It’s like having five posters in one. This
unusual poster illustrates our galaxy,
the Milky Way, nearby galaxies, nearby
superclusters, and the entire known
universe in five cylindrical diagrams. The
cylinders, with grids measuring space
in light years, provide students with a
perspective of distance between celestial
objects both horizontally and vertically,
giving a better idea of the volume of
space. Size: 24 1/4” x 18 1/4”.
