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.

The universe is a Kline jar.🤔
These scientists sound so foolish when they make these statements. The furthest lights are 13+ billion light years away, so they assume the galaxy is 13+ billion years old. To get that, you have to assume the galaxies travels at or near the speed of light. You have assume we are at the center of the universe, since we can see galaxies at that distance in all directions.
How can we assume light from the furthest seen galaxy to our west hasn't reached the furthest seen galaxy to the east? That would make the universe at least 26+ billion years old.
The movie may be closer to the actual truth!.....................
Naturally, young galaxies, especially female ones, love to dance and twirl around...
Np biggee...
It’s still probably not getting its forwarded mail.
Yep, wouldn’t ant to miss that Publisher’s Clearinghouse stuff!....................
