Scientists have calculated the rotation speed of the galaxy MACS1149-JD1, which is 13.6 billion light-years from Earth.
According to the Interfax news agency, the speed of rotation of the most distant from the Earth galaxy MACS1149-JD1 was calculated using the Atacama Desert telescope by scientists from Britain and Japan.
The experts talked about the redshift effect, in which the range of long wavelengths shifts depending on the galaxy's distance.
"JD1's rotational speed is much slower than that of galaxies of later epochs and our Galaxy, and it is likely that JD1 is in the early stages of rotational motion," the scientists reported.
According to calculations, the rotation speed of MACS1149-JD1 is about 50 kilometers per second. For comparison: the speed of rotation of the Milky Way is 220 kilometers per second.
In addition, scientists have measured the diameter in the cross section of the most distant galaxy. It was 3 thousand light years, which is significantly less than the diameter of our galaxy.
