The Curiosity rover continues to capture fascinating anomalies on the Martian surface. In this instance, researcher Jean Ward has examined a particularly intriguing discovery: a disc-shaped object embedded in the side of a mound or hill.
The images were taken by the Curiosity rover’s Mast Camera (Mastcam) on April 30, 2025 (Sol 4526). To improve clarity, Ward meticulously removed the grid overlay from the photographs, enhancing the visibility of the object.
To provide better spatial context for the disc’s location, Ward assembled two of the images into a collage. In the composite, you can see the surrounding area including a ridge, and the small mound where the disc appears partially embedded, possibly near the entrance of an opening.
The next image offers the clearest view of the anomaly. Ward again removed the grid overlay and subtly enhanced the contrast to bring out finer details, as the original image appeared overly bright and washed out.
In the close-up, displayed at twice the original scale, the smooth arc of the disc is distinctly visible. Its texture seems unusual, resembling stone or a slab-like material, flat yet with a defined curvature.
Might this disc-like structure have been engineered as a gateway, part of a hidden entrance leading to an architectural complex embedded within the hillside, hinting at a long-forgotten subterranean stronghold once inhabited by an extraterrestrial civilization?

UVB-76, widely known by its nickname "The Buzzer," is a mysterious shortwave Russian radio station radio broadcasts in the world. It began broadcasting in the mid-1970s and is still active today, broadcasting cryptic signals at 4625 kHz.
This Russian shortwave station usual broadcast consists of a monotonous buzzing tone that occasionally breaks for cryptic voice messages in Russian. The station is widely believed to be operated by the Russian military, possibly as part of the Strategic Rocket Forces’ communication network.
The use of shortwave radio enables the signal to travel vast distances, potentially covering all of Russia and extending far beyond its borders.
Due to the high transmission power of UVB-76’s antenna, some theorize that the station’s signals could even reach outer space. This possibility opens the door to even more extraordinary speculation: that satellites might receive these signals and relay them to submarines, remote military units, or even unidentified aerial phenomena (UFOs). One theory even posits that UVB-76 could be part of an experimental system designed to scan or communicate with extraterrestrial life.
Under normal circumstances, UVB-76’s broadcasts are infrequent and minimal, just the repetitive buzz and the rare coded message. However, something highly unusual happened just ten hours ago. Within a single day, the station transmitted four coded voice messages, an event considered extremely rare and potentially significant.
These are the messages: NZHTI - 33 702 - NEPTUN - 66-52-20-75 NZHTI - 8002 361 - TIMUS - 56-85 NZHTI - 7000 0 8002 - LISOPLASH - 67-203-0808-0809 NZHTI - 62 505 - NUTOBAKS - 78 15 92 71
While the true meaning of these messages remains classified or unknown, some analysts believe they could be activation codes, operational signals, or test messages for military units. The repeated prefix "NZHTI" could be a call sign or an authentication marker. The names—NEPTUN, TIMUS, LISOPLASH, and NUTOBAKS, might refer to code-named operations, geographic regions, or military assets. The numeric sequences could represent coordinates, timestamps, or identification numbers.
Given the timing and unusual frequency of these messages, some suspect that UVB-76 is ramping up activity in preparation for a significant event. While there's no confirmation of any immediate threat, the sudden uptick in coded communications suggests that something serious could be developing.
Many experts believe UVB-76 is maintained as a wartime contingency channel, ready to relay commands in the event of nuclear war or a catastrophic loss of national communications. Its consistent presence, even during peacetime, supports the theory that it serves as an emergency or fail-safe communication method for defense forces.
The sudden surge of messages within one day suggests that something serious is happening, or about to. But who are they intended for? And more importantly, what comes next?" View the full article

Exploring the Universe Through Sight, Touch, and Sound
For the first time in history, we can explore the universe through a rich blend of senses—seeing, touching, and hearing astronomical data—in ways that deepen our understanding of space. While three-dimensional (3D) models are essential tools for scientific discovery and analysis, their potential extends far beyond the lab.
Space can often feel distant and abstract, like watching a cosmic show unfold on a screen light-years away. But thanks to remarkable advances in technology, software, and science, we can now transform telescope data into detailed 3D models of objects millions or even billions of miles away. These models aren’t based on imagination—they are built from real data, using measurements of motion, light, and structure to recreate celestial phenomena in three dimensions.
What’s more, we can bring these digital models into the physical world through 3D printing. Using innovations in additive manufacturing, data becomes something you can hold in your hands. This is particularly powerful for children, individuals who are blind or have low vision, and anyone with a passion for lifelong learning. Now, anyone can quite literally grasp a piece of the universe.
These models also provide a compelling way to explore concepts like scale. While a 3D print might be just four inches wide, the object it represents could be tens of millions of billions of times larger—some are so vast that a million Earths could fit inside them. Holding a scaled version of something so massive creates a bridge between human experience and cosmic reality.
In addition to visualizing and physically interacting with the data, we can also listen to it. Through a process called sonification, telescope data is translated into sound, making information accessible and engaging in a whole new way. Just like translating a language, sonification conveys the essence of astronomical data through audio, allowing people to “hear” the universe.
To bring these powerful experiences to communities across the country, NASA’s Universe of Learning, in collaboration with the Library of Congress, NASA’s Chandra X-ray Observatory, and the Space Telescope Science Institute, has created Mini Stars 3D Kits that explore key stages of stellar evolution. These kits have been distributed to Library of Congress state hubs across the United States to engage local learners through hands-on and multisensory discovery.
Each Mini Stars Kit includes:
Three 3D-printed models of objects within our own Milky Way galaxy: Pillars of Creation (M16/Eagle Nebula) – a stellar nursery where new stars are born Eta Carinae – a massive, unstable star system approaching the end of its life Crab Nebula – the aftermath of a supernova, featuring a dense neutron star at its core Audio files with data sonifications for each object—mathematical translations of telescope data into sound Descriptive text to guide users through each model’s scientific significance and sensory interpretation These kits empower people of all ages and abilities to explore the cosmos through touch and sound—turning scientific data into a deeply human experience.
