NEW YORK: The 13.8 billion year old universe houses more than 100 billion galaxies. How galaxies form and develop is a question that has puzzled scientists for a long time. This discovery may shed some light on the issue. A study on the discovery was published in the journal Astronomy and Astrophysics.
Lead author of the report, Hervé Dole , said “Finding so many intensely star-forming, dust galaxies in such concentrated groups was a huge surprise. We think this is a missing piece of cosmological structure formation.”
European Space Agency’s Planck and Herschel telescopes spotted these galaxies which came into being roughly three billion years after the Big Bang, which was 13.8 billion years ago. Using the cosmic microwave background signals, Planck was able to develop a map of the radiation left by the Big Bang.
