Swarm and Titan

23 June 2014

The European Space Agency (ESA) is studying Earth's magnetic field – from space (see http://phys.org/print322463763.html). Meanwhile, NASA is organising a mission to Titan, the largest moon of Saturn – see http://phys.org/print322421695.html. It is described as an almost Earth like world, a frozen version of the Earth as it was several billion years ago. Titan is visualised as a carbon copy of the Earth prior to the oxygen dominated atmosphere.

Over at http://phys.org/print322466906.html … there is a video which shows changes in Earth's magnetic field between January and June this year. It is the magnetic field that protects us from cosmic radiation, we are informed, or charged particles emitted by the Sun. The magnetic field is in a permanent state of flux. Worth having a peak.
