Quasars stripped early galaxies of their gas, the basic raw material for making stars.

James Webb Space Telescope data has allowed researchers to map the cosmic web in the greatest detail ever achieved.

It pulled in gas and small companion galaxies, slowly building up the bright central region and sweeping spiral arms we see today. In a new study published in March 2026, my colleagues and I used this ...

The study challenges assumptions that galaxies are too vast to be affected by small changes.

Astronomers at the University of California, Riverside announced on May 11 that they have produced the most detailed map of ...

This animation shows the simulated evolution of a galaxy over 200 million years. While the simulations look very similar with and without the machine learning AI model, the AI model performed 4 times ...

Cosmologists may have to rethink galaxy evolution theories as more mature and orderly galaxies are found in the early universe. Credit: NASA / ESA / CSA / Joseph Olmsted (STScI) illustration Imagine ...

The Milky Way galaxy grew into its current form with the help of smaller galaxies over time, which it has "consumed" or merged with. Astronomers are able to pick out which stars in the Milky Way came ...

Scientists found one of the earliest known slow-spinning galaxies, challenging long-standing ideas about how massive galaxies ...

A team has revealed new insights into the motion of massive stars in the Small Magellanic Cloud (SMC), a small galaxy neighboring the Milky Way. Their findings suggest that the gravitational pull of ...
