A stunning photograph has emerged from NASA's cameras of the Grand Canyon in Arizona, USA. The image showcases the canyon's unique topography, which is partially covered with a layer of snow. Snow is typical at high elevations during winter, and the South Rim and North Rim see average season totals of 58 inches and 142 inches, respectively.
However, this particular photo reveals an optical illusion known as relief inversion. The Sun is shining from below, creating shadows on the canyon walls that make it appear to be a mountain range rather than a deep gorge. This visual effect can deceive even experienced observers, making it essential for astronauts to consider relief inversion when interpreting images of the Grand Canyon.
Astronauts captured these breathtaking photographs of the Grand Canyon using a Nikon Z9 digital camera and a focal length of 400 millimeters on January 26, 2026. The images were taken by Expedition 74 crew members as part of their Earth observations mission. They can be viewed on NASA's Gateway to Astronaut Photography of Earth website.
Additionally, there are links to visit the Grand Canyon during winter, learn about weather and climate conditions at the park, explore previous NASA photos of the Grand Canyon under snow, and discover more information about relief inversion.

This photo is insane! I've always loved the Grand Canyon but never saw it looking like this before. The way the shadows are playing tricks on you makes it look like a mini mountain range 
. And can you imagine being an astronaut capturing these shots? Mind blown 
. Relief inversion, huh? Never heard of that term but now I'm curious to learn more about it. 
It's amazing how NASA is sharing all this info and even has tips on how to visit the Grand Canyon during winter. Maybe one day I'll make it out there 
.
! It's crazy to think that the Sun was shining from below to create this optical illusion 
. Relief inversion is like whoa, it makes you realize how powerful light can be in manipulating our perception of the world 
. And I'm loving the fact that these astronauts got to capture such an amazing shot using a Nikon Z9 camera 
. It's giving me all the feels just looking at it! 
Can we get more pics like this? 
Relief inversion, who knew? It's like the universe decided to play a trick on us with this gorgeous image. And can you imagine being an astronaut, looking at this photo and being like, "Whoa, we actually captured that?" 
The fact that they used a Nikon Z9 camera and got these incredible shots is just mind-blowing!

did u know that relief inversion is like, a thing?

They're trying to distract us from something... or someone? The fact that they're using a Nikon camera on a space mission is suspicious, don't u think? 
But seriously, what are we supposed to think with all these pics of the same old place? Are they hiding something from us? Maybe there's a secret underground tunnel system or something... 
The truth is out there, folks! 
And can we please go visit the Grand Canyon already? 
. And can you believe the optical illusion they're describing? It's like the whole canyon is transformed into a mountain range - so cool 
. By the way, have you heard anything about the new moon missions coming up? 
. Love how you can click on those links to learn more and plan a trip to see the Grand Canyon in winter 
The fact that it took an astronaut to capture this image, though, makes me appreciate their skill even more - they're like superheroes with cameras! 
This relief inversion effect is crazy and I'm loving the way it's showcasing the Grand Canyon's unique topography. Can't wait to see more pics from the NASA crew 
. 
.
, right? And can you believe it took an optical illusion to reveal the actual shape of the canyon? Mind. Blown. 
. It's amazing how much you can learn from just one image, right? And can't wait to see more pics like these!

IT'S PRETTY COOL HOW THE SUN'S POSITION CAN CREATE THIS KIND OF ILLUSION AND MAKE THE CANYON LOOK LIKE A MOUNTAIN RANGE INSTEAD OF A DEEP GOUGE. IT'S JUST AMAZING TO THINK ABOUT HOW MUCH WE STILL HAVE TO LEARN ABOUT OUR PLANET, ESPECIALLY FROM UP THERE IN SPACE
