Something unusual has been spotted on the moon and it’s getting attention for a reason. New high-resolution observations linked to NASA’s Artemis program revealed areas where the lunar surface appears to have shifted, cracked, or partially collapsed. In some images, it even looks like a section of the moon has broken away. At first glance, this sounds extreme. The moon is usually described as geologically inactive, a stable and unchanging world. But the data tells a different story. Certain regions now show surface features that were not clearly visible in older imagery, suggesting relatively recent changes. The key to understanding this lies in how the moon actually evolves. Even without plate tectonics like Earth, the moon is still slowly changing. One of the main reasons is temperature. The lunar surface experiences extreme swings from about 120° C during the day to 130° C at night.
These rapid changes cause the surface material to expand and contract over and over again, gradually weakening rock structures. Over time, this leads to cracking. Another major factor is the moon’s internal cooling. As the moon slowly loses heat, its interior contracts. This process creates stress in the crust, forming features known as lobate scarps, which are essentially small cliffs or fault lines. Data from NASA’s Lunar Reconnaissance Orbiter has identified thousands of these structures, some stretching for several kilometers. What makes them important is their age. Many of these scarps appear relatively young, which suggests the The is still tectonically active on a small scale. There is also direct evidence of seismic activity. Instruments left on the surface during the Apollo missions recorded moonquakes with magnitudes up to about 5. 0. These are strong enough to shift surface material, especially in areas where the ground is already unstable.
Recent analysis shows that some of these lunar faults may have been active within the last 50 million years, which is extremely recent in geological terms. In some regions, boulders up to several meters in size have been observed at the base of cliffs, likely dislodged by seismic activity. Computer models suggest that even a moderate moonquake could trigger cascading rock falls across unstable slopes, especially near the lunar poles where future missions are planned. This means that what looks like a small surface crack in satellite images could actually be part of a much larger and ongoing structural shift. In several locations, high-resolution images show slopes that appear to have partially collapsed. Loose material has moved downhill, leaving behind fresh-looking surfaces that stand out from older terrain. In some cases, this creates the visual impression that a chunk of the moon has broken off.
In reality, these are most likely landslides or regolith movements triggered by moonquakes, temperature stress, or both. Micrometeorites add another layer to the process. The moon has no atmosphere, so even tiny particles strike the surface at high speeds. Over time, these constant impacts disturb the upper layer of dust and rock, making it easier for material to shift when other forces act on it. All of these factors combined make the lunar surface more dynamic than it appears from Earth. For scientists, this is not just an interesting detail. It has practical implications. Missions like Artemis are focused on long-term exploration, including future landings and potential infrastructure on the moon. Understanding which areas are stable and which are prone to change is critical. Regions with active fault lines or loose surface material could present risks for landing spacecraft or building equipment.
That is why updated mapping and continuous observation are so important. At the same time, these changes provide valuable scientific insight. They show that the moon is not completely inactive. It is still evolving, slowly reshaping its surface through small but continuous processes. The idea that a massive piece of the moon suddenly broke off is not supported by current evidence. But smaller-scale changes are happening. And they are measurable. And in some cases, they can look dramatic enough to raise new questions. Because when they look at the moon with higher precision than ever before, we are starting to see something unexpected. A world that seemed frozen in time is still changing. How about playing golf? Not on Earth, but on the moon. Let’s journey back to a time 50 years ago when one astronaut not turn the lunar surface into the most unusual golf course ever.
Any golfer will tell you how tricky it is to avoid sand traps, but picture Alan Shepard, a NASA astronaut dealing with an entire surface that feels like super fine powder. During the Apollo 14 mission, he took a break to showcase some spacey golf skills for everyone watching from Earth. After his first shot, he excitedly made another. For him, it seemed the ball went forever and ever. Fore! Let’s dial back to reality for a moment. Thanks to the research by the United States Golf Association, or USGA, we’ve got some numbers. They found that Alan’s first moon ball traveled 24 yd and his second stretched for 40 yd. Now, how does that compare to the average golf shots back here? In regular gravity, one usually swings to about 216 yd.
