Planetary shield
From Halopedia, the Halo wiki
Planetary shields were a variant of Forerunner energy shielding technology that could be extended to cover entire planets to protect from stellar radiation. Sections of a planetary shield could be temporarily lowered to allow starships to pass through.[1] Normally, a planetary shield was barely visible, but caused noticeable refraction when opening or during sunset.
Molaetra was protected by a planetary shield.[2]
