on an iceberg beach, deep in the wilderness of the Patagonia Fjords, when the incredible display unfolded.

28° Aurora: Efrén Yanes

«28º Aurora» – Efrén Yanes

Photographer: Efrén Yanes

Location: Tenerife, Spain

Caption: The night of May 10th was one of the most unforgettable moments since I became a photographer. I went to Teide National Park in Tenerife with the intention of capturing a circumpolar shot with the endemic tajines in bloom. After setting up my camera and finding the perfect composition, I hit the shutter. To my surprise, the camera screen showed a strange red color on the horizon. It wasn’t light pollution, but something I had never seen before.

Suddenly, I remembered hearing about a recent large-magnitude solar storm and the possibility of Northern Lights at lower latitudes. My heart raced as I scrolled through social media and saw others sharing photos of the Aurora from the Iberian Peninsula. I realized I was witnessing this extraordinary event from the Canary Islands. It was a magical experience that happened entirely by chance, and I feel incredibly lucky to have been a part of it.
