FAST detects coherent interstellar magnetic field with a technique conceived at Arecibo
Magnetic fields are the essential, but often "secret" ingredients of the interstellar medium and the process of making stars. The secrecy shrouding interstellar magnetic fields can be attributed to the lack of experimental probes. While Michael Faraday was already probing the link between magnetism and electricity with coils in the early 19th century in the basement of the Royal Institutio
