In the winter of 1995, a series of commands are sent to Hubble's on-board computer that turn the orbiting telescope toward what is apparently an "empty" part of the sky.Hubble's powerful gaze locks onto this single region of space for ten consecutive days, creating a series of exposures that would be known as "The Hubble Deep Field".The Hubble Deep Field was a pretty astonishing idea.Take a telescope out in space and point it at one part of the sky and let it sit.Just take an exposure and then take another one, and then another one, and another one.And then add them all up and what do you see when you do this?That's what Hubble Deep Field is.It is deep and we would see very deep into the universe.And you see galaxies, thousands and thousands of galaxies.A crowded dense field that looks like you're taking a picture of fireflies out in a field at night.And yet, this is a, you know, an "empty" patch of sky.Every smudge of light in this Hubble picture is a galaxy containing billions of stars.These galaxies are captured at various stages of evolution.
