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 ...

Astronomers spotted nine galaxies with characteristics that have never been seen as a collection before. It's possible this ...

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.

Astronomers have completed the most comprehensive census of active galactic nuclei (AGN) to date, providing the clearest ...

New paper led by UC Santa Cruz undergraduate suggests that long-dormant galaxies deemed to be dead may actually be stunted by ...

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

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

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 ...

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 ...
