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 ...

Webb reveals a bridge of stars linking two nearby dwarf galaxies, offering a look at how gravity reshapes galaxies and sparks ...

An international team of astronomers has uncovered multiple evolutionary paths for the universe's most massive galaxies. Observations of ultramassive galaxies, each containing more than 100 billion ...

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.

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 ...

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

Professor Woong-bae Zee of the College of Liberal Studies at Sejong University has revealed that a galaxy does not possess only a single evolutionary pathway; instead, depending on the nature of its ...

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, ...
