Astrophysicists Release Massive Universe Simulation Accessible to Public

• May 6, 2026

An international group of astrophysicists has opened public access to one of the most extensive simulations of the universe ever created. Leading the effort is the team from Leiden University in the Netherlands, who have compiled an enormous dataset capturing the evolution of matter from the Big Bang to the formation of the present-day cosmic web.

Unprecedented Scale and Detail in Cosmic Simulation

The project, known as FLAMINGO, encompasses over 2.5 petabytes of data—equivalent to the size of roughly 500,000 high-definition movies. This massive volume of information provides unparalleled detail into the processes shaping the universe’s structure over billions of years.

By tracing cosmic evolution at this scale, the simulation offers scientists and researchers around the world a valuable resource for studying the formation and distribution of galaxies, dark matter, and large-scale cosmic phenomena. The release of such a comprehensive dataset in the public domain marks a significant step forward for collaborative scientific investigation.

The data, made available through the Netherlands Research School for Astronomy (NOVA), allows for broad access beyond the core research team, encouraging further advancements in both astrophysics and computational modeling techniques. This openness aims to accelerate discoveries and deepen understanding of the universe’s fundamental properties.

As cosmological research moves toward increasingly sophisticated models, FLAMINGO’s public release represents a milestone in leveraging big data and simulation technology for space science. The dataset’s enormous size and scope reflect both the complexity of the universe and the expanding capabilities of modern computational resources.

With the availability of this simulation, scientific institutions and individuals interested in cosmic evolution now have a groundbreaking tool for exploring the universe’s origins and large-scale dynamics from the dawn of time to the present cosmic web.

Researchers unveil one of the largest universe simulations ever, offering public access to 2.5 petabytes of cosmic evolution data.
