Mapping the Milky Way’s magnetic fields

Astronomers have used 41,000 individual measurements to map the magnetic fields of our galaxy in greater detail than ever before.

The map shows scientists a quantity known as Faraday depth, a concept that depends on magnetic fields along a specific line of sight.

Scientists have long been puzzled by the origin of the Milky Way’s magnetic fields, and the new map will help shed light on this mystery.
