The invisible glue of the Milky Way

This video is available in Dutch only.

We earthlings know little about magnetic forces. Down here we experience gravity as a constant force that makes apples fall down and keeps our feet on the ground. But intergalactic magnetic fields are not at all constant. There are large and small scale fields, strong and weaker ones, strangely shaped clouds, slowly changing or very turbulent. Astrophysicist Marijke Haverkorn at the Radboud University in Nijmegen explores the magnetic forces in the Milky Way and studies their role in the intergalactic ecosystem.
