astronomiset

Astronomiset is the plural form of the Finnish adjective astronominen, meaning related to astronomy or the science of celestial objects. It is used in neutral, scientific contexts to describe phenomena, measurements, data, or objects connected to astronomy. The term appears in research articles, textbooks, and general overviews to indicate that a subject belongs to or concerns the field of astronomy rather than other disciplines.

Common uses include describing observations, measurements, or quantities: esimerkiksi astronomiset havainnot (astronomical observations), astronomiset mittaukset (astronomical measurements), astronomiset suureet (astronomical quantities such as distances, luminosities, or redshifts). It also modifies objects or events, such as astronomiset objektit (celestial objects) and astronomiset tapahtumat (astronomical events) like eclipses or supernovae. The phrase can cover data sets, models, instruments, or simulations used in astronomical research, for example astronomiset kartat or astronomiset simuloinnit.

The term is distinct from astrologinen, which relates to astrology and is not used in a strictly scientific sense. Astronomiset describe scientifically observable aspects of the cosmos, whereas astrologinen refers to beliefs about natal charts and horoscopes. In Finnish, the adjective forms adapt to number and case, so plural nouns are paired with astronomiset, while singular forms use astronominen.

Etymology traces astronominen to the root relating to astronomy, with the -nen suffix forming a Finnish adjective. The plural -iset ending marks the grammatical number in phrases like astronomiset havainnot. The term is common in Finnish-language astronomy literature and educational material.
