Objects at high redshifts can be detected only by infrared light, which is why Webb was crucial in observing these 87 galaxies. By comparison, thesees only from ultraviolet to near-infrared light, which is why astronomers previously thought there were very few galaxies beyond redshift 11.
"I believe this discovery is just the tip of the iceberg because the data we used only focused on a very small area of the universe," Yan said in the statement."After this, I anticipate that other teams of astronomers will find similar results elsewhere in the vast reaches of space as [Webb] continues to provide us with a new view of the deepest parts of our universe."
