**Summary:**
The Euclid Consortium, managing the European Space Agency’s Euclid telescope, has created Flagship 2, the most extensive simulation of the universe to date. This simulation, mapping 3.4 billion galaxies and tracking 4 trillion particles, is crucial for analyzing data from Euclid, which is mapping the distribution of dark energy and dark matter. While based on the standard cosmological model, the simulation and Euclid’s observations are designed to challenge this model, especially regarding the nature of dark energy. Researchers anticipate the observations will reveal potential “cracks” in our current understanding of the universe.

**Euclid Telescope Team Creates Massive Universe Simulation to Hunt for Dark Energy Secrets**
**Zurich, Switzerland** – As the European Space Agency’s Euclid space telescope continues its mission to map billions of galaxies, the team behind the project has unveiled “Flagship 2,” the most detailed simulation of the universe ever created. The simulation, spearheaded by astrophysicist Joachim Stadel of the University of Zurich (UZH), maps an astounding 3.4 billion galaxies and traces the gravitational interactions of over 4 trillion particles.
The sheer scale of Euclid’s data output requires sophisticated tools for analysis. Julian Adamek, another astrophysicist at UZH involved in the project, explained that simulations like Flagship 2 are essential for speeding up processing times and ensuring accurate interpretation of the telescope’s findings.
Since 2023, Euclid has been scanning approximately one-third of the night sky, gathering data on the distribution of dark energy and dark matter, the mysterious substances that make up the vast majority of the universe. By peering up to 10 billion years into the past, Euclid aims to shed light on the expansion of the universe and the properties of dark energy.
While Flagship 2 is based on the current “standard cosmological model” – our best existing description of the universe – researchers are eager to see how Euclid’s observations might challenge that model.
“We already see indications of cracks in the standard model,” Stadel said. The team is particularly focused on understanding dark energy, which, in the standard model, is treated as a constant force. Euclid’s data might reveal that dark energy’s properties have changed over time, potentially revolutionizing our understanding of cosmology.
Euclid’s first observational data was released in March 2024, with the next publication of datasets scheduled for Spring 2026. The mission promises to provide unprecedented insights into the fundamental nature of the universe, potentially unraveling some of its deepest mysteries.
