Observations with telescopes on the ground were not able to establish how galaxies formed and evolved in the early universe. The light from those past events is just arriving at Earth now, and so the XDF is a 'time tunnel into the distant past.' The youngest galaxy found in the XDF existed just 450 million years after the universe's birth in the big bang.Д«efore Hubble was launched in 1990, astronomers could barely see normal galaxies to 7 billion light-years away, about halfway across the universe. The early universe was a time of dramatic birth for galaxies containing brilliant blue stars extraordinarily brighter than our sun. Most of the galaxies in the XDF are seen when they were young, small, and growing, often violently as they collided and merged together.

The universe is 13.7 billion years old, and the XDF reveals galaxies that span back 13.2 billion years in time. Bouwens, UCO/Lick Observatory and Leiden University and the HUDF09 Team) Illingworth, UCO/Lick Observatory and the University of California, Santa Cruz R. The new eXtreme Deep Field could be considered a more detailed view of a portion of this image. This image from 2009 shows an updated version of the Hubble Ultra Deep Field. XDF allows us to explore further back in time than ever before', said Garth Illingworth of the University of California at Santa Cruz, principal investigator of the Hubble Ultra Deep Field 2009 (HUDF09) program. 'The XDF is the deepest image of the sky ever obtained and reveals the faintest and most distant galaxies ever seen. Note that this illustration does not show the actual observation of the XDF relative to the location of the moon. A finger held at arm's length would appear to be about twice the width of the moon in this image.

This illustration compares the angular size of the XDF field to the angular size of the full moon. More than 2,000 images of the same field were taken with Hubble's two premier cameras: the Advanced Camera for Surveys and the Wide Field Camera 3, which extends Hubble's vision into near-infrared light.

Hubble pointed at a tiny patch of southern sky in repeat visits (made over the past decade) for a total of 50 days, with a total exposure time of 2 million seconds. The history of galaxies - from soon after the first galaxies were born to the great galaxies of today, like our Milky Way - is laid out in this one remarkable image. Peppered across the field are tiny, faint, more distant galaxies that were like the seedlings from which today's magnificent galaxies grew. These red galaxies are the remnants of dramatic collisions between galaxies and are in their declining years. Magnificent spiral galaxies similar in shape to our Milky Way and the neighboring Andromeda galaxy appear in this image, as do the large, fuzzy red galaxies where the formation of new stars has ceased. In terms of angular size, the field is a fraction the angularДiameter of the full moon, yet it contains thousands of galaxies stretching backДЄcross time. The southern sky, far away from the glare of the Milky Way, the bright plane of This video zooms into the small areas of sky that the Hubble Space Telescope wasДЄimed at to construct the eXtreme Deep Field, or XDF. The faintest galaxies are one ten-billionth the brightness of what the human eye can see. The new full-color XDF image is even more sensitive, and contains about 5,500 galaxies even within its smaller field of view. By collecting faint light over many hours of observation, it revealed thousands of galaxies, both nearby and very distant, making it the deepest image of the universe ever taken at that time.

The Hubble Ultra Deep Field is an image of a small area of space in the constellation Fornax, created using Hubble Space Telescope data from 20. The XDF is a small fraction of the angular diameter of the full moon.
