- HUBBLE'S DEEPEST-EVER VIEW OF THE UNIVERSE
- UNVEILS MYRIAD GALAXIES BACK TO THE BEGINNING
- OF TIME
-
- Several hundred never before seen galaxies are visible in this
- "deepest-ever" view of the universe, called the Hubble Deep Field
- (HDF), made with NASA's Hubble Space Telescope. Besides the classical
- spiral and elliptical shaped galaxies, there is a bewildering variety
- of other galaxy shapes and colors that are important clues to
- understanding the evolution of the universe. Some of the galaxies may
- have formed less that one billion years after the Big Bang.
-
- 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 (about 25% of the entire HDF is shown here).
- 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. (The
- relatively bright object with diffraction spikes just left of center
- may be a 20th magnitude star.) 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 (342 frames total
- were taken, 276 have been fully processed to date and used for this
- picture) with the Wide Field and Planetary Camera 2 (WFPC2), for ten
- consecutive days between December 18 to 28, 1995. This picture is from
- one of three wide-field CCD (Charged Coupled Device) detectors on the
- WFPC2.
-
- This "true-color" view was assembled from separate images were taken in
- blue, red, and infrared light. By combining these separate images into
- a single color picture, astronomers will be able to infer -- at least
- statistically -- the distance, age, and composition of galaxies in the
- field. Bluer objects contain young stars and/or are relatively close,
- while redder objects contain older stellar populations and/or farther
- away.
-
- This material was presented to the 187th meeting of the American
- Astronomical Society in San Antonio, Texas on January 15, 1996.
