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 collaboration with the US' Georgia Institute of Technology, researchers from Maynooth University in Ireland have unveiled a new computer simulation that mirrors early universe conditions, ...

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 ...

Using data from the James Webb Space Telescope, astronomers traced how Milky Way–like galaxies formed and changed over time.

Enabled by supercomputing, University of Pretoria (UP) researchers have led an international team of astronomers that has provided deeper insight into the entire life cycle (birth, growth and death) ...

Artist's conception of early starbursting galaxies. UC Davis astronomers collaborated on new simulations showing how bright galaxies could emerge early in the universe. Stars and galaxies are shown in ...

In between all the stars in our galaxy, there is a vast, diffuse mix of gas and dust known as the interstellar medium — and scientists have developed a new computer model to explore the magnetism and ...

The standard cosmology can answer almost nothing about how the structure of a galaxy is formed. It expects a supermassive black hole at the center and dark matter in the halo to explain the ...

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 ...

Astronomers have discovered a rare starless galaxy-like cloud known as a RELHIC, providing the strongest evidence yet for a cornerstone prediction of the Lambda CDM model: that many small dark matter ...

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 ...
