Journey to the edge of the known universe and come back to Earth in this exploration of the vastness of space. This video shows the world’s most complete four-dimensional map of the universe, which is maintained by the American Museum of Natural History.

Video Summary

Beginning over the Himalayan mountains of Tibet, we move outward, exploring the size of our solar system, galaxy, and universe. Around the Earth we see hundreds of satellites, and further away, about one light second from earth, the orbit of the Moon. Saturn is the next landmark, at about a light hour out, followed by the boundaries of our solar system in about a “light day.” Continuing outward we eventually run into the furthest galaxies, which are over 100 million light years away. Finally we see quasars, the furthest objects we can see (over thirteen billion light years away).
