Recently, scientists have used models to explore the appearance of the universe at the beginning of about 12 billion years ago, and for the first time saw a "cosmic web" composed of bright threads of hydrogen.
Not only that, they also found that the bright light of the cosmic web comes from billions of dwarf galaxies that have not been observed before.
According to reports, the observed "cosmic web" is part of Hubble's ultra-deep field.
The Hubble ultra-deep field is the deepest point observed in the universe so far.
Scientists have inferred the existence of a "cosmic web" through the universe model a long time ago, but they have never directly observed or captured images before.
Most galaxies, including our galaxy, were born on the "cosmic web."
These bright filaments are the gas that produces galaxies, which only existed in the 1 to 2 billion years after the Big Bang. Now, through the European Southern Observatory's "Very Large Telescope" (Very Large Telescope) 8 months of observation plus long After 1 year of data processing, the "universe network" finally appeared.
But scientists say that the biggest surprise is not the discovery of the "cosmic web" itself, but simulations showing that the light from the "cosmic web" comes from billions of previously invisible and undiscovered dwarf galaxies.
The related research results were published in the journal "Astronomy and Astrophysics", marking the first observation of the light emitted by the "Cosmic Net" itself.
