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.

So that galaxy is 13 billions of years old. I wonder if it’s dead now. Shouldn’t we see dying galaxies all over the place?
There is that. But in the Hebrew it’s “Be light”.
MACS1149-JD1, is an impersonal name. They should call it something else, like Helen Thomas.
Whatever it is, however it came about, given the laws of physics, we can never visit them and whoever is there can never visit us. Also given the distance it would take tens of millions of earth years for a radio signal to reach them and then tens of millions of years for a return signal to reach us. Its safe to say each will not be a threat to the other.
Also really don’t know for certain what is being “seen” with that telescopic instrument. Those “pictures” are computer generated based on software that feature logarithms that reflect the beliefs of the scientists that programmed them.
If they are receding away from us, or we from them, they will fade into oblivion and we will never know..................
True, but that is looking at the situation with present day technology.
It was once believed that man could never travel faster than 60 miles per hour or he would suffocate from not being able to breathe at that fantastic speed...............
From SCTV Dave Thomas as Father Doyle reading from First Chrysanthemums:
“In the beginning, there was nothing. The Lord said, ‘Let there be light.’ Then there was still nothing. But you could see it.”
Sounds like we’re just waiting for the Gnab Gib.
Our life span and the miniscule galactic time we've spent observing are too short to recognize galaxies growing or dying. Nebulae might be precursors to new galaxies, or the remains of dead ones. If we're still around in a billion years or so, we'll know.
Someones always gotta find a way to put Johnny Depp into the conversation. The trial's over. Get over it already.
How far is the most distant non-rotating galaxy?
Pirates of the Milky Way!......................
Isn’t that what he wrote?
We're seeing it as it was 13 billion years ago. Yes ... it may well be "dead" now ... Only God (and its inhabitants, if any) know.
No the Big Bang is only man’s attempt to explain the unexplainable. I like the steady state universe theory and the apparent expansion is due to a defect in the speed of light. This is why objects further away from us seem to be going away from us the fastest.
I think Hans Lippershey might have said that first ...

In the beginning, there was nothing, and then it exploded.
