The FLAMINGO super simulation maps the universe from its earliest moments but finds galaxies cluster less than cosmological models predict, deepening a long-standing puzzle.

Animations show the evolution of density and flow in simulations of a planet embedded in the envelope of a giant star, showing the interactions of the inspiralling planet with the gas in its vicinity.

Astrophysicists have confirmed the accuracy of an analytical model that can unlock key information about supermassive black holes and the stars they engulf. At the center of most large galaxies lives ...

The world's most elaborate cosmological simulation of the evolution of our universe was recently completed by astrophysicists. For the first time, a hydrodynamic cosmological simulation is large ...
