a team of astronomers has unveiled a revolutionary new approach to simulating the evolution of galaxies. Published in Monthly Notices of the Royal Astronomical Society, this breakthrough project, ...

Astronomers have observed a massive and extremely active barred spiral galaxy in the early Universe and found that it has important similarities and differences with modern galaxies. This improves our ...

Astronomers have revealed new details about how young stars shape their galactic surroundings in a new study. Researchers analyzed about 18,000 star-forming regions in nearby spiral galaxies using ...

New supercomputer simulations suggest the Milky Way could be surrounded by dozens more faint, undetected satellite galaxies—up to 100 more than we currently know. These elusive "orphan" galaxies have ...

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 ...

Observations of a galaxy from an early period of the Universe’s history reveal a bar-shaped structure and gas dynamics thought not to have been possible at that time. In broad brushstrokes, galaxies ...

Abstract : Weighing in at 1042 kilograms and measuring 1021 meters across, galaxies are perhaps the most awe-inspiring objects known to mankind. They are also the only places in an otherwise dark and ...

Secular evolution in disk galaxies describes the gradual restructuring of a stellar system driven by internal processes rather than external mergers or rapid interactions. Over cosmic time, ...

A research team led by Shuo Huang (NAOJ and Nagoya University) has observed a massive and extremely active barred spiral galaxy in the early universe with ALMA and the James Webb Space Telescope. They ...
