Morphology
Each constituent contributes directly to the overall meaning: 'north' specifies the direction/hemisphere, 'celestial' indicates the sky/stars, and 'pole' denotes a fixed axis point. This straightforward compositional structure (direction + domain + point) is cross-linguistically common, so a B1 learner who knows the three words can reliably infer the MWE's meaning.
Etymology
North Celestial Pole is the point in the sky straight above Earth's North; like a pole in the sky, the stars seem to turn around it and the bright star Polaris sits very close, so astronomers use it as a 'reference point' for finding direction and mapping the night sky.
