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 ...

A recent paper reveals we're almost certainly going to collide with a galaxy in the next couple billion years, but it's not the one we thought. Reading time 2 minutes For over a decade, researchers ...

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 ...

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 ...

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 ...

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 ...

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 ...
