Scientists have used a synthetic universe to observe how the first galaxies evolved and grew.

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 study of 300,000 galaxies confirms that gravity follows Newton's law and deepens the mystery of dark matter.

The Dark Energy Spectroscopic Instrument (DESI) has successfully completed the largest high-resolution 3D map of the universe ...

A team of astronomers looking at galaxies in the universe’s distant past have discovered nine young, compact galaxies, each weighing in at 200 billion times the mass of the Sun. Imagine receiving an ...

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 ...

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 ...

Whether the universe will “end” at all is not certain, but all evidence suggests it will continue being humanity’s cosmic home for a very, very long time. Our understanding of the future of the ...
