Earth's invisible bodyguard, deflecting solar punches so your DNA stays unscrambled.
means The region of space around a planet where its magnetic field dominates over the solar wind, shaping a protective magnetic bubble.
from Built from 'magnet' — tracing back to Magnesia, a region of ancient Greece famed for lodestone, the naturally magnetic rock the Greeks puzzled over — plus 'sphere,' from Greek 'sphaira' meaning ball or globe. The compound word itself is a 20th-century scientific coinage, assembled once satellites and space probes confirmed Earth really does wear a magnetic shell, giving old Greek rock-wonder a new cosmic address.
