Scientists are preparing the most detailed map of the universe. In this, astrophysicists have revealed the details of the first 7.5 million galaxies out of 35 million. The Dark Energy Spectroscopic Instrument (DESI) has completed its first seven months of a survey that is expected to take five years to complete. This map is being prepared by a team of scientists led by the US Department of Energy’s Lawrence Berkeley National Laboratory in California.
Scientists are using surveys to generate detailed 3D maps that will help explain dark energy. More than 7.5 million galaxies have been cataloged so far. Its goal is to show the universe’s 35 million galaxies. The aim of this project is to shine a light on the mysterious dark energy. This force makes up 68 percent of the universe and is accelerating its expansion.
The secrets of the past and future of the universe will be revealed
The map will help astronomers understand how the universe began and where it is headed next. At the same time, it will also be possible to find out whether the universe will always be expanding or what can be its future? Project scientist Dr Julian Guy said the team was looking at patterns and structures throughout the universe through the new map. He said that galaxies are the largest structures in the universe.
Scientists doing CT-scanning of the entire universe
Durham University professor Carlos Franck, who was involved in the project, said that despite being at an early stage, scientists are already able to make new discoveries. He explained that DESI is making new achievements in producing this map of the universe that is the most detailed ever. This will help us find clues about the nature of dark energy. If this map is called a CT scan of the entire universe, then it will not be an exaggeration.
DESI made of 5,000 automatic mini telescopes
Astronomers believe that dark energy, which makes up about 68 percent of the known universe, is resisting the pull of gravity and preventing contraction. To confirm this, and to understand the phenomenon of dark energy, the team has created DESI. Which is made up of 5,000 automated mini telescopes, each of which images a new galaxy every 20 minutes.
