Astronomers have released the FLAMINGO simulation of the universe that gives researchers a fresh way to test how the cosmos formed and evolved.

A Chinese-led international team has released the largest-ever cosmological simulation, named "HyperMillennium," offering scientists a powerful digital tool to explore cosmic evolution. This ...

Astronomers who simulate galaxies do not always get the same result, even when they start from identical conditions. New ...

In a feat of galactic archeology, astronomers are using ever more detailed information to trace the origin of our galaxy—and to learn about how other galaxies formed in the early stages of the ...

Galaxies are far more than the sum of their stars. Long before stars even formed, dark matter clumped up and drew regular matter together with its gravity, providing the invisible scaffolding upon ...

This animation shows the simulated evolution of a galaxy over 200 million years. While the simulations look very similar with and without the machine learning AI model, the AI model performed 4 times ...
