Researchers are creating the most detailed 3D map ever

An international team of scientists has produced the most detailed 3D map of the universe ever, with astrophysicists unveiling the details of the first 7.5 million galaxies out of 35 million. The stunning image shows the cosmic web of galaxies going back billions of light-years. And, this is only the beginning of the project, which is seven months Old. The survey, which will help explain dark energy, a force that makes up 68 percent of the universe and drives its expansion, is expected to take a total of five years to complete.

Scientists are using the Dark Energy Spectroscopic Instrument (DESI) for this project Made using 5,000 optical fibers a component that increases the telescope’s field of view. The project is connecting galaxies at a rate of about a million every month. When the map is complete, with data from 11 billion years ago, it is expected to help astronomers understand the origins of the universe and where it is headed.

“This [project] Will help us find clues about the nature of dark energy. We will also learn about the role of dark matter and galaxies like the Milky Way and its role in how the universe is evolving.”

Researchers are also using the data to gauge how medium-sized black holes behave in smaller galaxies. After mapping 7.5 million galaxies, DESI aims to add another 27.5 million by the end of its run in 2026.

Victoria Fawcett, PhD researcher at Durham University’s Center for Extragalactic Astronomy, who is also involved in the project, said DESI is cataloging much fainter and redder objects than previously discovered. “We’re discovering a lot of exotic systems, including large samples of rare objects, that we haven’t been able to study in detail before,” she said.
