James Webb at the dawn of the Universe discovered the beginnings of filament-like structures based on dark matter 3 million light years long

James Webb was able to look again into the early Universe. The space telescope saw the beginnings of a structure called the cosmic web.

Here's What We Know

Scientists using a new $10 billion space observatory have been able to see what was happening in the universe 830 million years after the Big Bang. The telescope saw the beginnings of the cosmic web, which is a structure based on dark matter.

Science says the cosmic web is formed by quasars and supermassive black holes. A space telescope observed quasar J0305-3150. It appeared to have 10 galaxies connected by a string 3 million light years long. For a better understanding of scale, the Milky Way is nearly 106 000 light-years wide and Andromeda is 220 000 light-years long.

Over time, the discovered cosmic web will grow stronger and become a giant cluster of galaxies. Studying it early in its life cycle will reveal more about such processes by observing its evolution.

James Webb discovered the cosmic web as part of A SPectroscopic survey of biased halos In the Reionization Era (ASPIRE). The programme aims to study the first black holes, observing 25 quasars that existed during the first billion years after the creation of the Universe.

With the completion of ASPIRE, scientists are expected to discover how supermassive black holes appeared less than 1 billion years after the Big Bang. According to current scientific theories, the Universe simply did not have the material to form them at that stage of the Universe's evolution.
