Speculation, theory, UFOs and Aliens. Are we alone in this universe or is there life outside Earth?
What Really Happens During a Spacewalk: A Step Beyond the Edge of Earth
Floating above the Earth, with nothing but the stars ahead and the planet far below, astronauts stepping out of their spacecraft enter one of the most extreme and awe-inspiring environments imaginable — open space. Known officially as an EVA, or extravehicular activity, a spacewalk is a breathtaking feat of human engineering and courage. But what actually happens when someone leaves the safety of a spaceship and ventures into the cosmic void?

Why the Universe Doesn’t Fall Apart: The Forces Holding the Cosmos Together
The universe is vast, dynamic, and constantly expanding. It contains incomprehensible forces, staggering distances, and matter unevenly scattered across the cosmic landscape. So why doesn’t it all simply collapse or drift apart into chaos? The answer lies in the intricate balance of physical laws, the invisible forces of gravity, and the surprising roles played by dark matter and dark energy. These elements work together in a delicate harmony, holding the universe in a complex but stable structure.

How Time Works in Space: From Relativity to the Rhythm of the Universe
Time may seem like one of the most straightforward aspects of life—constantly ticking forward, evenly and reliably. On Earth, we mark it with clocks and calendars, confident that a second here is a second anywhere. But when we look beyond our planet into the vastness of space, time transforms into something far more mysterious. In the cosmos, time is flexible, curved, and deeply dependent on gravity, speed, and the very shape of space itself. Understanding how time works in the universe requires us to go beyond our everyday experience and dive into the strange and beautiful laws that govern reality.

How the Planets Got Their Names: A Journey Through Mythology, History, and Astronomy
When we hear names like Mars, Jupiter, or Venus, we rarely pause to ask where those names come from. Yet behind each planetary name lies a rich tapestry of mythology, history, and human curiosity. The story of how planets were named isn't just a list of pretty words—it’s a reflection of our ancestors’ attempts to make sense of the universe, to give form to the unknown, and to project meaning onto the glowing lights in the sky.

Why Is the Night Sky Dark? The Olbers’ Paradox Explained
When you look up at the night sky, it’s easy to be overwhelmed by its vastness and quiet beauty. Tiny stars twinkle against an ocean of blackness, stretching endlessly in all directions. But have you ever truly wondered — why is the night sky dark at all? It seems like a simple question, yet it puzzled scientists for centuries and sparked one of the most fascinating paradoxes in astronomy: Olbers’ Paradox.

Solar Cycles and Their Impact on Planets: The Invisible Hand of Our Star
The Sun is far more than a glowing ball of plasma lighting up our skies. It’s a living, dynamic star, constantly shifting and evolving. One of the most fascinating manifestations of its activity is the solar cycle—a recurring pattern in which the Sun’s magnetic field changes direction approximately every 11 years. These cycles bring with them fluctuations in sunspot numbers, powerful flares, and massive eruptions of solar material. But how exactly do these solar rhythms affect not just Earth, but other planets in our solar system as well?

Exploring the Cosmic Vacuum: The Mysteries of Absolute Emptiness
When we think about space, images of dazzling stars, swirling galaxies, massive planets, and enigmatic black holes typically come to mind. But beyond these celestial wonders stretches something far more mysterious — the cosmic vacuum. At first glance, it might seem like a vast and silent void, completely empty of matter, air, and sound. But in truth, the vacuum of space is far from simple. Modern research reveals that this “nothingness” plays a fundamental role in the structure and evolution of the universe.

The Golden Age of Space Exploration: Are We Living in It Now?
In recent years, one phrase has been appearing more and more in scientific articles, media headlines, and space documentaries: “the golden age of space exploration.” But what exactly does this mean? And why do so many experts believe that we are living through one of the most thrilling and fast-paced chapters in the history of humanity's journey to the stars?

How Space Affects Human DNA: Genetics in Microgravity
Space is not just a silent, star-filled void. It’s a harsh, alien environment that pushes the human body to its limits. In space, gravity is almost nonexistent, radiation levels are dangerously high, and our internal biological rhythms become disoriented. Among the many fascinating challenges posed by space travel, one of the most intriguing is how space affects human DNA — the blueprint of life.

Weighing the Giants: How Scientists Measure the Mass of Galaxies
The universe is filled with billions of galaxies—vast cosmic cities made of stars, gas, dust, and, as we now know, dark matter. These galactic structures come in all sizes, from tiny dwarf galaxies like the Small Magellanic Cloud to colossal giants like the elliptical galaxy IC 1101, which contains trillions of stars. But how can scientists possibly measure the "weight" of something so enormous and distant—millions or even billions of light-years away? It’s not like you can put a galaxy on a scale. The answer lies in the clever methods of astrophysics—a science that often borders on detective work.

The History of Early Satellite Development: From Dreams to Orbit
When humanity first dared to dream of conquering space, the concept of a satellite seemed like something out of a science fiction novel. And for a while, that’s exactly what it was—an idea far beyond the reach of existing technology. But by the mid-20th century, that dream began transforming into reality. The story of the first satellites is not just a tale of engineering brilliance—it’s a dramatic narrative of global rivalry, scientific revolution, and an astonishing leap forward in human progress.
