A New Image of Black Hole Magnetic Fields Reveals a Stunning, Ultra-Detailed Structure
For decades, black holes have represented the ultimate frontier of observational astronomy: regions so extreme that even light cannot escape, where physics bends into unfamiliar shapes and our best theories are pushed to their absolute limits. Yet each year, astronomers take one step closer to transforming the unseeable into the observable. The latest achievement is nothing short of astonishing: scientists have produced the most detailed image ever made of the magnetic fields swirling around a supermassive black hole.

The First Evidence of “Pulsating” Emission from a Black Hole’s Accretion Disk
For decades, astronomers have observed mysterious flickers, flares, and quasi-periodic oscillations coming from black hole systems. These rhythmic bursts of radiation—especially in X-rays—have inspired hundreds of theories but offered few firm answers. Were they turbulence? Magnetic reconnection? Random instabilities? Or something deeper, tied to the very structure of spacetime near a black hole?

A New Idea Takes Shape: Dark Matter Might Be Superfluid — and Early Observations Are Starting to Hint at It
Every so often, astronomy produces a theory that feels almost too bold to take seriously at first glance. Yet these are precisely the ideas that sometimes transform our understanding of the Universe. One such proposal is now regaining momentum: dark matter, the mysterious substance shaping galaxies and cosmic structures, might not behave like a vast cloud of cold, inert particles after all. Instead, it could enter a superfluid state under the right conditions.

A New Candidate for a Dark-Matter-Free Galaxy — and Why It Challenges Modern Cosmology
For decades, dark matter has been treated as one of the fundamental building blocks of the Universe. According to the dominant ΛCDM (Lambda Cold Dark Matter) model, every galaxy—large or small—should be embedded in a massive halo of invisible, non-luminous matter. This dark halo is not a minor detail; it is a core element of the structure of the cosmos. It dictates how galaxies form, how they rotate, how they merge, and how their stars and clusters behave over billions of years.

A New World in the Shadows: Uranus Gains a Newly Discovered Moon, S/2025 U1
For decades, Uranus seemed like one of the quietest and least explored giants in our Solar System. Its pale-blue disk, distant and dim, concealed only a modest collection of known moons—until now. In 2025, astronomers announced a remarkable discovery: a previously unseen miniature satellite orbiting Uranus. The moon, currently designated S/2025 U1, is tiny, elusive, and scientifically promising. Despite its minuscule size—no more than 8 to 10 kilometers across—it adds an important new piece to the complex and dynamic architecture of Uranus’s moon system.

Euclid Has Found Hidden Giant Threads of the Cosmic Web — And They Are Challenging Our Models of the Universe
For decades, cosmologists have suspected that the Universe is woven together by an enormous and invisible scaffold: a vast network of filaments, bridges, knots, and voids known collectively as the cosmic web. This web is not a poetic metaphor. It is the real, physical structure of the cosmos on the largest scales—hundreds of millions of light-years across—shaped by dark matter, threaded by hot gas, and lit here and there by strings of galaxies.

Space Medicine Aboard the Station: How Astronauts Stay Healthy Beyond Earth
Life on an orbital space station is far more than breathtaking views and scientific breakthroughs. For astronauts, living in microgravity is a full-body experiment—one that never stops. Every minute spent in orbit reshapes the human body, changes how organs function, and challenges the limits of our biology. That’s why space medicine has become one of the most crucial, innovative, and fascinating branches of modern science.

Sports and Exercise in Space: How Astronauts Stay Fit Beyond Earth
When most people imagine life in space, they picture astronauts floating gracefully in a state of weightlessness, drifting between control panels while gazing at the blue glow of Earth through the station window. But behind these cinematic visuals lies a tough physical reality: the human body is not designed for life without gravity. Muscles shrink, bones weaken, and even the heart begins to lose strength.

The Crescent Planet: A World with a Permanent Terminator Line
Imagine a world where the sun never rises and never sets. A world where one hemisphere burns beneath an unmoving star while the other drowns in eternal night. Between them lies a narrow ring of twilight—an endless borderland where day and night touch but never mingle.

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.
