NASA's Juno spacecraft captured breathtaking images of Jupiter's volcanic moon Io during its close flyby on December 30, 2023. The stunning visuals, taken from about 930 miles above the surface, offer a unique glimpse into Io's night side, illuminated by "Jupitershine" - sunlight reflected off Jupiter's own planet.
The resulting image is not only visually striking but also provides valuable insights into the complex geological processes that shape Io's surface. The NASA Science Image of the Month for October 2025, this photo has been chosen to showcase Io's dynamic and ever-changing landscape, featuring some of the most extreme volcanic activity in our solar system.
The JunoCam instrument on board the spacecraft successfully captured this incredible image, which highlights the moon's rugged terrain and intense volcanic features. By studying images like these, scientists can gain a deeper understanding of Io's unique environment and the processes that drive its volcanic activity.
Io's surface is one of the most extreme in our solar system, with hundreds of volcanoes and geysers spewing forth molten lava and ash. The latest images from NASA's Juno spacecraft offer a thrilling glimpse into this unforgiving world, providing scientists with a wealth of data to analyze and understand the moon's complex geological history.
As part of its mission to explore Jupiter's moons, NASA's Juno spacecraft has been capturing stunning images of Io since 2013. These photographs showcase the incredible diversity of the moon's surface, from volcanic plumes to lava flows, and have provided scientists with a unique window into Io's internal dynamics.

I'm loving these new pics of Io from Juno, but can anyone tell me what exactly is this "Jupitershine" thing? Is it just sunlight reflected off Jupiter or is there some science behind it that I'm missing? 
Also, how far away were the cameras when they took these pics? 930 miles seems like a pretty small distance. Does that mean we're getting an up-close view of Io's surface without actually being there? 
. I mean, who needs that much molten lava and ash in our solar system? It's like, what's the point of having a moon with that many geysers? It's just gonna make Io look all ugly and harsh. And those images from Juno are just showing us how extreme and barren it is... doesn't exactly scream 'beautiful' to me 
. I'd rather see some more colorful moons or something.
I'm still trying to wrap my head around these insane images of Io! Like, can you believe we're seeing sunlight reflected off Jupiter's own planet? It's mind-blowing! And the fact that NASA's Juno spacecraft is giving us a glimpse into this volcanic moon's surface is just incredible. 
I mean, hundreds of volcanoes and geysers spewing forth molten lava and ash? That's some next-level stuff right there! 
It's amazing how scientists can learn so much from these images and gain insights into Io's unique environment. Can't wait to see what other cool pics Juno comes up with! 
just saw the pics from Juno's flyby of Jupiter's moon Io and I'm MIND BLOWN 
it's like a never-ending sci-fi movie over there. And the fact that scientists can study these images to learn more about Io's geology is just amazing 
. I mean, who needs space travel when you have NASA's Juno spacecraft? 
io is like soooo extreme lol i mean we're talkin 300+ volcanoes & geysers... that's crazy! and can u believe the junocam instrument captured all these gorgeous pics? i'm low-key obsessed with space now 
! I mean, who needs a beach vacation when you can explore a volcanic moon with lava flows and geysers? 
The pics from Juno are straight fire 
. It's like, our solar system has its own natural wonders 
. Can't wait to see more pics from NASA's Juno spacecraft 
it's crazy to think about how much data they've been collecting since 2013 and still we don't know everything about io 
, can you believe that NASA's Juno spacecraft just captured images of Jupiter's volcanic moon Io? The visuals are insane 
. And I mean, 930 miles above the surface? That's crazy close! 
The fact that they're able to capture such high-quality images of Io is just wow...
️. the way the jupiter shine is illuminating the whole surface, highlighting these massive volcanic features... it's mind-blowing 
! they can study this stuff for years and come up with even more insights about io's geology and history 
. we're really lucky to be living in a time where space exploration is making such awesome discoveries 
, with all those volcanoes and geysers erupting everywhere. And the JunoCam instrument is like a superhero, capturing all these amazing pics
