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

New observations from the James Webb Space Telescope show that ancient galaxies lived fast and died young because of intense, collision-driven winds.

An intense demolition derby of at least six galaxies smashing into one another has been found lurking in the early universe by the James Webb Space Telescope.

When studying local galaxy cluster Abell 3667, Anthony Englert GS, a Ph.D. candidate in physics, noticed something unique. Connecting the brightest galaxies in two small clusters within Abell 3667 was ...

The process of galaxy merging reshapes cosmic structure by driving dramatic changes in the distribution and state of interstellar gas, thereby governing the rates and locations of star formation.

Whether or not galaxies merge depends on how strong the gravitational attraction is between the galaxies and whether the universe’s expansion is more powerful than gravity. Gravity affects everything ...

Galaxies like the Milky Way grow by merging with smaller galaxies over billions of years, unlike dwarf galaxies, which have long been thought to lack the heft to attract mass and grow in the same way.

All massive galaxies are believed to host supermassive black holes millions or billions of times the mass of the Sun. When galaxies merge — which we know they do, and frequently — it seems a foregone ...

(THE CONVERSATION) Billions of light years away in a remote part of the universe, two neutron stars – the ultradense remnants of dead stars – collided. The catastropic cosmic event sent light and ...
