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, ...

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, ...

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 ...

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 ...

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 ...

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 ...

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 ...

To investigate whether the depletion times in dwarf galaxies, which are longer than those for Milky-Way-like galaxies by more than an order of magnitude 14,15, are set by the momentum injection from ...

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, ...
