It’s been about five years since scientists captured the first blurry image of a black hole. Using what they learned from that experience, they’ve teased out some more detailed images of the black holes at the centers of the Milky Way galaxy (top) and the M87 galaxy (bottom). The process of collecting the data for these images is interesting:
The only way to “see” a black hole is to image the shadow created by light as it bends in response to the object’s powerful gravitational field. As Ars Science Editor John Timmer reported in 2019, the EHT isn’t a telescope in the traditional sense. Instead, it’s a collection of telescopes scattered around the globe. The EHT is created by interferometry, which uses light in the microwave regime of the electromagnetic spectrum captured at different locations. These recorded images are combined and processed to build an image with a resolution similar to that of a telescope the size of the most distant locations. Interferometry has been used at facilities like ALMA (the Atacama Large Millimeter/submillimeter Array) in northern Chile, where telescopes can be spread across 16 km of desert.
In theory, there’s no upper limit on the size of the array, but to determine which photons originated simultaneously at the source, you need very precise location and timing information on each of the sites. And you still have to gather sufficient photons to see anything at all. So atomic clocks were installed at many of the locations, and exact GPS measurements were built up over time. For the EHT, the large collecting area of ALMA-combined with choosing a wavelength in which supermassive black holes are very bright-ensured sufficient photons.
While this idea may initially sound somewhat mundane, it is anything but. The result is surprising because Sgr A*’s mass is about 4.3 million times that of the Sun, while M87*’s is about 6.5 billion times that of the Sun. Despite the significant difference in mass between the two supermassive black holes, the fact that their magnetic fields behave similarly and are both well-organized is an incredible discovery.
The Vela Supernova remnant, located about 800 light-years away from Earth, is the cosmic corpse of a massive star that exploded 11,000 years ago. It is one of the closest supernova remnants to Earth and the perfect subject for the remarkable Dark Energy Camera.
The supernova is a vast cosmic structure about 100 light-years across. For context, one would have to travel around the Earth 200 million times to have traveled a single light-year.
I didn’t know what to expect from this 1937 video explanation of how wire photos were transmitted to newspapers, but a double stunt sequence featuring an airplane and a death-defying photographer was not anywhere on my bingo card. This starts kinda slow but it picks up once they get into the completely fascinating explanation of how they sent photographs across the country using ordinary telephone lines. The whole setup was portable and they just hacked into a wire on a telephone pole, asked the operator to clear the line, and sent a photo scan via an analog modem. Ingenious!
The Wikipedia page about wire photos is worth a read — French designers argued that the technology was responsible for an early form of fast fashion.
After World War II at haute couture shows in Paris, Frederick L. Milton would sketch runway designs and transmit his sketches via Bélinographe to his subscribers, who could then copy Parisian fashions. In 1955, four major French couturiers (Lanvin, Dior, Patou, and Jacques Fath) sued Milton for piracy, and the case went to the Appellate Division of the New York Supreme Court. Wirephoto enabled a speed of transmission that the French designers argued damaged their businesses.
“Like many amateur photographers, I do occasionally experiment with editing.” Well, I can’t resist the kerfuffle around what’s going on with Princess Catherine. Yesterday she posted a photo of herself with her family that turned out to have been edited, and today she apologized for “any confusion” it might have caused. (Shared presumably in part to dispel rumors about her health and whereabouts, the photo “fans [those rumors] instead,” per the NY Times.)
Last week, Nieman Lab ran a story on how unusual the Palace’s response to gossip surrounding the situation has been. And if you really want to get into the weeds, Nieman Lab’s editor-in-chief Laura Hazard Owen also just linked to a three-minute TikTok video proposing that the original Instagram photo was actually taken last November.

Alan Taylor is an under-appreciated internet curator. He’s been overseeing the photographic vibe over at The Atlantic’s In Focus for what seems like forever, and the quality is as high as ever. His latest post is 100 Years Ago in Photos: A Look Back at 1924.
The caption of that first photo reads:
Original caption from December 17, 1924: “Picks him up at 25 miles an hour! If the modern auto or truck hits you don’t worry. Equipped with this device you are simply given a free ride. This man even came from behind another car, was struck but not even scratched. The demonstration was given recently in Washington, D.C.”
