A galaxy about 13.3 billion light-years away (inset in this image of a galaxy cluster from the Hubble Space Telescope and the Atacama Large Millimeter/submillimeter Array) is the most distant galaxy to show signs of rotation.
======================================================================
There is a galaxy spinning like a record in the early universe — far earlier than any others have been seen twirling around.
Astronomers have spotted signs of rotation in the galaxy MACS1149-JD1, JD1 for short, which sits so far away that its light takes 13.3 billion years to reach Earth. “The galaxy we analyzed, JD1, is the most distant example of a rotational galaxy,” says astronomer Akio Inoue of Waseda University in Tokyo.
“The origin of the rotational motion in galaxies is closely related to a question: how galaxies like the Milky Way formed,” Inoue says. “So, it is interesting to find the onset of rotation in the early universe.”
JD1 was discovered in 2012. Due to its great distance from Earth, its light had been stretched, or redshifted, into longer wavelengths, thanks to the expansion of the universe. That redshifted light revealed that JD1 existed just 500 million years after the Big Bang.
Astronomers used light from the entire galaxy to make that measurement. Now, using the Atacama Large Millimeter/submillimeter Array in Chile for about two months in 2018, Inoue and colleagues have measured more subtle differences in how that light is shifted across the galaxy’s disk. The new data show that, while all of JD1 is moving away from Earth, its northern part is moving away slower than the southern part. That’s a sign of rotation, the researchers report in the July 1 Astrophysical Journal Letters.

Wondering if it’s still there.
No, it moved........................
Point the Webb telescope at it
It almost seems as if the Hubble will become a ‘finder’ for interesting things to point the Webb at!
Have to ask where the thingie that went blooie came from to produce all this.
Well, some theorize that there was a “Big Crunch” before the Big Bang.
And that the Universe goes thru cycles of Expansion and Contraction, ad infinitum........................
This IS from the Webb!......................
Sounds plausible, sorta like the universe is breathing.
And yet the speed at which the universe is expanding is increasing.
Seems counterintuitive, no? Given that the next scheduled event is a contraction or crunch?
“The new data show that, while all of JD1 is moving away from Earth, its northern part is moving away slower than the southern part.”
???
Like a Yo-yo or a trampoline it speeds up until it reaches the end of its gravitational ‘rope’................
IOW, it’s spinning...................
They’ve finally found intelligent life out there? ;)
Sorry, Red, but nope.
"Now, using the Atacama Large Millimeter/submillimeter Array in Chile for about two months in 2018, Inoue and colleagues have measured more subtle differences in how that light is shifted across the galaxy’s disk.However..."The James Webb Space Telescope will observe JD1 in the next year to reveal more clues to how that galaxy, and others like ours, formed."
The large pic is from Hubbell, the inset is from Webb................
Agreed. IMHO that puts to rest the oscillating universe theory. So yes, there was a big bang a long time ago, before even Joe Biden was born. But it was probably a one-time event.
Four simple words.
"Let there be light!"
Aye, therin lies the rub.
Expansion would seem to be infinite. Yet it has to slow down at some point. Perhaps.
Where does dark matter fit in? Does it? I too believe this iteration of the universe to be a "one off".
