Sky Cultures and Constellations

Humans naturally look up and see patterns in the night sky. Different cultures have developed shared characters and stories around these patterns, known as constellations. Constellations can include line drawings and representative artwork.

Tukano Constellations Tukano constellations were part of a research survey conducted between 2005 and 2007 that resulted in a doctoral/PhD thesis (Cardoso, 2007).
