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.

Astronomy and Philosophy: How the Cosmos Transforms Our Thinking
When we lift our eyes to the night sky, gazing at stars, planets, and the vast darkness beyond, we encounter not only the physical expanse of the universe but also the boundless depths of our own consciousness. Astronomy and philosophy are two ancient ways of understanding the world, and together they create a unique lens that can profoundly shift human thought. But how exactly does the cosmos influence our perception, values, and sense of self?

How Galaxy Models Are Created: Peering into the Structure of the Universe
Modeling galaxies is one of the most fascinating and complex areas of modern astrophysics. These enormous islands of stars, stretching across hundreds of thousands of light-years, hold countless mysteries about the origins and evolution of the cosmos. To unlock these secrets, scientists build sophisticated mathematical and computer models that do far more than create pretty pictures — they allow us to understand how the universe formed its first structures after the Big Bang and to predict what will happen to galaxies billions of years from now.

The Solar Corona: The Mysterious Fiery Crown of the Sun
The solar corona is the Sun’s outermost atmospheric layer — its most rarefied and hottest part. Although barely visible from Earth except during a total solar eclipse, the corona holds countless mysteries that scientists have been striving to unravel for decades. What makes it so unique, and why is studying it essential not only to understanding the Sun but also to predicting the space weather that impacts our planet?

What Is the Exosphere and Why Is It Important?
When we look up at the night sky, it often feels as if space begins just beyond the clouds. However, the boundary between Earth’s atmosphere and outer space is far more complex and mysterious than it seems. The exosphere — the outermost layer of Earth’s atmosphere — stretches far into space and plays surprisingly important roles that affect not only our planet but also humanity’s ventures beyond. Let’s explore what the exosphere really is, what it’s made of, and why it matters so much.

How the Tiangong Space Station Works: China’s Orbital Harbor of the Future
China’s Tiangong space station is one of the most ambitious projects in modern space exploration, marking a confident leap toward autonomous presence in Earth’s orbit. The name “Tiangong” (天宫) translates to “Heavenly Palace,” and though it’s not made of gold or jade, it is a palace of cutting-edge technology, aluminum, and solar panels orbiting high above us. This station is the third long-term orbital laboratory in human history after the International Space Station (ISS) and Russia’s Mir, and notably, the first to be built solely by one country in the 21st century.

The First Evidence of Extraterrestrial Life: Are We Alone No More?
For as long as humans have gazed up at the stars, we've asked a profound question: Are we alone in the universe? While the idea of life beyond Earth has long been the stuff of dreams, philosophy, and science fiction, it’s only recently that we’ve begun to gather actual scientific evidence—however tentative—that might suggest we're not the sole inhabitants of the cosmos.

Why Do Stars Twinkle? The Science Behind the Sparkle
Have you ever looked up at the night sky and noticed how stars seem to flicker, shimmer, or dance? Some twinkle gently, while others seem to blink rapidly as if playing a cosmic game of hide-and-seek. This beautiful celestial effect has inspired poets, dreamers, and scientists for centuries. But what really causes stars to twinkle?

What Is Cosmic Time and How Do We Measure It?
When we think about time, we often imagine it ticking away steadily, second by second, just like the clocks on our walls or the calendars we flip through each year. On Earth, time feels predictable and constant. But in space, time behaves in strange and fascinating ways. The deeper we explore the cosmos, the more we realize that time in space—often called cosmic time—is anything but ordinary.
