Dozens of dwarf galaxies swarming around the Andromeda Galaxy like bees have been caught on camera by the Hubble Space ...

The "deaths" of galaxies are caused by their central supermassive black holes, and the "smoking gun" evidence of this connection takes an unexpected form.

Developed by Israeli scientist Mordehai Milgrom in the 1980s, MOND postulates that galaxies form and expand much quicker under a stronger force of gravity than the standard model accounts for. The ...

Unusually fast-moving gas clouds near a nearby galaxy suggest they may have come from outside the galaxy. Scientists have ...

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." Skip to main content.

Galaxies have an overall internal motion called disk velocity. It’s how gas, dust, and stars move around the galactic center.

The team gathered images of 850 galaxies with JWST, and classified them into the typical galaxy shapes: disks (like our own spiral galaxy), clumps, irregulars, or some combination of the three.

Galaxies like the Milky Way boast more than spirals; they also have feathers, where clumps of new stars are born. Astronomers have been stumped by how these complex structures form, but now a ...

Most galaxies that enter the "urban centers" of clusters, Rudnick added, do so along cosmic web "superhighways," with a small number taking "rural routes" that bring them into the clusters and ...
