The Subaru Telescope observed the interstellar comet 3I/ATLAS (C/2025 N1) on January 7, 2026 (UT), after it made its closest approach to the Sun. By observing colors in the coma around the comet, astronomers could estimate the ratio of carbon dioxide to water. This ratio is much lower than that inferred from earlier observations by space telescopes. These findings suggest that the chemistry of the coma is evolving over time and offers clues to the structure of comet 3I/ATLAS.

New hydrodynamical simulations explain how tidally destroyed stars reveal hidden supermassive black holes and why no two of these cosmic collisions look the same.

Several contaminants, including traces of ink, originating in the preparation of subsamples, have been identified in Martian meteorites by the EHU’s research group. The finding highlights the importance of stricter protocols to prevent misinterpretations of the composition of these rocks and to ensure the reliability of future studies and Mars sample-return missions.

Curious how 6G will power unmanned operations in remote spots like mining sites or disaster zones? A new Engineering study designs 6G space-air-ground integrated networks around the SC³ loop, a reflex arc-like structure, ditching traditional link-focused 5G designs. It tests a task-oriented framework that cuts control costs and tackles key 6G network challenges for autonomous systems.

A research paper by scientists from Chinese Academy of Sciences proposed a hybrid frequency–phase–space encoding method, integrated with high-density electroencephalogram (EEG) recordings, to develop high-speed BCI systems.

The new research paper, published on Mar. 26 in the journal Cyborg and Bionic Systems, developed a groundbreaking visual brain-computer interface (BCI) that sets a new benchmark for noninvasive BCI communication speed.

6G’s space-ground integrated networks need reliable simulation tools for LEO satellite mega-constellations. A new study in Engineering unveils UltraStar, a high-fidelity simulator that models dynamic satellite topologies, real communication conditions and boosts efficiency via parallel computing. It’s validated across network layers and paves the way for 6G space-ground network development.
