J1025 + 1402, one of the three little galaks of red dot seen up to 2.5 billion years of light

An odd type of galaxy seen in the early universe found today with a most recent part of the cosmos, which asks about their true nature.
In the past few years, astronomers who use Trielopyo at James Webb Space (JWST) saw many small, compact and red things from the first billion years in the universe, known to be known A little red dot (LRDS). They think involved in some process in the early universe, like the birth of supermssless black holes found in the center of most galaxies, including ourselves.
Xiaojing Lin At Tsinghua University in China and his colleagues now find an unusual discovery, finding LDS in a more new universe, about 12 billion years after Big Bang. “Discover describes the conditions that give the little red dot are exclusively exclusively in the early universe,” Lin said.
The team watches images taken by Sloan Digital Sky Survey using a New Mexican telescope. They learned three things JWST saw like LRDs, but, at times, up to 2.5 billion years away.
“They fit each other definition of small red dots,” as a team member Xiaohui Fan at the University of Arizona. “I don’t think there’s any doubt that they are very similar.”
Each of the LRDs is estimated to be about one million times more than our day, with width equal to our solar system. One of them is called “egg” because of this form. The team finds a handful of other LD candidates who have not confirmed.
Discovering is interesting, says Anthony Taylor At the University of Texas in Austin, because we can take us unequal information in nature with LDS. Things close to telescopes like jwst and hubble should learn more easier than the first universe, which is better than what they are.
“They are closer to us, so they appear brighter,” Taylor said.

A possible clarification of lrds so they represent Early stages of a supermassive black hole Grows within a galaxy, maybe when it first flows and begins to repair food material.
It is unclear when local LDS can be galaxies that are hidden so far, or recently formed and just start eating with many materials. “It’s too early to say that ahead,” Taylor said.
The fan says they hope to get a hubble or jwst time to observe these local LDS in more detail. “We have a suggestion for the hubble we are waiting to be approved.”
It is possible for LDS to exist in the entire history of the universe, not only in local and ancient cosmos. “They sat there hidden in simple sight,” Fan said. “People don’t know what they’re looking for.”
