NASA’s new study has revealed that the Earth’s life-sustaining atmosphere would have been severely affected by the Sun’s flares if it did not have magnetosphere.
Magnetosphere acts like a natural magnetic bubble which helps protect a planet’s atmosphere. In its absence, a planet’s atmosphere is intensely vulnerable to eruptions from the Sun.
The magnetosphere on Earth has prevented it from becoming like Venus by deflecting some of the impact of the solar eruptions.
Venus is an inhospitable planet, which is 10 times hotter than the Earth. It possesses such a thick atmosphere that the longest any spacecraft had survived on its surface was for only two hours.
