How have magnetic fields in galaxy clusters evolved throughout cosmic history, and what can these fields tell us about magnetism in the early Universe? Thanks to a few tricks from radio astronomy, today’s authors have some answers.
How do neutron stars acquire such strong magnetic fields? Why do these fields differ between pulsars and magnetars? Today’s paper suggests that *convective dynamos* may be at play.
The Solar Cycle sees our Sun alternate between phases of tempest and tranquility driven by its magnetic field roughly every 11 years. It has been difficult to measure the magnetic strength when the Sun goes silent – until now.
Magnetism is an important but often neglected mechanism in the study of exoplanets, but how does it affect their atmospheres? Check out today’s paper to find out!
Cosmic magnetic fields are everywhere, but we don’t know where they came from. Today’s paper looks at simulations of the earliest fields in the Universe to try to solve this magnetic mystery.
In the heart of the barred spiral galaxy NGC 1097, there’s more to the magnetic field than meets the eye.
