This discovery also demonstrates how collaboration between telescopes and research teams can unlock some of the cosmos’s most elusive secrets. With further studies, astronomers hope to map more of these hidden filaments, ultimately leading to a clearer picture of how our 13.8 billion-year-old universe came together., The results were clear: Approximately 76% of the universe's baryonic matter lies in the IGM. About 15% resides in galaxy halos, and a small fraction is burrowed in stars or amid cold galactic gas., 'The models were right!' Astronomers locate universe's 'missing' matter in the largest cosmic structures; Astronomers discover dark matter 'bridge' linking colliding galaxies: 'This is the missing , With the help of powerful bursts of radio waves emanating from 69 locations in the cosmos, researchers now have found the "missing" matter., Cambridge, MA— A new landmark study has pinpointed the location of the Universe's "missing" matter, and detected the most distant fast radio burst (FRB) on record. Using FRBs as a guide, astronomers at the Center for Astrophysics | Harvard & Smithsonian (CfA) and Caltech have shown that more than three-quarters of the Universe's ordinary matter has been hiding in the thin gas between , .
