(Image credit: Joseph DePasquale/Space Telescope Science Institute/Davide Tornotti/University of Milano-Bicocca) For the first time, we could trace the boundary between the gas residing in galaxies and the material contained within the cosmic web through direct measurements. Astronomers have imaged a spectacular thread in the cosmic web, connecting two actively forming galaxies that existed when the universe was just 2 billion years old. Both galaxies at hand are home feeding supermassive black holes. The cosmic web stretches for an incredible 3 million light-years, making it about 3...
