Although magnetic forces are usually much weaker than gravity in shaping cosmic structures, the findings suggest that strong, ordered magnetic fields may have emerged earlier than expected. Over time, ...

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

A violent collision between two dwarf galaxies strips them of their dark matter.

Astronomers have long argued that dark matter is the invisible scaffolding that holds galaxies together. Without its immense ...

Spread the loveAstronomers have made a groundbreaking discovery, identifying a third galaxy that appears to be devoid of dark matter, a finding that lends significant credence to a theory suggesting ...

The oxygen in a galaxy does not sit still. It spreads, thins out, piles up, and leaves behind a record of where stars formed, where gas moved, and when smaller galaxies crashed in.

For the first time, scientists have reconstructed the full history of a galaxy outside the Milky Way using chemical clues. By ...

Astronomers have made impressive progress on that question by piecing together the biography of a galaxy very far outside our ...

The standard model for how galaxies formed in the early universe predicted that the James Webb Space Telescope (JWST) would see dim signals from small, primitive galaxies. But data are not confirming ...

Through the SPS summer internship program, physics undergraduates like MJ Keller are placed in organizations where they apply ...

This NASA/ESA Hubble Space Telescope image features a galaxy whose asymmetric appearance may be the result of a galactic tug of war. Located 35 million light-years away in the constellation Leo, the ...
