Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer. Galaxies this faint have never been seen before. The resulting image, shown above in representative color, shows known galaxies in a new light, and previously unknown galaxies probably farther than anything ever seen before. Galaxies as dim as magnitude 30 are visible. Astronomers are learning from the HDF how different the young universe was from the familiar universe of today.
