This piece depicts the northern pole of the celestial sphere. The most prominent stars of our beloved Little and Big Dippers, Cassiopeia, a part of Cephus and the tail of Draco are seen here in relative relationship to the enormity of the Milky Way. We refer to these constellations as circumpolar because they are always visible to us through the year due to our latitude.
What are those other spheres? Other universes?
