astronomy
Celestial objects and the phenomena that surrounds them. What lies above the earth forever out of reach. From moons, to stars, galaxies, and beyond.
The Most Mysterious Signals from Deep Space Detected in 2026
The year 2026 has reinforced a long-standing truth in astronomy: the deeper we listen to the Universe, the stranger it becomes. Modern telescopes no longer simply observe distant stars and galaxies — they intercept brief, powerful, and often inexplicable signals that arrive from billions of light-years away. Some last only milliseconds, others pulse with eerie regularity, and a few originate from epochs when the Universe itself was still young.

ESA's Solar Orbiter has made new measurements that illustrate the chaotic origins of solar flares.
There is no big bang at the start of a solar flare. They begin modestly. In actuality, the early warning indicators were hardly noticeable to scientists until recently.

Exoplanets That Defy Classification — Even in Theory
In 1990s, many expected them to resemble familiar worlds: rocky planets like Earth, gas giants like Jupiter, or icy bodies similar to Neptune. The assumption was simple—different systems, same basic categories. Reality, however, turned out to be far more imaginative.

Worlds with an Extremely Short Daylight Cycle
On Earth, the rhythm of life is deeply tied to a simple and familiar pattern: day follows night, night follows day, and one full cycle takes 24 hours. This steady cadence has shaped everything from human biology to global climate systems. But beyond our Solar System, this comforting regularity quickly breaks down. In the vast diversity of exoplanets discovered so far, astronomers have identified worlds where daylight lasts only a few hours—or even less. On such planets, the Sun barely rises before it sets again, and the very concept of a “day” becomes something alien.

Exoplanets That Survived Planetary Collisions
When we imagine planets, we often think of calm, stable worlds tracing predictable paths around their stars for billions of years. But the reality of planetary systems—especially in their early stages—is far more violent. Young systems are chaotic environments where worlds migrate, gravitationally interact, and sometimes collide at unimaginable speeds. Remarkably, some exoplanets we observe today appear to have *survived* massive collisions with other planets, carrying the scars of ancient cosmic disasters.

Worlds Where the Night Is Hotter Than the Day
On Earth, the rhythm of temperature feels intuitive. When the Sun rises, the ground warms. When darkness falls, heat slowly leaks back into space. Day means warmth; night means cooling. This pattern is so deeply ingrained in our everyday experience that it feels almost universal. Yet beyond the Solar System, astronomers have discovered worlds where this logic completely breaks down. On some distant planets, night is not a time of cooling at all. Instead, the darkness can be hotter than the blazing day.

The concept of human reproduction in space is rapidly becoming a reality.
One uncomfortable subject is becoming more difficult to ignore as spaceflight transitions from infrequent government missions to something more akin to everyday travel and employment: what happens to human reproductive health when we are away from Earth?

The Last Sunrise on Mars
The red dust stretched endlessly under the thin Martian sky, glowing softly as the first rays of the sun crept over the horizon. Commander Tariq Alvi stood on the observation deck of the settlement, his gloved hands pressed against the cold, reinforced glass. This was the moment he had been waiting for—the last sunrise he would witness on Mars before returning to Earth.

Why Some Exoplanets Look “Puffed Up”
When astronomers first began discovering exoplanets—planets orbiting stars beyond our Solar System—they expected familiar patterns. Some worlds would resemble rocky Earth-like planets, others would look like gas giants similar to Jupiter or Saturn. Instead, the universe delivered a surprise. Among thousands of known exoplanets, scientists found a strange class of worlds that appear abnormally large, swollen far beyond what their mass should allow. These planets look “puffed up,” like overheated balloons floating in space.
