Traveling over 13.4 billion years, the ALMA supertelescope system in Chile’s Atacama Desert has captured images of one of the oldest galaxies in the universe in radio light.
A study led by Nagoya University and the National Astronomical Observatory of Japan has measured the age of an extremely distant galaxy, recorded using radio signals via the network. ALMA radio telescope – one of the most efficient ground-based telescope systems in the world.
The existence of this galaxy had already been determined by the James Webb Space Telescope. Since it’s a spacecraft, James Webb has a wider field of view, but when it comes to looking specifically at a distant object under radio light, “The Eyes of God” of ALMA to promote its strengths.

Article published above Monthly Notices of the Royal Astronomical Society indicates that the galaxy is named GHZ2/GLASS-z12 It is older than any object that has ever been observed and dated before. The time ALMA captured it was during the Big Bang (13.8 billion years ago), just 367 million years ago.
Specifically, light takes a while to reach Earth’s devices, so an object 13.4 billion light years away like this galaxy also means that light must be created. So his image also took so many years to shift.
In other words, ALMA managed to peer into the past, to observe an ancient object when it was young, in the middle of a universe that is taking shape.
“The bright line emission shows that the galaxy rapidly enriched its gas reservoirs with elements heavier than hydrogen and helium. This gives us some clues about the formation and evolution of the first star systems, as well as their duration. – said co-author Jorge Zavala from the National Astronomical Observatory of Japan.
This particular discovery also provides many other interesting data about the world that has always been mysterious to humanity – the early universe – and which will also be studied by international research groups. “Special treatment”.
