: Astronomers analyse huge, hot filament of missing normal matter
Thu 19 Jun 2025; A European team of astronomers led by the Netherlands have uncovered a large filament of hot gas connecting four galaxy clusters. The filament contains so-called warm-hot intergalactic medium. The hot gas spans over a distance of 23 million light years, is more than ten million degrees hot, and may be part of the missing normal matter. The team used two X-ray space telescopes: the Japanese Suzaku and the European XMM-Newton. They publish their findings today in the journal Astronomy and Astrophysics.
