Cataloging NEOs Down to 140 Meters: NASA and ESA’s New Planetary Defense Mission
Not long ago, the idea of defending Earth from an asteroid sounded like pure science fiction. It was something you’d expect from a Hollywood disaster movie, not a space agency budget proposal. But today, protecting our planet from near-Earth objects (NEOs) has become a serious, well-funded scientific priority. NASA and the European Space Agency (ESA) have now set a bold shared goal: to detect and catalog at least 90% of all NEOs that are 140 meters or larger. Simply put, they want to find nearly every space rock big enough to erase a major city from the map.

How Sunlight Spins Space Rocks: New Insights into the YORP Effect
For decades, astronomers believed that the spins of asteroids were shaped almost entirely by violent collisions and gravitational encounters. That story is now changing. As telescopes grow sharper and space missions more precise, scientists are uncovering the surprising truth: sunlight itself can gradually twist, tilt, and even tear apart asteroids. This subtle, long-term influence is known as the YORP effect, and it is rapidly becoming one of the most intriguing topics in planetary science.

BioSuit: The Next-Generation Space Suit That Fits Like a Second Skin
When we picture an astronaut, most of us imagine a bulky white suit — stiff, heavy, and inflated like a balloon. It’s an icon of space exploration, but also a symbol of how difficult it is to move freely in the vacuum of space. For decades, astronauts have battled against the rigidity of their suits just to bend an arm or take a step.

The Hidden Magnetism of Space: Why Objects That Don’t Attract on Earth Pull Together Among the Stars
If you drop a pen and a paperclip on your desk, they just sit there. Nothing happens — no invisible force draws them together. But take those same two objects far away from Earth, into the silent vacuum of space, and something extraordinary begins to happen: they start to move toward each other. Slowly, almost imperceptibly at first, but undeniably. It sounds like science fiction — yet it’s a real and fascinating truth about how the universe works.

Pandora Mission: Opening a Cosmic Box of Secrets
For centuries, humanity has looked to the night sky in wonder — to predict the seasons, to navigate oceans, or to seek meaning among the stars. Today, our gaze has a new purpose: to find out whether we’re alone in the universe. And leading this quest is NASA’s Pandora mission, a small but mighty space telescope designed to study the atmospheres of 39 distant exoplanets — all while watching their host stars and planets simultaneously.

SPHEREx: The Space Telescope That Will Redraw Our Map of the Universe
When we gaze up at the night sky, we see a silent ocean of stars — calm, timeless, and still. But behind that peaceful illusion lies a dynamic history: galaxies forming, stars igniting, and cosmic structures evolving over billions of years. To truly understand where we came from, astronomers must look back — far back — into the cosmic dawn. And soon, a new explorer will help them do just that.

Enceladus: The Moon That Sprays Secrets of Life Into Space
When astronomers first discovered Enceladus, one of Saturn’s many icy moons, few suspected it would become one of the most exciting places in the solar system. Barely 500 kilometers across, this tiny world seemed frozen, silent, and geologically dead. But in 2005, NASA’s Cassini spacecraft made a discovery that shocked scientists — Enceladus wasn’t dead at all. It was alive with activity, shooting enormous plumes of water vapor and ice particles far into space.

The New Frontier of Worlds: Super-Earths, Mini-Neptunes, and Ocean Planets
When astronomers first discovered planets orbiting other stars—so-called exoplanets—they expected to find worlds similar to those in our own Solar System: rocky like Earth, or massive and gaseous like Jupiter. What they actually found was far more surprising. The galaxy, it turns out, is filled with planets that defy our expectations—entirely new types of worlds that blur the line between the familiar and the fantastical.

The Hungry Orphan of the Cosmos: A Young Rogue Planet Devours Dust and Gas in Deep Space
In a quiet corner of the southern sky, hidden within the faint glow of the Chamaeleon constellation, a young, lonely world is rewriting the rules of planetary birth. The object, known as Cha 1107-7626, is what astronomers call a rogue planet — a planetary-mass body that drifts freely through space without orbiting a star.

The “Planet Y” Hypothesis: A Hidden World at the Edge of Our Solar System
For decades, astronomers have known that the Solar System doesn’t end with Neptune. Beyond it stretches the Kuiper Belt — a vast, icy frontier filled with dwarf planets, comets, and frozen remnants from the early days of planetary formation. Yet, recent discoveries suggest that something strange is happening out there.

Augmented Reality in Space Training: How AR Is Redefining the Way Astronauts Learn
For decades, astronaut training has been a blend of cutting-edge science, engineering precision, and pure human endurance. From massive simulators to underwater training tanks mimicking zero gravity, preparing for spaceflight has always required an intense and costly mix of physical and mental conditioning.

Everyday Life Aboard the International Space Station: Ordinary Days in an Extraordinary Place
When most people think about the International Space Station (ISS), they picture astronauts floating in a silent, endless void — surrounded by high-tech panels and dazzling views of Earth. But beyond the science fiction image, the ISS is also something much more relatable: a home. For the astronauts who live there, orbiting 400 kilometers above our planet, daily life is surprisingly familiar — and yet utterly unlike anything on Earth.
