This is is a color composite image in the green, red and infrared bands of a patch of the sky known as the COSMOS field, as imaged by the Subaru Telescope in Hawaii.
The galaxies are seen at such large distances that the light from them has taken billions of years to reach Earth.
The light from the faintest galaxies in this image was emitted when the universe was less than 10 percent of its present age.
