For the first time, researchers at CERN have transported trapped antiprotons by road inside a cryogenic trap — a carefully staged test that opens routes for precision antimatter... 三月 26, 2026

A bright, short radio burst—called a 'mega‑laser'—was detected by South Africa's MeerKAT and traced to a merging galaxy 8+ billion light‑years away. Astronomers say the signal i... 三月 23, 2026

On 17 March 2026 CERN's LHCb experiment announced the discovery of Xi-cc-plus, a proton-like particle four times heavier than the proton. The find, enabled by an upgraded detect... 三月 18, 2026

A rare interstellar visitor, 3I/ATLAS, has produced an unexpected sunward glow that has left scientists baffled. New multi‑telescope data shows unusual chemistry and morphology;... 二月 17, 2026

Ultraviolet light is exposing a hidden layer of colour across the animal kingdom — from scorpions and flying squirrels to platypuses and reef fish — and scientists are racing to... 一月 28, 2026

Researchers at SLAC/Stanford used powerful X-ray beams to read hidden Greek astronomical notes beneath a medieval palimpsest, recovering star coordinates from Hipparchus—the old... 一月 24, 2026

A practical guide to how researchers extract, identify and quantify microplastics from water, sediment and biota — and why choices in digestion, density separation and spectrosc... 一月 18, 2026

NASA’s Europa Clipper and other spacecraft have returned ultraviolet views of the interstellar comet 3I/ATLAS, validating flight hardware and mapping gas and dust while coordina... 一月 09, 2026

NASA's SPHEREx mission has completed a full-sky survey in 102 infrared bands, producing a multilayered cosmic atlas that scientists say can turn a flat star chart into a 3D map ... 十二月 20, 2025

New images and telescope data show interstellar visitor 3I/ATLAS sporting a rare sunward anti‑tail whose orientation has shifted as the object nears its closest approach on 19 D... 十二月 15, 2025

New JWST spectra have highlighted a handful of ultra‑distant, compact objects whose light matches predictions for hypothetical dark‑matter‑powered 'dark stars' — but the signal ... 十一月 19, 2025

NASA will host a live briefing on Nov. 19, 2025 to release new images of the interstellar comet 3I/ATLAS. Here’s when to tune in, what instruments produced the pictures, and wha... 十一月 18, 2025

Elon Musk warned on a recent podcast that the interstellar visitor 3I/ATLAS—while almost certainly not aimed at Earth—would be catastrophic if it ever struck the planet. Scienti... 十一月 17, 2025
