Earth's magnetic field seems steady and true -- reliable enough to navigate by.

As Earth warms, much of the extra heat is stored in the planet's ocean -- but monitoring the magnitude of that heat content is a difficult task.

New work from Carnegie's Peter Driscoll suggests Earth's ancient magnetic field was significantly different than the present day field, originating from several poles rather than the familiar two. It is published in Geophysical Research Letters.

A rocket was launched on Sunday 13 December 2015 to study the Earth's magnetic field above Norway.

European Southern Observatory (ESO) telescopes are being used to search for the subtle signs of magnetic fields in other stars and even to map out the star spots on their surfaces.

Synopsis: High-resolution observations using the Hinode satellite reveal the existence of small magnetic elements inside solar supergranules. These elements have been proved to feed the magnetic field that covers the entire surface of the Sun.

In this special edition, Nils Olsen from DTU Space joins the show to discuss the latest measurements of Earth's magnetic field and changes observed over the last six months by ESA's Swarm mission.