Just goes to show, while we’ve upgraded our golf game on Earth with tech and training, the moon’s low gravity playground is a different environment altogether. Now, let’s give Alan some props. Moon golf? Not as simple as you might think. His club wasn’t one from your local sports store. It was a makeshift one, a moon sample collector with a club head stuck to it. Add to that the bulky space Imagine trying to swing wearing an outfit that’s as stiff as cardboard. With all that gear, Alan could only muster a one-handed swing. Care to have a similar experience? Well, you might not be able to play golf on the moon anytime soon, but you can give it a shot underwater. Some say the conditions are similar. Here’s where it gets even more interesting. The USGA didn’t just take Alan’s word on where the balls landed.
They wanted to investigate. For starters, they used ultra-clear footage of the Apollo 14 mission. They also used some sharp images from NASA’s special moon camera launched in 2009. Using this imagery, they mapped out the journey of those two golf balls. Alan loved his unique golf club so much, he wanted to bring it back home. No big deal, right? Well, you see, in those days, astronauts would leave behind unnecessary items to make space for moon rocks, but not this club. So, during the ’70s, this interstellar golf club found a new home at the USGA museum in New Jersey. Unlike regular golf clubs, this one had a twist. It was crafted from aluminum and Teflon. It was built to fold and fit snugly within the tight spaces of the lunar lander. How did this whole moon golf idea even pop up?
Well, in 1970, golf legend Bob Hope paid a visit to NASA. Inspired by Hope’s love for golf, an idea came into Shepard’s head, moon golf. To turn his dream into reality, he collaborated with a golf professional and NASA’s tech specialist. Together, they crafted a club that met NASA’s strict safety norms. But hey, Alan didn’t want this to be just a surprise stunt. Remember, traveling to the moon required very strict protocols. They couldn’t just randomly have a picnic up there, you know? So, Alan made sure NASA officials agreed with this impromptu game of golf. They were initially skeptical, but eventually gave the green light after Alan passionately laid out his plan. He also promised he’d start playing if everything went smoothly on the mission. Determined to make it perfect, Alan prepped like a champ.
The story goes that he’d put on his hefty space suit and sneak off to secret spot so he could practice. Decades later, he’d still be reflecting on his lunar escapade. He was the only golfer to ever swing on the moon. It’s not just golf balls that astronauts left behind on their trips. There were actually a lot of objects left on the moon between 1969 and 1972, the year of the last moon landing. Each time you gaze up at the moon, remember that there’s a cute family photo up there, some huge science gadgets, a small statue, a bunch of, well, human waste bags, and yes, some American flags. Years have passed by, and yes, technically those items are still hanging out there, though they’ve probably seen better days because of the harsh conditions on the moon.
Some items had a special place in the astronauts’ hearts and were meant to stay on the moon. But hey, leaving some stuff behind also meant they could bring back moon samples. You know the feeling. It’s like when you need to make room in your suitcase for souvenirs when you’re finishing a vacation. Does NASA have a complete list of things they left on the moon? Well, not really. In fact, one team tried to create a record of some of the items and reached an amazing list of 106 left there from the Apollo 11 mission alone. And that’s not counting Neil Armstrong and Buzz Aldrin’s famous footprints. The largest items at each landing site were mostly the science-y stuff, like pieces of their lunar module and experiments to study the moon in depth.
Then there were some beautiful tokens, like Apollo 11’s plaque and a special disc with messages from leaders around the world. Some say the astronauts also took medals to remember some heroic cosmonauts, and they even left a gold olive branch, an age-old symbol of peace. Now, later moon missions had a little more fun, like Alan Shepard did with his golf game. But the award for the most heartwarming moment goes to Charlie Duke. During the Apollo 16 mission, he left a picture of his family up there. It’s like he wanted them to be a part of the adventure. Although, I heads-up, those photos probably didn’t age well because of the moon’s high exposure to the sun’s radiation. There might just be an art museum up there on our satellite, too. Let me explain. There’s this tiny little art piece called The Moon Museum.
