The classification has been in operation since November 2021 and it is expected that by its end it will have cataloged nearly 40 million galaxies found in outer space.
MEXICO CITY, Jan. 16 (RT).- A Collection international From Scientists found a job On the detail From Plus brilliant s Hinge a map From being in a three DimensionsWhich will allow astronomers to understand the role of dark energy in the origin and evolution of the universe, the institution responsible for the research said in a press release Thursday.
The project is managed by the Lawrence Berkeley National Laboratory of the US Department of Energy, and will last for five years, at the end of which it is expected to complete the map with information about 35 million galaxies, which will help in conducting various researches. in the field of cosmology and astrophysics.
Carlos Frink, a scientist at Durham University (UK), explained to the media daily Mail That although it is in the first stage, scientists are already beginning to break new ground, adding that “this will help us search for clues about the nature of dark energy, but we will also learn more about dark matter and the role it plays in the way galaxies like the Milky Way are formed.” and how it evolves in the universe.”

How will this map be completed?
In seven months, more than 7.5 million galaxies have been cataloged with the help of the Dark Energy Spectroscopic Instrument (DESI), a device that began construction in 2015 and made up of more than 5,000 robotic telescopes, each of which receives new galaxy images every 20 minutes. In addition to adding a million of them every month.
DESI is already breaking new ground by producing this map of the universe, the most detailed map we’ve ever seen, according to confirmed scientist Carlos Frink.
Installed at Kitt Peak National Observatory in Arizona, DESI has the ability to study more galaxies than other astronomical observation equipment in the world, because it uses the latest fiber-optic system that splits light into groups of color for celestial bodies found in space such as galaxies and stars with a precision of 10 microns.
“Ten microns is very small,” said Ohio State University scientist Klaus Hünscheid, who is responsible for the project’s hardware. He added that it is less thick than a human hair.
Know the colors of dark energy
The colors indicate the chemical composition of a celestial body, as well as information regarding the distance they have traveled and the speed at which they are traveling. “DESI is really cool because it detects things that are much fainter and redder” than previously discovered, said Victoria Fawcett, a doctoral student at Durham University.

The device can determine when the light from each galaxy travels to the red end of the visible electromagnetic spectrum due to the expansion of the universe during billions of years in which the light traveled before reaching the planet Earth, allowing the device to analyze the depth of the sky, in addition to knowing the distance of the galaxy, so that it can in The end draw a 3D map.
DESI has classified red shifts since November 2021 for 2.5 million galaxies.
