You’ve seen them. Those swirling, neon-purple nebulas and crisp, copper-colored Martian canyons that make you want to quit your job and buy a telescope. We’re currently living in a golden age of space and planets pictures. Between the James Webb Space Telescope (JWST) and the high-res cameras on the Perseverance rover, our feeds are basically a non-stop slideshow of cosmic eye candy. But here is the thing: if you were actually floating out there near the Pillars of Creation, you wouldn't see those vibrant magentas and electric blues. Not even close.
It’s kind of a shock to realize that most of the iconic images we obsess over are "false color." That sounds like a scam, doesn't it? It's not. It’s actually deep-bench data visualization.
The Reality Behind Those JWST Space and Planets Pictures
Most people think a space telescope is just a giant Nikon pointed at the sky. It isn't. The James Webb Space Telescope, for instance, looks at the universe in infrared. Human eyes are literally incapable of seeing that light. It’s invisible to us. So, when NASA releases a stunning new image of a distant galaxy, they have to translate that invisible infrared data into the visible spectrum—the rainbow we actually know (red, orange, yellow, green, blue, indigo, violet).
Think of it like a "translate" button on a foreign website. Astronomers assign colors to specific wavelengths of light. Usually, the longest wavelengths are assigned red, and the shortest are assigned blue. This isn't just to make it look "cool" for Instagram. It’s functional. By assigning these colors, scientists can tell exactly what gases are present. If you see a specific shade of teal in a nebula photo, that might represent oxygen. Red might be sulfur. Without this "artificial" coloring, the image would just be a black void or a grainy gray mess to our pathetic human retinas.
The Hubble vs. Webb Difference
It’s worth noting that Hubble sees mostly visible light, similar to how we see. This is why Hubble's space and planets pictures often look a bit more "natural," even if they are still processed. Webb goes deeper. It peers through dust clouds that Hubble can't penetrate. Because Webb is capturing heat signatures (infrared), it’s basically the ultimate night-vision goggles for the universe.
Why Mars Looks Different in Every Photo
Have you ever noticed that sometimes Mars looks like a bright, blood-red desert and other times it looks like a dusty, butterscotch-colored rock? That’s not a camera glitch.
When the Curiosity or Perseverance rovers take space and planets pictures on the surface, they use something called "white balancing." On Earth, we have a blue sky. This tints everything we see. On Mars, the sky is a hazy, dusty pinkish-red because of the iron-rich dust suspended in the thin atmosphere. If NASA sent back "raw" photos, everything would look weirdly orange-tinted, and it would be hard for geologists to identify the actual minerals in the rocks.

To fix this, they often adjust the color to "Earth-like" lighting. They basically pretend the sun is shining through an Earth atmosphere so they can say, "Okay, that rock is definitely basalt." It helps them compare Martian geology to what we find in places like Iceland or Hawaii. So, when you’re looking at these pictures, you’re often looking at a version of Mars that has been digitally "cleaned" to look like a desert in Arizona.
The Raw Data Is Actually Pretty Ugly
If you ever go to the raw data archives for the Juno mission—which is currently orbiting Jupiter—you’ll find images that look like blurry, monochromatic ghosts. It takes a village of "citizen scientists" to turn that data into the swirling, van Gogh-esque masterpieces we see on news sites.
NASA actually encourages this. They want you to download the raw files and process them yourself. People like Kevin Gill or Seán Doran have become legendary in the space community just for their ability to process JunoCam data. They use software like Photoshop and PixInsight to bring out the contrast in Jupiter's Great Red Spot.
- Fact Check: JunoCam wasn't even originally intended as a primary science instrument; it was put on the spacecraft mostly for public outreach.
- The raw files are stored as "rectified" frames that look distorted because of the spacecraft's spin.
- Color "enhancement" is used to show the vertical structure of clouds—the higher the cloud, the brighter it often appears.
Is It Still "Real" If It's Edited?
This is where the philosophy gets tricky. If I take a photo of you in a dark room and I use a flash, is that the "real" you? If I use night vision, is that "real"?

