The LZ detector, located 1.6 km underground, recorded a single event on June 16, 2023, that cannot be explained by known models. The significance is about 3 sigma, which is below the discovery threshold.

Astronomers have presented HiPERCAM and Hubble data indicating the absence of stars in the Cloud 9 object, located 14 million light-years away. Final confirmation is expected from the James Webb telescope.

Chinese astrophysicists published a study in Physical Review Letters reporting a gamma-ray signal from 15.5 years of telescope data that matches the annihilation of WIMP particles. The scientific community calls for caution due to previous false positives.

Astronomers have discovered a stellar stream beyond the Milky Way for the first time in the galaxy UGC 9050-Dw1. This discovery allows streams to be used for mapping dark matter in other galaxies.

🌍 Earth as a dark matter detector: physicists propose using the planet to search for hypothetical particles. The study showed strict constraints for axions and candidates for dark photons, but additional observations are required. 🔬📡 #science #darkmatter #physics

Dark matter may be hiding in the fifth dimension! 🌌 A new theory by physicists explains why we cannot detect it: interaction with our reality weakened sharply as the Universe expanded. 🧠🔬

Physicists from the University of British Columbia have proposed a new theory: mysterious 'dust particles' that knock out beams in the Large Hadron Collider could be a consequence of dark matter passing by. Kilogram-sized clumps of axion quark matter, passing through the Earth, create acoustic waves that shake dust off the walls of the accelerator. 🌌🔬

British scientists have proposed a new theory explaining the nature of dark matter through the fifth dimension. The study, published in Physical Review D, solves the problem of "artificial fine-tuning" of particle masses and explains why dark matter became passive. 🔬🌌
