The Hubble Deep Field North is one of the deepest, sharpest, multi-color images of the faintest universe in visible light. The Hubble Space Telescope was pointed into an empty point in the Northern sky to observe about a thousand never-before-seen galaxies in the universe. The Hubble Deep Field South complements the original Hubble Deep Field.
The objects in the sky are about 2 to 10 billion light years away so when we view the galaxies they appeared 2 to 10 billion years ago in the early universe. The depth of the Hubble Deep Fields are equal to billions of light years.
By looking in the sky, you can tell there are many different galaxies amongst the universe. Some known as elliptical, spiral, and irregular. They also have different frequencies, which make them their own galaxy. Sometimes you may come across very faint and dull galaxies or you may come across very bright and distinguished galaxies. The size difference of galaxies can vary also.
