Paris (AFP) Astronomers have observed for the first time a “bubble of galaxies,” a huge mass whose origins date back to the early ages of the universe, regarding 14 billion years ago, according to a study published in the Astrophysical Journal. Because it is not possible to see it with the naked eye, it is assumed that the bubble is a mass with a diameter of one billion light-years, that is, ten thousand times larger than the Milky Way galaxy. French researcher Daniel Pommarid, an astrophysicist at the Atomic Energy Authority, who participated in preparing the study, said: This cluster is located in what astronomers call the near universe, regarding 820 million light-years from the Milky Way, and can be described as a “spherical shell with a core.”
