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

Researchers studying a distant spiral galaxy have found that large-scale, ordered magnetic fields existed far earlier in cosmic history than standard theories predicted, forcing a fresh look at how ...

Astronomers have uncovered a hidden cosmic web of galaxies and gas by mapping hydrogen light from the early universe.

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

Astronomers have created the largest and most detailed 3D map yet of a glowing signal from the early universe, revealing hidden galaxies and gas from 9-11 billion years ago. By analyzing faint ...

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 ...

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 ...

The Small Magellanic Cloud (SMC) is one of the Milky Way's closest galactic neighbors—a small, gas-rich galaxy visible to the ...

A rare star reveals how the Universe's first stars exploded, helping explain the Milky Way’s outer halo and its unusual chemistry.

Still in its original galaxy, a rare holdout from the second generation of stars sheds new light on the origins of the elements—and how massive supernovae reshaped the cosmos ...
