The Enormous Gas Filament Mirages Galaxy Clusters

ESA's XMM-Newton

For the initial time, ESA's Planck space telescope has been detected a bridge of hot gas between a pair of galaxy clusters 10 million light-years apart. A bell 399 and a bell 401, each containing 100’s of galaxies, are billions of light years a path. The being there of hot gas linking them had previously been oblique at in X-ray data from ESA's XMM-Newton, but is now established."Planck is helping to expose hidden material between galaxy clusters that we couldn't observe clearly before," says James Bartlett scientist of NASA's Jet Propulsion Laboratory.

In the before time universe, filament of gaseous matter pervaded the space in a giant web, with clusters finally forming in the densest nodes. The gas that remains is easiest to spot between interact galaxy clusters, where the filament are dense and heated up.
