For the first time, a group of cosmologists say they’ve created virtual galaxies inside their computers without any dark matter. Critics of dark matter see it as a win for a controversial model of how ...

For years, astronomers have studied the formation of galaxies using computer simulations, but with limited success. The galaxies that formed in previous simulations were often too massive, too small, ...

Cosmology researchers are releasing initial findings from IllustrisTNG, their follow-up to the 2015 record-breaking Illustris simulation -- the largest-ever hydrological simulation of galaxy formation ...

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, ...

Artist conception of early starbursting galaxies. The image is rendered from FIRE simulation data used for this research that can explain recent JWST results. Stars and galaxies are shown in the ...

In new simulations, 'dark atoms' formed dark stars and could even trigger the formation of black holes. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it ...

Astrophysicists have been trying for nearly two decades to produce a model capable of simulating the genesis of a spiral galaxy — the class of flat, rotating disk galaxies to which our own Milky Way ...

The formation of galaxies is a complex dance between matter and energy, occurring on a stage of cosmic proportions and spanning billions of years. How the diversity of structured and dynamic galaxies ...

Joanna Thompson: This is Scientific American’s 60 second science. I’m Joanna Thompson. In 2018, a group of astronomers from Yale discovered something odd: two galaxies that had almost no dark matter.

New simulations show how thousands of galaxies evolve by traveling through the strands of gas, dust and stars that make up the universe's "cosmic web." When you purchase through links on our site, we ...

Take a look at a wide variety of galaxies in the Universe, and you'll find a vastly different set of stories. The largest ones are giant ellipticals, many of which haven't formed any new stars over ...
