Credit: Reiprich et al., Astronomy & Astrophysics In physical cosmology, galaxy filaments are massive, thread-like formations that form the boundaries between large voids in the universe. The filaments consist of gravitationally bound galaxies. In recent, a team led by the University of Bonn has- for the first time- discovered a gas filament with a length of 50 million light-years. Its structure is strikingly similar to the predictions of computer simulations.  Scientists examined a celestial object called Abell 3391/95, a system with three galaxy clusters. It is approximately 700 million light-years away from Earth.
