About 3 billion years after the Big Bang. At this moment the first three-dimensional map of the universe starts, carried out by a team of scientists from the Max Planck Institute for Astronomy (Germany).
The vast map in question is millions of light-years across and shows the enormous structures of the cosmic web , thanks to data collected by the WM Keck Observatory, home to the two largest telescopes in the world. This cosmic network, whose filaments span hundreds of millions of light years, is what makes up the matter of the universe where dark matter would symbolize the backbone of this network.
The map, created by using subtle background galaxies as light sources, reveals a 3D section of the universe 11 billion light years away , also showing the early stages of the formation of this cosmos structure, the early years of an adolescent universe.
The data for the creation of this map, created with a novel computational algorithm, was obtained using the LRIS spectrograph on the Keck I telescope which, thanks to its gigantic 10-meter diameter mirror, peeks galaxies much fainter and smaller than stars almost Lichs that we can see with the naked eye.
