A new simulation released by NASA’s Ames Research Institute reveals a stunning vision of the evolution of a galaxy. Blue influx gases, white stars and red satellite galaxies are shown moving thousands ...

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.

Image: Snapshots of the time evolution of a collision of two spiral galaxies with black holes at their center from a computer simulation. Color indicates temperature and brightness the gas density.

A small group of young researchers at the Cosmic Dawn Center, Niels Bohr Institute, University of Copenhagen, have, through ...

After combing through NASA's James Webb Space Telescope's archive of sweeping extragalactic cosmic fields, a small team of ...

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 ...

The study of galaxies and their star formation processes remains a cornerstone of modern astrophysics. Galaxies are the fundamental building blocks of the Universe, each hosting a complex interplay of ...

Astronomers studying galaxy evolution have long struggled to understand what causes star formation to shut down in massive galaxies. Although many theories have been proposed to explain this process, ...

A new study shows how Milky Way chemical tracks emerge from shifting star formation and gas supply, reshaping ideas about the ...

How do you find a galaxy that never formed? The standard cosmological model predicts the existence of "failed" galaxies - clumps of dark matter that captured gas but never birthed a star. Because they ...
