Tähtikuvioiden

Tähtikuvioiden, meaning "constellations" in Finnish, refers to the patterns formed by stars in the night sky as seen from Earth. These patterns have been recognized and named by various cultures throughout history, often drawing inspiration from mythology, animals, or everyday objects. While the stars themselves are not physically close to each other, their apparent proximity from our perspective creates these recognizable shapes.

Historically, constellations served practical purposes. Sailors used them for navigation, and ancient cultures often integrated them into their calendars and religious practices. The International Astronomical Union (IAU) officially recognizes 88 constellations, which divide the entire celestial sphere. These official constellations are not just the patterns but also the specific regions of the sky associated with them.

Some of the most well-known constellations include Ursa Major (Suuri Karhu), Orion (Orion), and Cassiopeia (Kassiopeia). Each constellation has a rich history and associated lore, often passed down through oral traditions and written records. Observing constellations can be a rewarding way to connect with the night sky and understand humanity's long-standing fascination with the cosmos. Modern astronomy uses constellations as a framework for locating celestial objects and understanding the structure of the universe.