Ansel Adams made a career of crafting photographs in exquisitely sharp focus and nearly infinite tonality and detail. His ability to consistently visualize a subject — not how it looked in reality but how it felt to him emotionally — led to some of the most famous images of America’s natural treasures including Half Dome in California’s Yosemite Valley, the Grand Tetons in Wyoming, and Denali in Alaska, the highest peak in the United States.

After hiking to a clifftop vantage point, Amit slowly crept closer. Using a wide-angle lens, he set the action of two clashing Nubian ibex against the dramatic backdrop. The battle lasted for about 15 minutes before one male surrendered and the pair parted without serious injury.
Sriram Murali captured the jungle lit up by fireflies:
Sriram combined 50 individual 19-second exposures to show the firefly flashes produced over 16 minutes in the forests of the Anamalai Tiger Reserve near his hometown. He watched as pinpoint flashes appeared in the treetops increasing in number as they spread down along the branches until something remarkable happened. Synchronising, they pulsated through the canopy like a wave — the pattern punctuated with sequences of abrupt on-off bursts in unison.
This dragonfly unexpectedly landed on the turtle’s nose but instead of the turtle snapping up the insect, it appeared to be experiencing pleasure from the interaction as they shared a moment of peaceful coexistence amid a swamp’s murky waters.
This is a video slideshow of some of the best images from the Mars missions — Spirit, Opportunity, Curiosity, and Perseverance — presented in 4K resolution at 60fps. These look amazing on the biggest hi-res screen you can find. (via open culture)
To Mr. Lignier, the parallel is obvious. “Digital and social media companies use the same concept to keep the attention of the viewer as long as possible,” he said.
Indeed, social media has been described as “a Skinner Box for the modern human,” doling out periodic, unpredictable rewards — a like, a follow, a promising romantic match — that keep us glued to our phones.
Or maybe being able to keep ourselves busy pressing buttons is its own reward. In a 2014 study, scientists concluded that many human volunteers “preferred to administer electric shocks to themselves instead of being left alone with their thoughts.” Maybe we would rather sit around and push whatever levers are in front of us — even those that might make us feel bad - than sit with ourselves in quiet contemplation.
That sea lion has the same energy as Aragorn at the Black Gate of Mordor, just before he whispers “for Frodo” and charges into the horde of orcs assembled before him. “For lunch.”
Anyway! You can check out the rest of the winners and finalists on the website.
Jan Erik Waider’s speciality is abstract landscape photography of cold climates. But in this series of projects, he takes a closer view of his subjects: Frozen Colors of Winter, Frozen Air, and Geometry of Ice.
You all know I love a good photography contest and it’s hard to pick favorites, but the Close-up Photographer of the Year competition is always up there for me. The results of this year’s contest are fantastic and it was difficult to pick out just a few of my faves above. From top to bottom: Chris Gug, Csaba Daróczi, René Krekels, Barry Webb. (via colossal)
Taken in Piemonte, Italy, the cathedral in the foreground is the Basilica of Superga, the mountain in the middle is Monviso, and, well, you know which moon is in the background. Here, even though the setting Moon was captured in a crescent phase, the exposure was long enough for doubly reflected Earthlight, called the da Vinci glow, to illuminate the entire top of the Moon.
The winners have been announced in the Natural Landscape Photography Awards for 2023. The competition rules are worth a look — they are pretty hardcore on the types of editing and retouching allowed. I posted some favorites above; from top to bottom by Jeroen Van Nieuwenhove, Xavier Lequarre, Blake Randall, and Jay Tayag. (via in focus)
[We] had to call the Royal Air Force each time we launched the drone, and spent months getting permits and approval to do this. Even then we still couldn’t fly it above the stone circle (for fear of damaging the stones).
While we were making these images, something that was always very present was the sound of the traffic on the nearby A303 highway, and I was certain that passing motorists would have been alarmed to see what looked like an alien spacecraft flitting around above the 5,000 year old megalith.
Using a custom hydrogen alpha solar telescope, Jason Kurth took a collection of high-resolution photographs of the recent annular solar eclipse and arranged them into an 8K video of the event. The level of detail here is incredible — you can see solar flares and features on the surface of the Sun pulsing and shifting as the Moon moves across it. You can see a bit of Kurth’s setup on Instagram.
