An international team led by Australia's national science agency, CSIRO, has unveiled the SPICE-RACS map, the largest magnetic map of the universe ever created. Utilizing data from the Square Kilometre Array (SKA) telescope in Western Australia, this map is five times larger than all previous magnetic maps combined. It provides insights into the material between stars and distant galaxies, addressing questions about the universe's evolution over billions of years. The map was generated by measuring light twists caused by magnetic fields across nearly four million galaxies. According to SKAO Lead researcher Alec Thomson, this advancement opens new avenues for research previously thought impossible. CSIRO astronomer Tim Galvin emphasized the importance of making this data freely available to support ongoing scientific exploration. The Square Kilometre Array Observatory is also developing additional telescopes to enhance future cosmic studies.
