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 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 ...

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

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, ...

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 ...

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 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 ...

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 ...

Ultramassive black holes (UMBHs), observed to be tens of billions of times the Sun's mass, pose a theoretical challenge regarding their rapid formation early in the universe. A proposed hypothesis, ...

Just as the sun has planets and the planets have moons, our galaxy has satellite galaxies, and some of those might have smaller satellite galaxies of their own. To wit, the Large Magellanic Cloud (LMC ...
