Watch | NASA zooms into the most distant galaxy it has ever seen

When the Hubble Space Telescope looks into the deepest reaches of space, it is also looking backward in time. The further away the light source, the older it is.NASA uses the Hubble to zoom into the oldest and farthest galaxy Hubble has ever seen. The light from the galaxy, called GN-z11, is 13.4 billion years old, or just 400 million years after the big bang- the beginning of time.The light is so old, it was created before the Earth formed.