The Nature Conservancy has announced this year’s winners of their annual photo contest. Collectively, the winning photographs “gave voice to nature and showed us the power and peril of the natural world”. As usual, I selected a few of my favorites and included them above. From top to bottom:
Jaime Daniel Fajardo Torres: “This is a species of spider known as ogre spiders, of the genus Deinopis. The photograph was taken at night in the middle of a mature forest in northern Ecuador in the tropical rainforest of the Ecuadorian Chocó, a place considered a hotspot. The spider photographed was generating its egg sac with its own web.”
HJ Yang: An orca attacks two seals in the morning on the beach.
Jeanny Tang: “The holes dug by fish for spawning can be seen after the pond has dried up.”
This is a heck of a time capsule: back in 2011, Chris Floyd photographed 140 people that he followed on Twitter over the course of a year and made a video featuring their portraits and audio of them “talking about Twitter and it’s effect on the way we communicate and form relationships in the modern era”. It’s almost quaint hearing people talk about the site in the time before Gamergate, 4chan, and other factors helped twist it into a very different place.
So proud to be one of the first photographers to reveal a new series of images captured on the Apple iPhone 15 Pro Max and celebrate its launch. “The Inner Landscape” is a series of six unearthly places that feel more intimate than epic, more ambiguous than explicit, making up a body of work that feels cohesive through its sense of connection and psychological space.
Santiago Borja is an airline pilot who takes stunning photos of storms and clouds from the flight deck of his 767. Definitely offers up a different perspective than the typical storm chaser photography. You can find his work on his website, on Instagram, and in book form.
From over 23,000 entered images, the judges in the Bird Photographer of the Year competition for 2023 have selected their winners and runners-up. I selected a few of my favorite images above; the photographers from top to bottom: Nicolas Reusens, Henley Spiers, and Gianni Maitan.
Eduardo Schaberger Poupeau for capturing a question mark on the Sun. I will never tire of looking at the detail of the Sun’s surface.
Angel An. “This is not, as it might first appear, an enormous extraterrestrial, but the lower tendrils of a sprite (red lightning)! This rarely seen electrical discharge occurs much higher in the atmosphere than normal lightning (and indeed, despite the name, is created by a different mechanism), giving the image an intriguingly misleading sense of scale.”
Mehmet Ergün. More Sun!
Marcel Drechsler, Xavier Strottner and Yann Sainty for their shot of the Andromeda galaxy.
The Andromeda galaxy is the closest spiral galaxy to our own Milky Way, and one of the most photographed deep-sky objects. Yet this particular photo, captured by an international trio of amateur astronomers, revealed a feature that had never been seen before: a huge plasma arc, stretching out across space right next to the Andromeda galaxy.
“Scientists are now investigating the newly discovered giant in a transnational collaboration,” explain the photographers. “It could be the largest such structure nearest to us in the Universe.”
The graceful winding arms of the grand-design spiral galaxy M51 stretch across this image from the NASA/ESA/CSA James Webb Space Telescope. Unlike the menagerie of weird and wonderful spiral galaxies with ragged or disrupted spiral arms, grand-design spiral galaxies boast prominent, well-developed spiral arms like the ones showcased in this image. This galactic portrait was captured by Webb’s Mid-InfraRed Instrument (MIRI).
In this image the reprocessed stellar light by dust grains and molecules in the medium of the galaxy illuminate a dramatic filamentary medium. Empty cavities and bright filaments alternate and give the impression of ripples propagating from the spiral arms. The yellow compact regions indicate the newly formed star clusters in the galaxy.
What an amazing, info-dense composite photograph taken by Casey Sims of the semi-finals of the men’s 110-meter hurdles at the 2023 World Athletics Championships in Budapest from last month. You can see and analyze the entire race, just from this one image. Eventual finals winner Grant Holloway is in lane 5 and led from start to finish.
In 2006, photographer Mark Preuschl recreated Georges Seurat’s famous impressionist painting A Sunday on La Grande Jatte in Beloit, WI with a group of volunteers. Here’s the original for reference:
In conceiving this tableau vivant, the organizers wanted to keep things modern. Thus, all participants are wearing contemporary clothes with umbrellas substituted in for the 19th-century parasols. Though the team was organized, they weren’t quite prepared for what mother nature threw their way the day of the shoot. Preuschl recalls winds of 20 to 25 mph coming off the river, as well as clouds that didn’t allow for the shadows they were so desperately looking for. Luckily, there was a window of about 25 minutes when the sun came out and cast those shadows.
He really couldn’t have scouted that location any better…it matches the original pretty well. Who knew you could find Belle Époque Paris in southern Wisconsin?
