Astronomers at Square Kilometre Array map the universe's magnetic web
Scientists at the Australia-hosted Square Kilometre Array have produced the largest map yet of the observable universe's magnetic web. The dataset opens new questions on the structure of cosmic magnetic fields.
ABC News AustraliaScientists at the Square Kilometre Array Observatory (SKAO) have published the most comprehensive map yet of the observable universe's magnetic web, ABC News Australia reports. The work is built from data collected by the Australia-based radio-telescope network and is the product of an international consortium.
The map shows how magnetic fields extend across galactic-cluster and filament scales. Researchers stressed that cosmic magnetic fields are a key variable for galaxy formation, plasma physics and high-energy particle dynamics. The data set has been opened to public use.
Experts say the findings are early-stage and that revising theoretical models on the origin of magnetic fields will take time. SKAO plans to extend the map in future observation cycles with higher resolution.
