The Hubble Extreme Deep Field

The Hubble Extreme Deep Field is most distant image of the Universe ever created.  Its diameter is one tenth the width of the full moon, its area is one 30 millionth of the entire sky.  Within this field of view there are more than 5000 galaxies, 600 trillion stars and 50 quadrillion planets and moons. The light from the most distant visible objects was created more than 13 billion years ago, when the Universe was only 5% of it’s current age.  This photograph is a slice of infinity, proof of the immense scale of reality.
