WASHINGTON: The Earth’s life-sustaining atmosphere would probably have been severely affected by the Sun’s flares if the Blue Marble did not have magnetosphere, a NASA study has revealed.
Magnetosphere is a natural magnetic bubble which protects a planet’s atmosphere. Without it, a planet’s atmosphere is intensely vulnerable to eruptions from the Sun, the study said.
On the Earth, the magnetosphere deflects some of the impact of the solar eruptions. Without it, the Earth would have become like its neighbour, Venus.
Larger eruptions of solar material called coronal mass ejections (CMEs) occur at times that can disrupt the atmosphere around a planet.