It’s a ceramic chip about the size of your nail, and it was crafted by an artist named Forrest Myers. This tiny object showcases miniature artworks from six talented people. Among them are even the famous Andy Warhol, the same artist known for his iconic soup cans and celebrity portraits. Forrest Myers said he wanted his mini museum to be on the moon, but there was a problem. NASA officials weren’t exactly on board with the idea. However, Myers shared with the press that he handed over this art chip to an engineer working on the Apollo 12 mission. According to Myers, this engineer secretly tucked the Moon Museum onto a leg of the lunar lander. In case you haven’t figured it out yet, these lunar landers don’t come back to Earth after their mission. Take this with a grain of salt, though, as NASA has never confirmed this story.
You might wonder, why did they leave all these things? Sometimes it was about making a statement. Other times it was purely practical. At one point, it was mentioned that during the Apollo 11 mission, for example, a decision needed to be made. The astronauts had to quickly figure out what was essential for their trip back home. They ended up creating a cleanup spot, tossing away things they didn’t need anymore. Leaving things behind on the moon isn’t that different from how we leave things behind on Earth. Just like archaeologists study our ancient leftovers to learn about our ancestors, the stuff on the moon gives us insights about those incredible lunar missions. Some things they left had done their job, like the pole for the flag or the camera they used to broadcast those steps on the moon.
Even the tools astronauts used to collect samples were left because they had more precious cargo to bring back, moonrocks. When it comes to the current state of all these items, scientists are not entirely sure. We do know that NASA’s moon observer has spotted some of their shadows. They’re still up there. The official gear was built to resist, so it might behave a bit better. But those personal items, they’ve probably seen better days. There’s something happening inside the moon, something that nobody expected. Not a dramatic shift you’d see on the outside, but deep down where things seem frozen in time. Scientists have uncovered a hidden layer of what you could only call moon goo. Remember those school lessons about the crust, mantle, and core? Much like the Earth, the moon is made up of layers, a crust, mantle, and core.
However, the moon’s core is much smaller compared to ours. Earth’s core is huge. It makes up about a third of our entire planet’s mass. The moon’s core makes up only about 1 to 2% of its mass, and its diameter is about 1/5 the diameter of the moon itself. It’s surrounded by a hard rocky mantle. But it turns out that between these two layers, that mysterious goo layer, and it’s way more important than you might think. The layer is soft and partially molten, ebbing and flowing like the tides in our oceans. It rises and falls, stretching and shifting as if it were alive. Its movement isn’t chaotic, but subtle and regular. We always knew that the moon influences our seas and oceans, causing tides with its gravity. But it turns out that we influence it back.
The goo ocean reacts to the gravitational dance between Earth and the Sun. Also, the molten layer could be made of ilmenite, a very intriguing material. Ilmenite is rich in titanium, a strong and lightweight metal that we really love over here on Earth. Titanium is used in everything from airplane parts and spacecraft to medical devices, even in everyday items like bikes and laptops, all because it’s incredibly strong and very resistant to corrosion and heat. So, if the moon might have a molten layer rich in ilmenite, that would be awesome. Astronomers are already planning for lunar bases, and if we had a material to build structures, spacecraft, or even tools for astronauts right there, that would be a game-changer. Otherwise, we’d need to transport materials from Earth, which is extremely costly. This is our first tangible sign that the moon is not just a cold, boring rock.
