Jwst is a huge spiral of galaxy in cosmic history
The “big wheel” nickname, spiral-shaped drive galaxy galaxy passed two thousand years in Big Bang
A giant spiral of galaxy, the nickname of the “big wheel”, when he saw James Webb’s Space telescope after two billion years. Wheeled-star disk stars extend in more than 100,000 years, another galaxy disc from this cosmic time is greater than a disk.

NASA JAMES website Telescope (JWST) A new object in the beginning of the universe is like the form of galaxies. The “big wheel” named it is like a galaxy Our own milk mode– Star, gas and cosmic dust disk humor, gas and dust. But the big wheel is bigger than our home galaxy; Five times are more massive and covers two times.
The strangest thing about the big wheel is also not his size but also his size. Jwste saw the universe for about two million years old, very young for a great galaxy.
It should usually take the whole age of the universe to be so large, says Sebastiano CantalupoAn astronomer at the University of Milan-Bicocco in Italy, who wrote the last time Nature astronomy paper around the discovery. The contemporary contemporary of the time is much smaller and much smaller, “you can clearly see that large wheels are true,” he noted.

The discovery is part of a wider tendency in astronomy, greater than ever and the most important telescopes look deeper in the universe, with more and more light from cosmic views. Using JWST and other powerful facilities, observers could see some Galaxy early Galaxy, says Big Bang Vadim SemenovDoctoral researcher at the Astrophysics Center Harvard & Smithsonian. Semenov, who did not participate in the new study, warns that it is “one of the extremes of the galaxy” Early universeThis process “would be much more powerful and chaotic, driven by the rapid acretions of the material of the material of the material of the intergalactic spaces.”
All this primordial intensity comes from the small size of the early universe that had a higher density of raw materials that coalegate the galaxies. The neighborhood lives in the big wheel, which is already enriched to this cosmic time is the excessive extra shipyard. That’s probably the “heavy breakfast” lies Chuck SteidelLearning cooperation and an astronomer at the California Institute of Technology. According to Steidel, the big wheel is “as biggest in the block and ate breakfast for everyone else … he looks like an adult galaxy.
Analysis lead Author Soft wangHe was the first to noticing the great wheel of the JWst data researcher at the University of Milan-Bicocco. Initially, the galaxy thought it was an essential distraction for studies on this special patch in the beginning of the universe. The giant spiral was not there, so Wang assumed a much time later, in the cosmic time of Jwst’s point of view. In more analyzes, however, Wang and his colleagues were able to measure the real cosmic distance of the big wheel, and suddenly realized that the object was seen that the distance was really distant galaxy, very fast, very fast, “he said.
But there is still clearly what is so fast so fast so fast. The growing galaxy matter is a tendency to power intense radiation, fueling with the edges of star formation and semi-holes from the malicious nutrition; Such explosives can cut the flow of inappropriate issues, away from forming the formation of the material and increasing more growth. “At the moment, I have to say that it is mystery – whole mystery,” Cantalupo admitted. Maybe, he said, that Big Wheel’s environment can be crowded in “pre-unknown some physical mechanisms (support) to grow galaxies.”
Semenov offers gardening analogy: “It’s like entering a spring garden and knowing a great fruit you would expect at the end of summer,” he noted. “We need the theoretical and numerical studies that exist in the” existing models that can explain such galaxies, extreme galaxies and the extreme galaxies that live. “
So, as we have had a big wheel about 12 million years ago, what can we say about the situation today in our current cosmic age? There is no certainty, Steidel says, but his heavy situation and compact population of population indicates that the external object can eventually be another cosmic form. It may become a huge elliptical galaxy, a collection of star billion pickups. When numerous galactic fusions occur, this type of galaxy usually occurs.
“When we look into a set of galaxies in the galaxies, they are almost elliptically, so they are old, and the stars seem to be blurred balls,” he said. “They don’t seem to disks, but we don’t know what their story is. So there were (known galaxies) where there could be a descendant of things like big wheels.”
“One of the fun things about astronomy is that you find things you were looking for, and sometimes they are more interesting than you were trying,” Steidel says. “It’s not the right path all the time, and (the big wheel) I would call a serent discovery. Now we know what we look for …, I think it will be quite interesting.”
