In a groundbreaking development for astronomy and space exploration, the European Space Agency (ESA) has unveiled the first section of a massive 3D map of the universe. This unprecedented map is being created through images captured by the Euclid telescope, which was launched in 2023.
The map represents just the beginning of what promises to be a comprehensive survey of the cosmos, revealing an astonishing array of galaxies, stars, and other celestial phenomena. Over the course of six years, Euclid aims to create the largest and most detailed 3D map of the universe ever made.
The Euclid Mission and Its Monumental Ambitions
The Euclid mission is a flagship project of the European Space Agency, with the primary goal of exploring the dark universe—specifically, the nature of dark matter and dark energy. These two phenomena make up approximately 95% of the universe, yet remain largely mysterious to scientists.
Euclid is designed to map the distribution of galaxies across a significant portion of the sky, helping researchers understand how dark matter and dark energy influence the structure and expansion of the universe.
The recently revealed first section of the map is a small, yet incredibly detailed, piece of what Euclid will ultimately capture. It covers just 1% of the total area that the telescope is expected to survey over the course of its mission.

This initial image, however, is already breathtaking in scope. It shows more than 14 million galaxies and tens of millions of stars, offering a glimpse into the immense scale and complexity of the universe. The final map is expected to include billions of galaxies and cover about one-third of the sky, making it the largest 3D map ever constructed.

Euclid’s 3D map will allow astronomers to measure the positions and distances of galaxies with unprecedented precision, creating a comprehensive picture of the universe’s large-scale structure. By doing so, scientists hope to unravel the mysteries of cosmic acceleration and gain insights into the fundamental forces shaping our cosmos.
Capturing the Gigantic Map of Universe in Unprecedented Detail
One of the most remarkable aspects of the Euclid telescope is its ability to capture images in incredible detail. To put this into perspective, a high-end smartphone camera typically produces images with around 12 million pixels.
The map created by Euclid, on the other hand, is a staggering 208 gigapixels—equivalent to 208 billion pixels. This immense resolution allows the telescope to detect even the faintest celestial objects, including distant galaxies and stars that would otherwise remain invisible.
The level of detail captured by Euclid is not only impressive but also crucial for its scientific goals. By mapping galaxies and other objects with such precision, the telescope can track how these objects move and evolve over time.
This data will help scientists better understand the role that dark matter plays in the formation and evolution of galaxies, as well as how dark energy drives the accelerated expansion of the universe.
One of the surprising discoveries from the first section of the map is the presence of faint cirrus clouds within the Milky Way galaxy. These clouds, which consist of interstellar dust and gas, are illuminated by stars and are difficult to detect with traditional telescopes. However, Euclid’s high-resolution images reveal these clouds in unprecedented clarity, allowing astronomers to study them in greater detail than ever before.
Professor Mat Page, a researcher at University College London’s Mullard Space Science Laboratory, expressed his excitement about Euclid’s capabilities: “Before Euclid, we would never be able to see the faint cirrus clouds in the Milky Way, and pick out every star that’s illuminating them in super-high resolution.”
This newfound ability to observe such subtle details opens up new avenues of research into the structure and dynamics of our galaxy, as well as other galaxies in the universe.
A Vision for the Future: Completing the Gigantic Map
While the first piece of Euclid’s map is already a significant achievement, it represents only a fraction of what is yet to come. Over the course of the six-year mission, Euclid will continue to capture images of the universe, gradually building up the largest and most detailed 3D map in history.
By the time the mission is complete, the map will cover approximately one-third of the sky, revealing billions of galaxies and countless stars, nebulae, and other cosmic structures.
Despite the incredible progress made so far, the Euclid mission is still in its early stages. The initial section of the map, which was revealed after just two weeks of observations, covers an area 500 times larger than the full Moon as seen from Earth. This rapid progress is a testament to the power and efficiency of the Euclid telescope, which is capable of surveying vast portions of the sky in a relatively short amount of time.
As Euclid continues its mission, scientists expect to make numerous groundbreaking discoveries. The detailed 3D map will not only provide new insights into dark matter and dark energy but also help researchers answer other fundamental questions about the universe.
For example, the map will allow astronomers to study how galaxies are distributed across the cosmos and how they interact with one another. It will also provide new information about the formation and evolution of large-scale cosmic structures, such as galaxy clusters and superclusters.
One of the most exciting aspects of the Euclid mission is its potential to uncover previously unknown phenomena. With its unprecedented level of detail, the 3D map could reveal hidden features of the universe that have never been observed before.
This could include new types of galaxies, mysterious cosmic objects, or even signs of new physical laws that govern the behavior of matter and energy on a cosmic scale.
The Euclid mission is also expected to complement other astronomical surveys, such as those conducted by the James Webb Space Telescope and the Vera C. Rubin Observatory.
By combining data from multiple observatories, scientists will be able to create a more complete and accurate picture of the universe, advancing our understanding of the cosmos in ways that were previously unimaginable.
The first piece of the gigantic 3D map of the universe created by Euclid marks the beginning of a new era in cosmic exploration. With its ability to capture images in incredible detail and survey vast portions of the sky, Euclid is poised to make groundbreaking discoveries about the nature of dark matter, dark energy, and the large-scale structure of the universe.
The map, once completed, will be the largest and most detailed 3D representation of the cosmos ever created, offering scientists an unparalleled tool for studying the universe and its many mysteries.
As the Euclid mission continues, astronomers and researchers eagerly await the wealth of new data that will be collected. With each new image, we come closer to unlocking the secrets of the dark universe and gaining a deeper understanding of the forces that shape our cosmos.
The journey to map the universe is just beginning, and the discoveries that lie ahead promise to reshape our understanding of the universe and our place within it.
