Universe Poster by National Geographic
If you really want to feel small, take a close look at the National Geographic Universe poster. Measured in light years, this poster shows the relative positions of galaxies. The level of enormity is incomprehensible and amazing! This chart is like having 6 charts in one by illustrating the Milky Way, our galaxy, nearby superclusteras as well as nearby galaxies and then the cylindrical diagram of our solar system.
