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

Magnetic fields that stretch across thousands of light-years should take a very long time to organize. Standard dynamo theory ...

A team of astronomers has reconstructed the 12-billion-year evolutionary history of a giant spiral galaxy, marking a major step toward understanding how galaxies like our own Milky Way formed. The ...

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

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

Add Yahoo as a preferred source to see more of our stories on Google. When astronomers look deep into the early universe, they don’t expect to see fully developed cosmic objects but small galaxies, ...

A team of astronomers led by the Center for Astrophysics | Harvard and Smithsonian have for the first time used galactic ...

A blazing supermassive black hole can influence far more than its own galaxy. Scientists found that quasars emit radiation strong enough to shut down star formation in nearby galaxies millions of ...
