Supercomputer model of Earth's magnetic field. Scientists believe that gyrating iron fluid generates Earth's magnetic field, like a giant dynamo. Both yearly and millennial-scale changes in the field have been attributed to the swirling, spinning outer core. Tracking changes in the magnetic field helps researchers create models of how the dynamo may work.

'Magnetic' Discovery May Reveal Why Earth Supports Life and Mars Doesn't

Earth's magnetic field, which protects the planet from harmful blasts of solar radiation, is much older than scientists had previously thought. This invisible, protective shield likely existed shortly after the planet formed; a finding that could shed light on why Earth is habitable and Mars is not. Earth's magnetic field helped make life on the planet possible. Without our magnetic field, solar winds would strip away the planet's atmosphere and oceans.

Magnetic Fields of Venus, Earth and Mars. I love this piece because it reminds me of just how special,fragile and protected Mother Earth is when it comes to having and feeling the full on powerful force of the SUN.

A Timelapse Of Our Planet's Surprisingly Turbulent Magnetic Field

mn: Using my METHOD, it took me one day to FIND this model, I did NOT MAKE it: Use the Magnetic Field of Earth to charge an array of Super Powerful UV Lasers shot at a Dish that aims it at the Sun (at least most of it) and ATTENUATES the UV that REACHES the Atmosphere. THIS is where I want to focus my work now, NOT under a tree in this case...
