It was discovered by the French expedition, 1837-40, under Captain Jules Dumont d'Urville, and named by him for his chief expedition ship, the Astrolabe.

Geology

Astrolabe Island is predominantly volcanic rocks, with coarse grained mafic dolerite making up most of the landing site on the east end. The steep pyramid peaks, called the Devils Teeth, may be the vents of an old volcanic complex, probably related to the Shetland subduction zone to the north.
