Scale in the universe is hard to understand from a purely human perspective. Many times, the math just doesn't sit well with ...

A massive hole in the starlight at the center of a giant galaxy may be the scar left behind by two colliding supermassive ...

The James Webb Space Telescope has identified an extraordinary system of five galaxies merging when the universe was only about 800 million years old, according to a study published in Nature ...

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 ...

Galaxy mergers are fundamental events in the hierarchical assembly of structure, in which two or more gravitationally bound systems coalesce to form a single, more massive galaxy. Such interactions ...

Galaxies are far more than the sum of their stars. Long before stars even formed, dark matter clumped up and drew regular matter together with its gravity, providing the invisible scaffolding upon ...

Active Galactic Nuclei (AGN) mark the energetic cores of galaxies where accretion onto supermassive black holes releases prodigious luminosities across the spectrum. These nuclei can exhibit ...

The collision and merger of two neutron stars—the incredibly dense remnants of collapsed stars—are some of the most energetic events in the universe, producing a variety of signals that can be ...
