Dark matter influences the size of galaxies
Researchers simulated the effects of dark matter halos on galaxies and found that denser halos produced smaller galaxies.

Characterizing galaxies at “cosmic noon”
Astronomers studied 3 galaxies that formed 2 to 3 billion years after the Big Bang to calculate how much gas, stars, and dark matter they…
JWST reveals properties of dusty star-forming galaxies
Astronomers used new JWST data to unravel the structures of 22 dusty star-forming galaxies that previous telescopes couldn’t see.
Astronomers model early star clusters
Scientists used computer simulations to determine how ancient star clusters formed. Their results were similar to real clusters found with…
How did early galaxies form?
Astronomers observed a distant, ancient galaxy and found that it consisted of 5 distinct regions, suggesting a complex formation history…
How do small galaxies get magnetic fields?
Astronomers showed that small galaxies orbiting larger galaxies become 2 to 8 times more magnetic after nearing their hosts.
Where do deep-space gamma-rays come from?
Researchers found that distant star-forming galaxies can only account for about half of the high-energy radiation from outside the Milky Way…
Galactic clusters impact star formation
Researchers used light emissions to reconstruct the evolution of galaxies that fall into clusters in deep space.
Scientists date star columns at the center of galaxies
Researchers used data from the Very Large Telescope in Chile to study dense columns of stars at the center of 20 nearby galaxies. They found…
Astronomers find distant galaxies with neural networks
Researchers developed a computer algorithm that correctly predicted the light emission characteristics of ancient faraway galaxies based on…
