Hubble Deep Field North

Image Size 300 DPI: 25 * 25 cm
Representing a narrow "keyhole" view all the way to the visible horizon of the universe, the HDF image covers a speck of sky 1/30th the diameter of the full Moon . This is so narrow, just a few foreground stars in our Milky Way galaxy are visible and are vastly outnumbered by the menagerie of far more distant galaxies, some nearly as faint as 30th magnitude, or nearly four billion times fainter than the limits of human vision. Though the field is a very small sample of sky area it is considered representative of the typical distribution of galaxies in space because the universe, statistically, looks the same in all directions. The image was assembled from many separate exposures with the Wide Field and Planetary Camera 2 for ten consecutive days between December 18 to 28, 1995.
