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 ...

New simulations of Milky Way-like galaxies reveal that the strange split between two chemically distinct groups of stars may ...

New simulations reveal that the Milky Way’s odd split between two chemically distinct groups of stars isn’t a universal ...

The stars in our galaxy exhibit a curious chemical division, but is this the norm in the Universe? A recent study shows that ...

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.

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 ...

Razor-thin chain of 14 galaxies may be the biggest spinning structure yet ...

The discovery reinforces established theories about space. There could be many more satellite galaxies orbiting the Milky Way than previously thought or observed, according to astronomers. As many as ...

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, ...

From your place inside the Milky Way, you are living within a galaxy that keeps a detailed chemical diary. Every star holds ...
