Detection of pure warm-hot #IntergalacticMedium emission from a 7.2 Mpc long filament in the Shapley supercluster using X-ray spectroscopy: https://www.aanda.org/articles/aa/full_html/2025/06/aa54944-25/aa54944-25.html -> Astronomers have discovered a huge filament of hot gas bridging four galaxy clusters: https://www.esa.int/Science_Exploration/Space_Science/XMM-Newton/The_models_were_right_astronomers_find_missing_matter - at 10 times as massive as our galaxy, the thread could contain some of the Universe’s ‘missing’ matter, addressing a decades-long mystery.
