Dark Matter May Replace Black Hole at the Milky Way's Core, Astronomers Suggest New Astronomical Research Challenges Long-Held Assumptions about Sagittarius A* Astronomers suggest that the heart of the Milky Way may not host a supermassive black hole, but instead a vast concentration of enigmatic dark matter producing an equivalent gravitational pull. They argue that this unseen material — believed to account for most of the universe's mass — can explain both the intense motions of stars just light-hours from the galactic center and the smoother, large-scale rotation of matter across the Milky Way's outer regions. The findings were published yesterday in Monthly Notices of the Royal Astronomical Society . Rethinking the Milky Way's Dark Heart The findings challenge the prevailing view that Sagittarius A* (Sgr A*) , the proposed black hole at the center of our galaxy, governs the motion of the so-called S-stars — stellar objects that race around the core at staggering ...

JWST May Unveil 'Dark Dwarfs': First Stars Powered by Dark Matter at Our Galaxy's Core Celestial bodies termed "Dark Dwarfs" may lie concealed at the heart of our galaxy, potentially offering crucial insights into one of cosmology's greatest enigmas — dark matter . A New Class of Celestial Bodies: Dark Dwarfs Discovery and Terminology A team of researchers from the UK and Hawaii has, for the first time, described these objects in a paper published in the Journal of Cosmology and Astroparticle Physics . The study outline how their existence might be confirmed using current instruments such as the James Webb Space Telescope. The paper is entitled " Dark Dwarfs: Dark Matter-Powered Sub-Stellar Objects Awaiting Discovery at the Galactic Centre. " The Anglo-American research team coined the term "Dark Dwarfs" —not due to the objects lack of luminosity, but owing to their unique association with dark matter, a central focus in modern cosmology a...
