Astronomers opened a large copy of the Milky Way. Early Universe 21:09

Italian astronomers from the University of Bicocus University of Bicocus discovered a large galaxy that emerged only 2 billion years after the Big Explosion, along with colleagues from the USA, the Netherlands and other countries. This enormous structure, which is called the “big wheel ,, was opened using the James Webb space telescope. The results of the study were published there magazine Nature astronomy (Natastro).

A large wheel is similar to the Milky Way, but is a huge disc galaxy, three times larger than other galaxies of the same period. The light traveled for more than 12 billion years to reach the soil that allowed scientists to look at the early universe. The galaxy has maintained its spiral structure despite the rapid growth and high speed that contradicted the existing models of the formation of galaxies.

Typically, the galactic discs form gradually formed due to slow gas input or with other galaxies. However, the large wheel turned into large sizes, maintaining the spiral shape.

Scientists argue that this is possible thanks to a unique environment: the galaxy is located in the densely populated area of ​​the cosmos, where galaxies are ten times closer than the average in the universe. This created ideal conditions for soft merger and rapid growth.

The detection of a large wheel questions the modern theories of the evolution of galaxies. Astronomers believe that in the future, this galaxy can turn into one of the largest structures similar to what they are observed in nearby clusters such as a virgin cluster. However, more observation will be required using the James Webb telescope to clarify the formation models of galaxies.

The discovery emphasizes that the early universe is more complex and dynamic than previously expected.
