Earth's magnetic field may be more powerful than we thought

"New data collected by China's Chang'e 4 lunar lander shows that our magnetosphere's influence is so powerful that it extends farther into space than previously believed, stretching even beyond the moon."

"Scientists had long assumed most of the moon lay beyond the protection of Earth's magnetic field, but in 2019, scientists began noticing something odd about the experiment's data that suggested the moon was somewhat protected from galactic cosmic rays."

Galactic cosmic rays are a significant source of radiation in space, but Earth's magnetic field protects the planet from their harmful effects. New data from China's Chang'e 4 lunar lander reveals that this magnetic influence extends beyond the moon, creating a cavity in space where cosmic rays are deflected. This discovery challenges previous assumptions about the moon's exposure to cosmic radiation and indicates that Earth's magnetism shields a larger area in space than expected, impacting future astronaut missions to the lunar surface.
