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.
In case you didn’t know, the universe is a terribly hostile place for most lifeforms. At least, it is if you don’t have proper protection. Take our own star, for example. The Sun gives life to everything on Earth, but it is also a violent inferno that shoots off high energy particles that could seriously disrupt Earth’s natural systems. Fortunately, for us, our planet has protection. Ultimately, the Earth is encased in a magnetic field, which is generated by the rotating, liquid iron core at…
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.

Patterns in Earth's Magnetic Field Morph Every 1000 Years --"The Reason is a Mystery" - The Daily Galaxy 7/9/17
Taking a deep dive into our planet’s turbulent core 3000 kilometers below surface level, geophysicists have emerged with high-definition 3D simulations showing the hidden mechanisms that govern the Earth’s magnetic field.
