Magnetism Frozen in Time.

A recent study reveals that magnetic properties of a red giant (shown here in comparison to the Sun) may survive the death of the star (Credit : ESO)

Every star you’ve ever looked at is hiding a magnetic secret and it may have been hiding it since birth. A new theoretical study has connected, for the first time, the magnetic fields detected deep inside dying red giants with the magnetism found at the surfaces of their long dead remnants. These fields may be ancient fossils, born early in a star’s life and surviving billions of years of violent transformation completely intact.
