- An archipelagic state is an island country that consists of one or more archipelago. The designation is legally defined by the United Nations Convention on the Law of the Sea of 1982 (UNCLOS III). The Bahamas, Fiji, Indonesia, Papua New Guinea, and the Philippines are the five original sovereign states that obtained approval in the UNCLOS signed in Montego Bay, Jamaica on 10 December 1982 and qualified as the archipelagic states.

Astronomy is a natural science that studies celestial objects and phenomena. It uses mathematics, physics, and chemistry in order to explain their origin and evolution. Objects of interest include planets, moons, stars, nebulae, galaxies, meteoroids, asteroids, and comets. Relevant phenomena include supernova explosions, gamma ray bursts, quasars, blazars, pulsars, and cosmic microwave background radiation. More generally, astronomy studies everything that originates beyond Earth’s atmosphere. Cosmology is a branch of astronomy that studies the universe as a whole.
