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 ...
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 ...
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 ...
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 ...
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 ...
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 ...
When most stars die, they go out with a bang — exploding in brilliant supernovae that scatter heavy elements across space and light up the cosmos. But astronomers have identified a less violent end for certain stars, where they instead fizz out in complex, filament-laden outflows powered by dense winds. These “failed explosions” offer scientists ...
For centuries, Neanderthals have been cast as brutish Ice Age relatives of Homo sapiens, but the discoveries of 2025 continue to overturn old stereotypes while revealing surprising new facets of their lives. From evidence of advanced behaviors and survival strategies to biological differences that may have influenced their fate, this year’s research is painting a ...
For more than a century, scholars, cryptologists and history buffs have been captivated by the Voynich Manuscript — a hand-drawn, illustrated codex written in an undeciphered script that has defied translation since its modern discovery. Radiocarbon dating places its vellum in the early 15th century, and its pages depict bizarre plants, astrological signs and enigmatic ...
For centuries archaeologists have unearthed lost civilizations — from Maya metropolises to submerged Mediterranean towns — but some cities recorded in historical texts remain stubbornly hidden from the present day. Despite ancient inscriptions, royal records and historical chronicles confirming their former existence, at least six major urban centers have never been pinpointed by modern excavation ...
