astronomiche

Astronomiche is the feminine plural form of the Italian adjective astronomico (masculine singular) or astronomica (feminine singular). It denotes a relation to astronomy, the science that studies celestial bodies and phenomena. In use, the adjective agrees with the noun it modifies, as in osservazioni astronomiche, strumenti astronomici, o fenomeni astronomici.

The term derives from the noun astronomia, which in turn comes from the Greek words astron, meaning star, and nomos, meaning law or arrangement. In Italian, related forms such as astronomico, astronomica, and astronomiche share the same semantic field and follow standard gender and number agreement.

In practice, astronomiche appears in scientific, educational, and journalistic contexts to describe objects, methods, or results connected with astronomy. Common collocations include osservazioni astronomiche (astronomical observations), dati astronomici (astronomical data), immagini astronomiche (astronomical images), and modelli astronomici (astronomical models). While primarily used in formal or technical language, the term also appears in general writing when a precise reference to astronomy is required.
