Challenging a Cosmic Assumption (Image Credits: Unsplash) Astronomers have long assumed that supermassive black holes lurk at the heart of nearly every galaxy, but recent observations challenge that view for the universe’s smaller cosmic structures. Challenging a Cosmic Assumption Researchers uncovered a surprising gap in the distribution of supermassive black holes when they analyzed data ...

'It would be a fundamental breakthrough': Mysterious dark matter may interact with cosmic 'ghost particles'

Breaking New Ground with XRISM’s Precision (Image Credits: Scx1.b-cdn.net) Astronomers recently achieved a milestone in cosmic observation with unprecedented clarity into the heart of a distant galaxy dominated by a supermassive black hole. Breaking New Ground with XRISM’s Precision The XRISM space telescope, a collaborative effort by international space agencies, delivered its most detailed X-ray ...

A Rogue Planet Stops Hiding as Astronomers Crack a Cosmic Mystery

Sumi

Astronomers have achieved a milestone in planetary science by measuring both the mass and distance of a rogue planet — a world drifting alone through the Milky Way without orbiting any star. Using a rare combination of ground-based observatories and the Gaia space telescope, researchers were able to overcome a long-standing challenge in detecting such ...

Why AI Can’t Even Tell If Writing Was Done by AI

Sumi

As artificial intelligence becomes better at writing text that sounds human, the tools we use to detect AI-authored writing are struggling to keep up — even when those detection tools are powered by AI themselves. Despite widespread interest from educators, journalists and platforms seeking to flag or label automated content, researchers say that distinguishing AI-generated ...

Humans Have Imagined Artificial Intelligence for Centuries Long Before Chatbots Were Born

Sumi

From ancient mythmakers to modern technologists, the idea of artificial intelligence — machines or beings with human-like thought — has captivated and unnerved people for millennia. A new historical survey shows that **stories about human-created automatons, thinking machines and artificial humans stretch back to ancient Greece, resurfacing through folklore, religion and early science fiction long ...

West Antarctic Ice Melt Threatens Land and Lives

Sumi

If the world’s climate continues warming, West Antarctica’s massive ice sheet could not only raise global sea levels but also trigger dramatic geological upheaval beneath the continent, new research suggests. Scientists studying sediment cores from the seafloor and ancient climate records have uncovered evidence that when this ice sheet collapsed repeatedly in the past, the ...

Scientists Hear Nothing Alien in 3I/ATLAS Radio Scan as Comet Mystery Deepens

Sumi

Since its discovery in July 2025 as it sped through our solar system at interstellar velocities, the object known as 3I/ATLAS has ignited both scientific curiosity and wild speculation about its origins — from natural comet to hypothetical alien probe. But recent deep scanning for technosignatures, part of an international effort to test whether the ...
