The US Department of Energy’s Lawrence Berkeley National Laboratory in California has revealed the creation of the most detailed 3D map of the universe in five years.

Whatsapp The British Daily Mail, The most detailed 3D map of the universe is currently being created, as astrophysicists have revealed details of the first 7.5 million galaxies out of the 35 million, as the dark energy spectroscopy instrument “DESI” has completed the first seven months of the survey, which is expected to take a total of five years.

An international collaboration of scientists, led by the US Department of Energy’s Lawrence Berkeley National Laboratory in California, is using the survey to create a “tremendously detailed 3D map” that should help explain dark energy.

The goal of the project is to shed light on the mysterious dark energy, the force that makes up 68% of the universe and is accelerating its expansion, as owning the map will allow astronomers to understand how the universe began, and where it is heading next, whether it will expand forever, or collapse , or separates.

Project scientist Dr. Julian Gay, from the University of California – Berkeley, said that the team was seeing patterns and structures throughout the universe through the new map, as it appeared in the distribution of galaxies within the three-dimensional map, huge groups, filaments and voids, which are the largest structures in the universe: But within them, you find an imprint of the very early universe, and the history of its expansion since then.”

Professor Carlos Frink, from Durham University, who is also involved in the project, said that although it is in its early stages, scientists are already beginning to break new ground.

“DESI, made up of 5,000 small robotic telescopes, each of which image a new galaxy every 20 minutes, really breaks new ground in producing this map of the universe which is the most detailed map we’ve ever seen,” he explained.

Astronomers believe that dark energy, which makes up about 68 percent of the known universe, resists gravitational pull and stops contraction, and the DESI data will go back 11 billion years, to reveal evidence about the evolution of not only galaxies, but quasars, which are the brightest objects in the universe. .