Instead, it’s dynamic, living, and breathing with moving forces beneath the surface. NASA used new special tools to discover this, the Gravity Recovery and Interior Laboratory and the Lunar Reconnaissance Orbiter. These are both space missions designed to study the moon, but they don’t just look at the surface like a telescope. Instead, they help measure things we can’t see with our eyes, like the moon’s gravity and how it changes over time. GRAIL sent two small spacecraft around the moon named Ebb and Flow. Clever. The idea was for these spacecraft to fly close to each other and measure tiny differences in the moon’s gravity as they go. It’s like they were feeling the moon’s invisible pull in different places. If the moon’s gravity was stronger in one spot, the spacecraft moved closer together, and if it was weaker, they moved farther apart.
This helps scientists understand what’s going on inside the moon, even if they can’t actually go there. And the spacecraft intentionally crashed into the moon in December 2012 to end the mission. The Lunar Reconnaissance Orbiter is a bit different. It takes super detailed pictures of the moon and collects other important information about its surface. By combining the information from both GRAIL and LRO, we were able to find this goo layer. But, this discovery actually challenges everything we thought we knew about lunar geology. How did this molten layer get there? How long has it existed? And perhaps more fascinating, how it stayed warm for millions of years? That’s a million-dollar questions. The moon’s core generates heat just like ours. But, it’s not as easy as saying, “Oh, the core’s heat probably keeps it warm and molten.
” Well, first, the moon’s core is much smaller and less active than Earth’s, meaning it produces significantly less heat. Plus, the moon is much cooler than Earth in general. With temperature dropping to minus 200° F on the surface, how could this inner layer still stay in this flowing state? That’s still a mystery. In any case, this goo could actually explain a lot of stuff about the moon. For example, astronomers were exploring moonquakes and how they happen. Now, they think that it might be this semi-molten layer shifting and moving beneath the surface. Now, beyond the moon itself, it also tells us more about other celestial bodies. If the moon, something we considered basically a huge static rock, has such a dramatic life, what about other planets, moons, or asteroids? Could they also hide similar hidden movements beneath their surfaces?
We can even understand our own planet better, learn more about how tides and similar stuff works. There are so many great discoveries we’ve been making on the moon. Recently, we found some awesome stuff beneath the surface, massive caves hidden for millions of years. For over 50 years, scientists have suspected that the moon’s surface is full of underground tunnels and caves. These are known as lava tubes because they were formed by lava. Duh. Millions of years ago, the moon was pretty unstable. It underwent some volcanic activity causing eruptions. When a volcano erupts, lava can flow across the surface. As the outer layer of the lava cools and hardens, it forms a solid roof of dark material. It’s actually what these famous dark spots on the moon are. These are dark, hardened remains of ancient lava. But the hot molten lava continues to flow through the center.
Once the eruption ends and the lava drains away, what’s left behind is an empty hollow tunnel, hence a lava tube. On Earth, we have lava tubes in places like Hawaii or Iceland where volcanic activity has created similar underground tunnels. The same thing happened on the moon billions of years ago. Although they’re much crazier compared to ours. In fact, lunar lava tubes are now thought to be some of the largest and longest in the entire solar system. One such cave was discovered beneath the famous Mare Tranquillitatis, the place where Apollo 11 first landed. And it’s at least 340 ft deep. Now, all these lava systems have remained hidden just beneath the surface untouched for millions of years. Only now they finally managed to prove their existence. Scientists from the University of Trento in Italy found them using special radar technology and advanced computer methods.
These techniques let you see underground by sending radar waves. The waves bounce back and give clues about what’s hidden underneath. By analyzing the way these waves reflected back, the researchers could detect the shape and size of the hidden caves. Now, the best thing about this discovery is that we could build all our bases there. These caves protect from radiation, harsh winds, and meteoroids. NASA even found evidence that some of these caves stay at a steady 63° Fahrenheit. That’s some crazy coziness for the moon. And on top of that, there could even be some water there. So, humans could take shelter inside these natural tunnels and build entire colonies on the moon. And I know what you’re thinking. Could unexpected lunar monsters hide deep in those caves? Well, sure. There’s a huge potential for exploring these caves and finding some awesome stuff.
