How this cosmic map of magnetic fields could help illuminate one of the universe’s most mysterious forces

Scientists have created the most comprehensive cosmic map of magnetic fields ever, charting the magnetic forces from nearly 4 million galaxies. This groundbreaking effort, led by Australia's CSIRO, could unlock secrets about one of the universe’s most elusive forces. Understanding these magnetic fields is crucial because they play a significant role in the structure and evolution of the cosmos, potentially shedding light on dark matter and dark energy. This discovery promises to advance our comprehension of the universe’s fundamental workings.
