Astronomers discover a galaxy 12 billion light-years away, similar to the Milky Way


Astronomers have discovered a distant galaxy that is surprisingly similar to our own, the Milky Way, and they say it looks like a near-perfect light ring in space, and astronomers from the Max Planck Institute used a telescope. Atacama Large Millimeter / submillimeter Array (ALMA) In Chile to find the galaxy 12 billion light years away from Earth.

According to the British “Daily Mail” website, the galaxy is so far away that it took more than 12 billion years for its light to reach us, and it was named SPT0418-47 They are surprisingly different, and contradict the theories that claimed that all galaxies in the early universe were turbulent and unstable, according to astronomers.

The finding shows that the structures in our Milky Way and other spiral galaxies were already around 12 billion years ago when the universe was young, the researchers say.

While the galaxy studied by astronomers does not appear to have spiral arms, it does have at least two features defining our Milky Way galaxy – the bulge of the rotating disk, and the bulge is the large group of stars tightly packed around the center of spiral galaxies – seen as a white point in a galaxy. Milky Way.

This is the first time a bulge has been seen early in the history of the universe, making SPT0418-47 The most distant form of the Milky Way.

“The biggest surprise was to find that this galaxy looks just like nearby galaxies, contrary to all expectations from earlier models and less detailed observations,” says co-author Filippo Fratternale.

The astronomer from the University of Groningen in the Netherlands said that small galaxies in the early universe were still in the making, and this led researchers to expect them to be chaotic and lack the characteristic structures typical of more mature galaxies like the Milky Way.

The study of distant galaxies is like SPT0418-47 It is fundamental to our understanding of how galaxies form and evolve, as this galaxy is so far away that we see it when the universe was only 10 percent of its current age because it took 12 billion years for its light to reach Earth.

By studying the galaxy, we go back to a time when these small galaxies were just starting to evolve, according to the research team.

Since these galaxies are so far away, detailed observations with even the most powerful telescopes are nearly impossible as the galaxies appear small and dim, but the team overcame this obstacle by using a nearby galaxy as a powerful magnifying glass – an effect known as a gravitational lensing.
