Smaller, because galaxies merge together and attract more matter over time, and Less spiral-like, because we are only seeing the brightest parts of the most active, star-forming galaxies.

To estimate distances, the team analyzed the objects' brightnesses across multiple wavelengths to infer redshift, age and ...

Two colliding galaxies have been found to be reorganizing their dwarf satellites, potentially solving a major conundrum ...

Galaxies, the grand entities of the universe, have fascinating and dynamic lives of their own. They form, evolve, and occasionally merge, creating stunning visual spectacles. Our very own galaxy, the ...

While the new James Webb Space Telescope has spotted even older galaxies during its first year of work, it's the size and maturity of these six apparent mega-galaxies that stun scientists.

Astronomers are detecting hundreds of galaxies that are almost devoid of stars. There are at least four theories on how they got that way.

If we can see at most 3% of the universe, how can we estimate the total number of galaxies in it?

When the James Webb Space Telescope first opened its golden mirrors in 2022, it delivered breathtaking views of the cosmos.
