How this cosmic map of magnetic fields could help illuminate one of the universe’s most mysterious forces
Scientists led by Australia's CSIRO have created the largest map of magnetic fields in the universe by analyzing light from nearly 4 million galaxies. This data aims to help researchers understand the origins and evolution of magnetic forces since the Big Bang.
Why it matters
Mapping these fields provides fundamental insights into the physics of the universe and the evolution of galaxies over cosmic time.
