What Are Constellations and Asterisms?

The spoken lesson

"Modern astronomers divide the entire sky into eighty-eight regions called constellations. These regions help locate stars, galaxies, nebulae, and other objects. An asterism is a noticeable star pattern that may lie inside one constellation or cross several. The Big Dipper, Southern Cross, Summer Triangle, and Orion's Belt are familiar examples in some traditions. Cultures around the world have created different sky patterns, stories, calendars, and navigation systems. Stars that appear close together may actually be separated by enormous distances. Earth's rotation and orbit change where and when patterns appear, and latitude changes what an observer can see. Constellations organise sky regions; asterisms and cultural patterns help people recognise and interpret the sky." DESIGN REQUIREMENTS: Show several cultural interpretations without appropriating sacred knowledge. Use accurate modern boundaries separately from story patterns. Avoid laser imagery, one-culture dominance, physically connected stars, or universal seasonal claims.
