Astronomers have made a significant discovery with a veteran X-ray telescope. They’ve found a massive filament of hot gas that weighs in at ten times the mass of our galaxy. This could help explain some of the universe’s so-called “missing” matter. This finding suggests that our current model of the cosmos is still on track, giving us fresh insights into the mysteries of the universe.
