While scientists discovered the Cosmic Vine using the James Webb Space Telescope, they have yet to find a string of galaxies ...

A new study has found that a hidden bias in galaxy models can skew gravitational-wave measurements of how fast the universe is expanding. That finding complicates one of astronomy’s most promising ...

Where are the smallest galaxies? A recent study suggests that there may not be as nearly as many of them in the early universe as there should be, which has big implications for the story of how our ...

Study reveals that the Euclid telescope may be underestimating the number of barred galaxies due to limitations in its images ...

How fast can a galaxy build ordered magnetic fields spanning thousands of light-years? Existing theories say several billion ...

Still in its original galaxy, a rare holdout from the second generation of stars sheds new light on the origins of the ...

Understanding how galaxies grow has long stood as one of astronomy’s core challenges. Over time, scientists have gathered evidence that galaxy mergers matter. When two galaxies move close, gravity can ...

A developing galaxy cluster dating to about 1 billion years after the Big Bang is shown in this handout image released on January 28, 2026. The white box marks the field of view of the Chandra X-ray ...

A galaxy in the early universe was rich with oxygen, astronomers have found. The discovery raises questions about how early ...

Two new studies have measured the expansion of the universe in our immediate cosmic neighborhood using a novel method that ...

The James Webb Space Telescope has revolutionized astronomy in just two years of operations, but how can it see a galaxy 33.8 billion light-years away in a universe that is only 13.8 billion years old ...
