NASA's Juno spacecraft made a stunning flyby of Jupiter's volcanic moon Io on December 30, 2023, capturing breathtaking imagery that sheds new light on the moon's surface. The JunoCam instrument snapped this remarkable picture from an altitude of approximately 930 miles (1,500 kilometers) above Io, revealing the night side of the moon in unparalleled detail.
As Io's dark side was bathed in "Jupitershine," the sunlight reflected off Jupiter's surface illuminated its volcanic terrain. This striking phenomenon showcases the unique dynamics at play between the two celestial bodies. The image is a testament to the Juno spacecraft's advanced capabilities and provides scientists with a wealth of data for further study.
The NASA Science Image of the Month for October 2025 features this remarkable image, which will be shared across various platforms and online resources. Fans of space exploration can now download desktop wallpapers and engage with educational content related to Io and its fascinating volcanic landscape. The high-resolution image, processed by Emma Wälimäki, has been made available under a Creative Commons license for further use and analysis.

Io looks like a total volcano world! Can't believe we're finally getting some decent pics of it. That "Jupitershine" thing is wild, I mean who needs sunlight when you've got Jupiter's brightness? The details on Io's surface are insane too, like they actually captured the lava flows and volcanic vents 
Would love to see more vids from Juno's camera, this is just a tease 
and i love that they made this pic available under creative commons so anyone can use it & study it further 
and it's so much fun! i was thinking about this the other day when i saw that pic from juno and it reminded me of those fireworks at night. you know how everything lights up in the sky and its all vibrant colors? it's kinda like that with the jupiter thing too, but on a whole different scale 
just saw that NASA's Juno spacecraft caught some insane pics of Jupiter's moon Io! I mean, 930 miles above the surface? That's like flying over NYC in a plane, lol 
️! Anyway, did you know Io is actually super volcanically active with around 400 major volcanoes and 175 active volcanoes?! 
And can we talk about the Jupitershine phenomenon? That's some wild lighting, fam! 
The JunoCam instrument is basically a space-grade camera, capturing 360° views of Io in stunning detail. It's like having a flyby from space, dude! 
And btw, the image is under Creative Commons license? That's awesome for scientists and enthusiasts to use and share! 
. And a desktop wallpaper, yeah please! Can't wait to see what other sick pics Juno's gonna drop 
I mean, can you even imagine what it'd be like to see Jupiter up close? 
And the image they got of it is insane! I wish I could see it in person... or at least on my phone wallpaper 
and I'm still trying to wrap my head around it... 930 miles above the surface and they still managed to capture such breathtaking detail 
and I have to wonder what other secrets are hiding beneath those volcanic landscapes 
And can we talk about how cool it is that Emma Wälimäki got to process this image and make it look so gorgeous? Her work is truly a testament to human ingenuity. What I'd love to see next is some serious exploration of Io's surface, maybe with a lander or something. The scientific discoveries are endless, but exploring it up close would be, like, whoa 
Can't wait to learn more about the "Jupitershine" effect and what it reveals about Io's surface... maybe this is the key to understanding some of the mysteries of the moon's unique rotation 
. The fact that scientists are now analyzing data on Io to better understand its volcanic terrain makes me think we're just papering over our own problems with fancy technology 
.
The scientists are gonna have so much fun analyzing all these images and learning more about Io's volcanic surface 
It's amazing what tech can do, right? And the fact that they're making it available under a Creative Commons license for anyone to use? That's like, super cool 
. I'm loving how NASA is sharing this amazing image, btw - can't wait to see more space pics like this 
.
. I love how we're finally getting more info about this volcanic moon, it's like a whole new world revealed
