How Planetary Defense Works: The Modern Methods Behind Tracking Asteroids
When we look up at the night sky, it often appears calm, steady, and predictable. But beyond that serene view lies a dynamic neighborhood of drifting rocks, icy remnants, and fast-moving objects. Among them are asteroids—cosmic leftovers from the early Solar System that occasionally wander a little too close to Earth.

59 Missions to Mars: Why Only Half Have Succeeded and What It Means for Humanity
Mars has long been humanity’s ultimate frontier. The Red Planet has captured our imagination for decades, promising answers to questions about the origins of life, the history of our solar system, and even the future of humanity itself. Yet despite decades of effort, reaching Mars has proven to be far more difficult than many expected.

Salyut-1: The First Space Station That Changed Humanity’s Future
In April 1971, humanity crossed a threshold it had only imagined for decades. A massive cylindrical structure, covered in panels and antennas, rose into the sky atop a roaring launch vehicle. This structure—later known to the world as Salyut-1—became the first human-made space station ever placed into orbit. Until that moment, astronauts and cosmonauts could only leap into space briefly before quickly returning home. Salyut-1 changed everything. For the first time in history, humans could live and work in space for weeks at a time.

Cosmic Spin Masters: The Stars That Rotate So Fast They Flatten Themselves
When most of us picture a star, we imagine a flawless glowing sphere—something smooth, round, and uniform. But the universe, as usual, loves to surprise us. Some stars defy this classic picture entirely. They spin so rapidly that their shape becomes distorted, stretched, and dramatically flattened. These celestial whirlers are some of the most intriguing objects astronomers have ever observed, and they challenge our understanding of what a star can be.

Cosmic Bridges: The Hidden Gravitational Highways Linking Galaxies
When we look up at the night sky, galaxies appear as isolated islands scattered through an endless, silent ocean. But modern astrophysics paints a very different picture. Rather than drifting alone, galaxies are woven into a vast interconnected structure held together by invisible forces. This structure is threaded with what scientists sometimes call “cosmic bridges” — gravitational channels that link galaxies across unimaginable distances.

The Giant Accretion Rings of Black Holes: Cosmic Structures Thousands of Light-Years Across
When most people picture a black hole, they imagine a dark, compact monster devouring anything that strays too close. That image isn’t wrong, but it’s also far from complete. Modern astronomy has revealed that some black holes aren’t just surrounded by small disks of hot gas—they are embedded within enormous cosmic structures called accretion rings, stretching across thousands of light-years. These colossal rings challenge our understanding of how galaxies evolve, how black holes feed, and how matter behaves under extreme gravitational forces.

If the Sun Turned Into a Black Hole, Earth Would Still Orbit It — Here’s the Mind-Bending Reason Why
When most people hear the words “black hole”, they imagine a cosmic monster: a gravitational vacuum cleaner devouring everything in its path. So at first glance, the idea that Earth could calmly keep orbiting the Sun if it suddenly collapsed into a black hole sounds impossible — almost like a trick question from an astronomy class.

Runaway Stars: The Cosmic Sprinters Racing Out of the Milky Way at 2,000 km/s
When we look up at the night sky, the stars seem eternal and unmoving. We imagine them as quiet beacons, frozen in place. But in reality, every one of them is hurtling through space at incredible speeds. Most stars drift along at a calm and predictable pace—maybe a few dozen or a few hundred kilometers per second. Fast by human standards, but nothing extraordinary by galactic ones.

Are There “Cosmic Spheres” of Antimatter?
Possible Relics of Ancient Universal Processes Antimatter is one of the most fascinating substances in the universe. It flashes into existence in violent cosmic events, vanishes the moment it touches ordinary matter, and leaves behind nothing but pure energy. Scientists chase its traces using the world’s most sensitive instruments. But a bold idea has been circulating in astrophysics: what if the universe still hides large objects made of antimatter—stable structures formed in the earliest moments after the Big Bang?

The Space Garden on the ISS: How Astronauts Grow Lettuce and Microgreens in Orbit
When most people imagine life aboard the International Space Station (ISS), they picture floating astronauts, futuristic experiments, and breathtaking views of Earth rising over the curve of the planet. What they don’t usually picture is a garden. Yet hundreds of miles above us, orbiting at nearly 28,000 kilometers per hour, astronauts tend to a small but remarkable “space greenhouse” where they grow fresh lettuce and nutrient-packed microgreens.

Japan’s Wooden Satellites: How Engineers Are Reinventing Space Technology With Timber
When you picture a satellite orbiting Earth, you probably imagine something metallic and high-tech—aluminum panels, titanium frames, maybe a few carbon-fiber components. The very last material you’d expect to see floating 400 kilometers above Earth is… wood.

Worlds With Three Suns: The Strange and Stunning Reality of Triple-Star Planets
Most of us grow up imagining a solar system as something simple and orderly: a single star with a neat family of planets circling around it. Our own Sun reinforces that picture. But the universe rarely sticks to simple patterns. Among the billions of stars in the Milky Way, there exist far more complex arrangements — including triple-star systems. And what’s even more astonishing is that some of these systems are home to planets that orbit all three stars at once.
