Learn how galactic archaeology uses chemical clues to uncover how galaxies formed and evolved over billions of years.

By reading the chemical “fingerprints” of a distant galaxy, astronomers reconstructed its 12-billion-year evolution. This new ...

For the first time, scientists have reconstructed the full history of a galaxy outside the Milky Way using chemical clues. By analyzing oxygen across NGC 1365 and comparing it with simulations, they ...

A team of astronomers led by the Center for Astrophysics | Harvard and Smithsonian have for the first time used galactic archaeology, the study of detailed chemical fingerprints in deep space, to ...

Thanks to the natural magnification from gravitational lensing, researchers have been able to study a small galaxy from when the universe was not even 1 billion years old. They saw that it is made of ...

A nearby galaxy is behaving strangely—and now scientists know why. The Small Magellanic Cloud’s stars move in chaotic ...

T he first time I heard about galaxies without dark matter, I was sitting in my very first graduate class at the University of São Paulo. It was 2018, and the discovery had just ...

How fast can a galaxy build ordered magnetic fields spanning thousands of light-years? Existing theories say several billion years, but observations of galaxies in our universe imply shorter ...
