HIGHLIGHTS

* The study makes use of the Dark Energy Spectroscopic Instrument (DESI).

* Every month, around a million galaxies are added to the project.

*The final results will stretch back 11 billion years.

The far more three dimensional map of the universe yet has been created by a multinational team of researchers, with cosmologists revealing details of the first 7.5 million galaxies out of 35 million. The breathtaking image depicts a cosmic web of galaxies that stretches back billions of light-years. And this is just the beginning of the project, which has been running for seven months. The survey will take five years to complete and will help explain dark energy, a factor that makes up 68 percent of the cosmos and drives its growth.

The Dark Energy Spectroscopic Instrument (DESI) is being used for the research, and a component made of 5,000 optical fibres has been created to extend the telescope's field of vision. Every month, around a million galaxies are added to the project. When the map is complete, with data dating back as far as 11 billion years, it is likely to aid scientists in their understanding of the universe's origins and future directions.

'This [research] will assist us in our search for information concerning deep power's origins. We'll probably know further about dark matter and its role in the formation of galaxies such as the Milky Way and the evolution of the universe.'

The data is also being used to figure out how medium-sized black holes in small galaxies behave, according to the researchers. DESI, which has now mapped 7.5 million galaxies, plans to add another 27.5 million by the end of its mission in 2026. DESI is documenting considerably fainter and redder objects than previously discovered, according to Victoria Fawcett, a PhD researcher at Durham University's Centre for Extragalactic Astronomy, which is also collaborating in the study. 'We're discovering a lot of strange systems, including huge samples of rare items that we will not be able to investigate in depth before,' she explained.

The Nicholas U. Mayall Telescope in Arizona has DESI installed.
