For decades, we’ve been staring at the same old face. The "Man in the Moon" with its dark, basaltic plains and familiar craters. But there’s a whole other half of that giant rock in the sky that remains a total mystery to the average person. Most people call it the "Dark Side," which, honestly, is a bit of a misnomer. It gets just as much sunlight as the side we see. It’s just that it’s locked away, forever facing the deep, cold void of space because of a gravitational quirk called tidal locking.
If you’re wondering what does the back of the moon look like, prepare to be a little disappointed if you were hoping for alien bases or secret Nazi outposts. It’s actually much more rugged, battered, and—strangely enough—lighter in color than the side we know. It looks like a completely different world.
The Great Lunar Asymmetry
Basically, the Moon is a two-faced celestial body. When the Soviet Luna 3 probe snapped the first grainy photos of the far side in 1959, scientists were genuinely baffled. They expected it to look like a mirror image of the near side. It wasn't. Not even close.
The near side is defined by these massive, dark patches called maria. These are essentially ancient solidified lava seas. Early astronomers thought they were actual oceans of water. On the back of the Moon, these maria are almost entirely missing. Instead, it’s a chaotic, densely packed graveyard of craters. It’s "highlands" all the way down.
Why the difference? This is one of the biggest debates in lunar science. Some researchers, like those at Penn State, suggest it’s because of how the Moon cooled. When the Moon was first formed from a massive impact with Earth, it was incredibly hot. Earth was also a molten ball of radiation. Because the Moon was already tidally locked, the near side was constantly baked by the Earth’s heat. The far side, facing away, cooled much faster. This allowed a thicker crust to form on the back. When asteroids hit the near side, they punched through the thin crust and let lava bleed out, creating those dark seas. On the back? The crust was too thick. The asteroids just left dents.
A Landscape of Infinite Craters
If you stood on the back of the moon, you’d notice immediately that the horizon feels more jagged. There are no vast, flat plains to walk across. You are surrounded by a relentless terrain of impact sites piled on top of impact sites.

One of the most mind-blowing features is the South Pole-Aitken Basin. It’s one of the largest, deepest, and oldest known impact craters in the entire solar system. It’s about 2,500 kilometers (1,550 miles) wide. If you put it on Earth, it would stretch from London to Athens. Because it’s so deep, it might actually expose the Moon's mantle. This is why China’s Chang’e 4 mission—the first to actually land on the far side—chose a spot within this basin back in 2019. They wanted to see what the "guts" of the Moon were made of.
The Color Palette of the Far Side
While the near side has those distinctive "black" spots against a grey background, the back of the Moon is a much more uniform, pale grey. It's almost blindingly bright in some areas. Without the dark basaltic flows to break up the scenery, the landscape is dominated by anorthosite, a type of rock that’s rich in feldspar. It reflects sunlight differently.
It feels more "pristine" in a violent sort of way. Since there hasn't been much volcanic activity to "resurface" the back, it’s a perfect record of the early solar system’s history. It’s like a scarred shield that’s been taking hits for 4 billion years to protect... well, not necessarily to protect Earth, but it’s certainly been in the line of fire.
Silence and the "Radio Shadow"
What does the back of the moon look like in terms of atmosphere? Still none. But it sounds like nothing. Literally.
One of the coolest things about the far side isn't what you see, but what you don't hear. The bulk of the Moon acts as a massive physical shield against all the radio noise coming from Earth. Our planet is incredibly loud. We leak radio waves, television signals, and cellular data into space constantly. For radio astronomers, this is "light pollution" for the ears.

The back of the Moon is the quietest place in the nearby solar system. It’s the only place where we could potentially build a radio telescope to listen to the very first signals from the Big Bang without Earth's chatter getting in the way. This "radio shadow" makes it the most valuable piece of real estate for deep-space observation.
Missions That Changed the View
We didn't just guess what was back there. We’ve been peeking over the shoulder of the Moon for decades.
- Luna 3 (1959): The USSR got there first. The photos were terrible by today’s standards—fuzzy, noisy, and developed on the spacecraft itself—but they changed everything.
- Apollo 8 (1968): This was the first time human eyes actually saw the back of the Moon. Frank Borman, Jim Lovell, and Bill Anders orbited the Moon and described it as a "whitish grey, like dirty beach sand."
- Lunar Reconnaissance Orbiter (LRO): Since 2009, NASA’s LRO has been mapping the surface in insane detail. We now have 3D maps of the far side that are more detailed than maps of our own ocean floor.
- Chang’e 4 (2019): China’s lander and its rover, Yutu-2, are still roaming around back there. They had to launch a special relay satellite, Queqiao, just to talk to the rover because—remember—the Moon blocks all direct signals to Earth.
Misconceptions You Should Toss Out
Let's clear some things up. The "Dark Side of the Moon" is a Pink Floyd album, not a scientific reality.
During a New Moon (when the side facing us is dark), the far side is actually in full, glorious sunlight. It goes through the exact same phases we see, just on the opposite schedule.

Also, it's not a smooth "shield." Some people think the far side is more cratered because it "protects" Earth from asteroids. That's actually a bit of a myth. Earth is a much bigger gravitational target. The reason the far side looks more battered is simply because the lava flows on the near side covered up all the old craters. The near side used to look just as messy, but it got a "fresh coat of paint" from volcanic eruptions billions of years ago.
Why We Are Going Back
The back of the moon is the next frontier for "lunar resource" mining. Because it’s so heavily cratered, there are spots at the poles that are in permanent shadow. These "cold traps" are where we find water ice.
Water isn't just for drinking. If you can crack water (H2O), you get hydrogen and oxygen. That’s rocket fuel. The back of the Moon could essentially become the first "gas station" for missions to Mars.
Actionable Insights: How to "See" the Back of the Moon Yourself
You can't see the far side with a backyard telescope. It’s physically impossible from the surface of Earth. However, you can explore it better than most astronauts could forty years ago.
- Use the LRO Quickmap: NASA has a free, web-based tool called Quickmap. You can toggle the view to the Far Side and zoom in until you can see individual boulders. It’s addictive.
- Download NASA’s "Moon Trek": This is a browser-based portal that lets you fly over the far side in 3D. You can even generate files to 3D print your own model of the Aitken Basin.
- Check the Chang’e 4 Image Releases: The China National Space Administration (CNSA) periodically releases high-res panoramas from the surface. The lighting is weirdly yellow-ish because of the mineral composition of the soil there.
- Wait for Artemis: NASA’s Artemis program intends to put humans back on the Moon, with potential missions targeting the South Pole, right on the edge of the far side.
The back of the moon is a harsh, jagged, and lonely place. It lacks the romantic "seas" of the side we grew up with. But in its silence and its scars, it holds the blueprint of how our little corner of the universe was built. If you want to understand where we came from, you have to look at the side that never looks back at us.
Keep an eye on the news regarding "Radio Quiet Zones" on the Moon. International treaties are currently being debated to ensure that as we start colonizing, we don't ruin the radio silence of the far side with satellites and Wi-Fi. Protecting that silence is just as important as protecting the physical landscape.
