Universe's Magnetic Secrets Mapped
4 Jun
Summary
- A vast cosmic map of magnetic fields has been created.
- Light from nearly 4 million galaxies was used for the map.
- The map helps investigate fundamental questions about the universe.
A groundbreaking cosmic map of magnetic fields, the most extensive ever produced, has been developed by an international team led by Australia's CSIRO. This remarkable chart, named SPICE_RACS, was constructed by analyzing the light from nearly 4 million galaxies as it traversed intergalactic space.
The map's creation was made possible by the Australian Square Kilometre Array Pathfinder radio telescope in Western Australia. Researchers can now investigate fundamental questions regarding the universe's physics and the origins of magnetic fields, which remain largely unknown since the Big Bang.
This detailed dataset, five times larger than previous efforts, has been shared globally with scientists. It promises to unlock new discoveries as researchers study specific star-forming regions and galaxies in the years ahead, shedding light on the universe's magnetic structures.
