Astronomers Have Mapped the Milky Way's Magnetic Fields in 3D

Researchers have developed the first 3D maps of magnetic field structures within a spiral arm of the Milky Way. While we've seen smaller-scale magnetic fields before, this is much larger, showing the overall magnetic pattern in our galaxy. These fields are incredibly weak, about 100,000 times weaker than the Earth's magnetic field, but they impact the galaxy, strongly influencing star-forming regions.