Space photography is about revealing information, not just capturing a "vibe." When we look at space and planets pictures of the Sun taken in X-ray or Ultraviolet light, we are seeing massive solar flares that are totally invisible to the naked eye. If we didn't "fake" the colors, we wouldn't know those flares existed, and our power grids would be a lot more vulnerable to solar storms.
Basically, the "true" color of space is mostly black. But the universe is screaming with information in frequencies we can't perceive. Photography is our way of listening to that scream.
The Problem with "Artist's Conceptions"
One thing that genuinely annoys me is when news outlets use an "artist's conception" and don't label it clearly. You've probably seen those hyper-realistic pictures of a planet with two suns or a black hole swallowing a star with a literal "drain" effect. Those aren't space and planets pictures. Those are paintings.
We didn't have a direct "picture" of a black hole until the Event Horizon Telescope (EHT) gave us that blurry, orange "donut" of M87* in 2019. Before that, every single image you saw of a black hole was an illustration. Even that 2019 image wasn't a "photo" in the traditional sense; it was a composite made from radio telescope data gathered from across the entire planet.
How to Tell the Difference Between Real and Fake
The internet is flooded with AI-generated space art now, which makes finding legitimate space and planets pictures harder. Real NASA or ESA (European Space Agency) photos have a specific "feel." They have noise. They have artifacts. They aren't perfectly smooth.

- Check the source. If it’s from
nasa.govoresa.int, it’s legitimate data, even if it’s color-enhanced. - Look for the "Star Spikes." On JWST images, bright stars have eight distinct diffraction spikes because of the hexagonal shape of the mirrors. Hubble has four. If a "photo" has random, pretty star glows, it’s likely a digital painting or AI.
- Shadows. Light in space is harsh. There is no air to scatter light, so shadows are pitch black and have very sharp edges. If you see soft, romantic lighting on a moon, someone probably made it in Blender.
Why We Should Care
We spend billions on these cameras for a reason. Understanding the composition of an exoplanet’s atmosphere—by looking at the "colors" of light passing through it—is how we’ll eventually find life. It’s not just about pretty wallpapers. It’s about chemical signatures.
When you look at a picture of Saturn’s rings and see those subtle beige and gray bands, you’re looking at the history of moons being ripped apart by gravity. You're looking at water ice contaminated by organic material. You're looking at physics in action.
Getting Started With Your Own Space Photography
You don't need a multi-billion dollar telescope to take your own space and planets pictures. Honestly, modern smartphones have "Night Mode" that can actually capture the Milky Way if you’re in a dark enough spot.
If you want to go deeper, you should look into "stacking." This is what the pros do. You take 50 photos of the same spot in the sky and use software (like DeepSkyStacker, which is free) to layer them on top of each other. This cancels out the "noise" and makes the faint light of a nebula pop. It’s exactly what the big telescopes do, just on a much smaller scale.
Next Steps for the Aspiring Cosmic Observer:
- Download the Raw Files: Go to the JunoCam website and try your hand at processing a raw image of Jupiter. It’s harder than it looks but incredibly rewarding.
- Identify the Spikes: Open the famous JWST "Deep Field" image and count the spikes on the brightest stars. Notice how the galaxies in the background are stretched and warped—that’s gravitational lensing, a real-world ripple in space-time.
- Check the Metadata: Whenever you see a viral space photo on social media, search for it on the official NASA Image and Video Library. If it’s not there, treat it with skepticism.
- Get a "Dark Sky" App: Find a location near you with low light pollution. Even a cheap pair of 10x50 binoculars will show you that Jupiter isn't just a dot—it's a disc with four tiny pinpricks of light (the Galilean moons) sitting right next to it.
The universe isn't trying to hide its beauty, but it doesn't speak our visual language. Every time you see one of these incredible space and planets pictures, remember that you’re looking at a translation. It's a bridge between the invisible reality of the cosmos and the limited, three-color vision of the human eye. Enjoy the view, but always remember to look for the data behind the glow.
