Importance of Earth's Magnetosphere


 Earth's Magnetosphere

Here's why we're not all on fire right now. Earth's Magnetosphere is big bubble of magnetism that surrounds our planet and protects us from the fiery sun. The magnetosphere deflects most of the charged particles in the sun's solar winds. This preserves the earth's protective layers, like ozone which shields us from ultraviolet radiation.

Earths Mars Magnetosphere

Without the magnetosphere earth would look  a lot like Mars. The red planet lost most of its magnetosphere about 4.2 billion years ago. The solar winds are thought to have stripped away most of its atmosphere making mars the stark, barren planet it is today.

Understanding our magnetosphere may someday help us predict space weather. Extreme space weather can disrupt communication networks, GPS navigation and electrical power grids.
