ESA’s Euclid Mission to Reveal a 3D Map of the Universe

ESA's groundbreaking Euclid mission is set to craft a 3D map covering over a third of the sky.


In a significant stride towards understanding the universe, scientists from ESA’s Euclid mission have unleashed one of the most precise and exhaustive computer simulations ever. Launched on July 1, the Euclid mission is already returning images, embarking on an audacious endeavor to create a 3D map of the universe. These simulations are empowering researchers to fathom the enigmas of dark matter and dark energy, representing a time frame of 10 billion years in cosmic history.

Simulating the Universe: The Euclid Mission

Crafting a Comprehensive 3D Map

ESA’s groundbreaking Euclid mission is set to craft a 3D map covering over a third of the sky. Containing a plethora of data, this map is a unique representation that spans 10 billion years of cosmic events, providing insights into the properties and mysterious nature of dark energy and dark matter.

Tackling the Data Challenge

The sheer volume of data generated by Euclid’s observations presents a formidable task. Managing such an intricate and unprecedented set of novel information requires cutting-edge tools and techniques.


Preparing for Complexity: The Euclid Flagship Simulation

In preparation, the Euclid Consortium has developed the Euclid Flagship simulation, a highly sophisticated tool to handle the anticipated data complexity. Alongside this innovation, ESA has unveiled an explanatory video, offering a detailed view of this ambitious project.

Advanced Computational Modeling

Unique Laboratories for Universe Modeling

Utilizing large banks of sophisticated processors, these computer simulations have become a distinctive laboratory. They enable modeling the formation and evolution of extensive structures in the universe, including galaxies, galaxy clusters, and the interconnected cosmic web.

Tracking Dark Matter and Galaxy Formation

With state-of-the-art computational techniques, astrophysicists can monitor the movement and behavior of an immense number of dark matter particles across vast cosmic volumes. These simulations elucidate how galaxies form, evolve, and are distributed across the celestial sphere, under the influence of gravitational forces.



ESA’s Euclid mission, with its blend of innovation and technology, opens new frontiers in understanding our universe. By creating an unparalleled 3D map and employing intricate simulations, it stands poised to unravel the deepest cosmic mysteries. As we peer into the dark corners of space, we may soon find answers to questions that have long puzzled humanity.
