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.
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.
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…
Searching for the first supernovae in the universe
Astronomers developed new theoretical models for how stars evolve that suggest the JWST could glimpse the oldest stars in the universe…
Intelligent life might be rare
How hard is it for evolution to produce intelligent life like humans? We don't really know, but some computational modelers tried to answer…
How stars can limit life in the universe
For the past few decades, scientists have been looking at planets outside of our solar system to see if they could host life. Now,…
Using The Big Bang As A Ruler
Baryon acoustic oscillations, an artifact remaining from the Big Bang, can be used by scientists to measure cosmological distances…
