The Earth's Magnetosphere

The Earth's magnetosphere is a protective magnetic shield created by the planet's liquid iron core. It extends thousands of kilometers into space, deflecting most of the Sun's charged particles—solar wind—that would otherwise strip away the atmosphere and harm living organisms. When solar particles interact with the magnetosphere, they can cause phenomena like the auroras (Northern and Southern Lights). This magnetic shield is vital for maintaining Earth's environment and habitability, acting as a barrier that safeguards the planet from space weather and cosmic radiation.
