Scientists have discovered a clone of the milky Way galaxy “in the Bud”

Ученые обнаружили клон галактики Млечный Путь «в зародыше»

Another sensational discovery.

Astronomers use telescopes of the group of “Large lattice of millimeter range” (ALMA) in Northern Chile, were able to see the distant galaxy, which is very similar to our milky Way at the stage of nucleation. Although the galaxy has no spiral arms like our galaxy, it has a rotating disc and a cluster of stars that are grouped around the center – that’s what they looked like in the early stage of formation.

An array of the most expensive to operate ground-based telescopes allows you to see the most distant objects in the Universe. ALMA was able to catch the faint silhouette of a distant galaxy SPT0418-47. According to astronomers, the light from SPT0418-47 traveled more than 12 billion years to reach Earth. This means we see the galaxy now as it was 12 billion years ago, or just 1.4 billion years after the Big Bang.

Even with the most powerful optical telescopes, mankind has, it is almost impossible to see these distant galaxies “live” because they look small and dull. To circumvent this limitation, a team of scientists used a galaxy as a “magnifying glass” due to an effect called gravitational lensing. Using this technique the gravitational pull of a nearby galaxy distorts and deflects light from a distant galaxy, causing it to appear enlarged.

Galaxy is also surprisingly stable, which contradicts the theories that almost all of these objects were fragile and sparse in the early years of the Universe. Study co-author from the max Planck Institute of astrophysics Simon Vegetti, commented that the results were “quite unexpected and has important implications for understanding the evolution of galaxies”.
