Galaxies come in all different shapes and sizes, and a massive new simulation of the universe has captured that galactic variety with more accuracy than any simulation before it, according to a ...

Having developed a simulation which produces galaxies with characteristics similar to observed galaxies, astronomers can now study the evolution of individual galaxies in detail.

New simulations create galaxies without dark matter, overcoming a long-standing hurdle to MOND, a controversial theory that claims dark matter doesn’t exist.

Pictures are the key to new insights in the field of astrophysics. Such images include simulations of cosmic events, which ...

By strengthening the galactic winds in a computer simulation of the entire history of the universe, astronomers may have a more accurate model with which to study galaxies and their evolution.

Imagine looking at amazing space simulations all day long, on a massive computer. Stars exploding, galaxies forming, crashing together. And, this is part of your job!

A research team finds seven tiny dwarf galaxies stripped of their dark matter that nonetheless persisted despite the theft.

To perform the Eris simulation, the researchers began with a low-resolution simulation of dark matter evolving to form the halos that host present-day galaxies.

Galaxies’ spiral arms are responsible for scooping up gas to feed to their central supermassive black holes, according to a new high-powered simulation. Started at Northwestern University, the ...

Scientists at Harvard University and the Heidelberg Institute for Theoretical Studies have developed a method for simulating the evolution of the Universe that produces realistic galaxies.
