    Astronomers have discovered one of the first galaxies in the universe: it has its own characteristics (video)

    This is the youngest galaxy in which scientists have been able to measure its rotation speed.

    A team of Japanese astronomers from the University of Tokyo, using the ground-based ALMA telescope, discovered a small galaxy that is 13.3 billion light-years away from us. This is one of the very first galaxies in the early universe. Scientists even managed to measure the speed of its rotation, but it turned out that it is much less than that of the Milky Way, according to ScienceAlert.

    The galaxy, which has been named MACS1149-JD1, is extremely far from Earth and too dim for telescopes to pick up its light. Scientists were able to detect the light from this galaxy thanks to a cluster of galaxies, which is much closer, and it increased the incoming radiation like a lens.

    According to scientists, the MACS1149-JD1 galaxy already existed when the universe was only 500 million years old. Therefore, it is one of the youngest galaxies known to science. Scientists have found that the MACS1149-JD1 galaxy is only 3,000 light-years across. For comparison, the diameter of the Milky Way is 100 thousand light years.

    All galaxies in the universe rotate at a tremendous speed. Our galaxy rotates at a speed of 200 km/s. But as a result of observations, scientists created a rotation model of MACS1149-JD1 and found that its speed is only 50 km/s.

    According to scientists, this is the first youngest galaxy in which it was possible to measure its rotation speed. But how do galaxies pick up higher speeds over time as they spin? This question is answered by a new study.

    “The speed of this galaxy is much lower than that of known galaxies that appeared much later. We believe that this galaxy is at the initial stage of its evolution. Accordingly, its rotational movements are only gaining strength. This may mean that initially small galaxies overgrow with large amount of matter and rotate much faster after billions of years,” says Akio Inoue of the University of Tokyo.

    Scientists now hope to use the new Webb Space Telescope to further study this and other early galaxies to learn more about their evolution and change in rotation speed.

    As Focus already wrote, on July 12, the full-fledged scientific work of the Webb telescope in space began. This date can be considered the beginning of the scientific activities of the obsevetory, because it was on this day that NASA showed the first detailed photographs of space objects that Webb took after preparing for work.

    We remind you that astronomers managed to detect an object with the strongest magnetic field in the Universe. This neutron star, which is a pulsar, has a magnetic field strength of 1.6 billion Tesla. For comparison, the magnetic field strength of a typical refrigerator magnet is approximately 0.001 Tesla.
