New Hubble peers deep in cosmic past and future (2002)
WASHINGTON (Reuters) -- A new wide-angle view of the universe looks back to a mere billion years after the Big Bang, revealing secrets about the lives of galaxies and the black holes at their hearts, scientists reported on Thursday.

Assuming that galaxy traveled away from us and we both left the big bang at the same time. Then if that light left that galaxy when that galaxy was just 1 billion years old and traveled for 12 billion years to reach us, then we must be at l2 billion light years from where that galaxy was when the light was produced. If the galaxys are going in opposite directions, then seems like our galaxy would have had to travel at almost 11/13 times the speed of light to be 12 billion light years away from where that galaxy was after it had traveled 1 billion years.
If the galaxies are going in the same direction. Then our galaxy has to be going even faster to receive the light 12 billion years later.
If the galaxies are going slow like on the order of 1/4 the speed of light, then it seems like the earliest we should be able to see is 3/4ths the age of the universe.
What am I missing?
Here's a blurb from the Hubble Site as well, with links to images. Thanks for the post.
Hubble Goes 'Deep' to Sample Young Galaxies
NASA's Hubble Space Telescope reached back to nearly the beginning of time to sample thousands of infant galaxies. This image, taken with Hubble's Advanced Camera for Surveys, shows several thousand galaxies, many of which appear to be interacting or in the process of forming. Some of these galaxies existed when the cosmos was less than about 2 billion years old. The foreground galaxies, however, are much closer to Earth. Two of them [the white, elongated galaxies, left of center] appear to be colliding.
This image represents less than one-tenth of the entire field surveyed by Hubble. The full field, consisting of about 25,000 galaxies, is part of a larger survey called the Great Observatories Origins Deep Survey (GOODS), the most ambitious study of the early universe yet undertaken with the Hubble telescope. This survey targeted two representative spots in the sky - one in the Northern Hemisphere and the other in the Southern Hemisphere. This image represents the southern field, located in the constellation Fornax. The entire GOODS survey reveals roughly 50,000 galaxies. Astronomers have identified more than 2,000 of them as infant galaxies, observed when the universe was less than about 2 billion years old.
Because infant galaxies are very faint and very rare, astronomers are using Hubble to search for them over a relatively wide swath of sky. In fact, the new observations cover about 60 times the area of the original Hubble Deep Field Observations, obtained in 1995. Astronomers also are using the Chandra X-ray Observatory to search the GOODS fields for the earliest black holes in the universe. The Space Infrared Telescope Facility (SIRTF) will sample these same fields soon after it is launched in August 2003.
By combining light from all three of NASA's great observatories with data from ground-based telescopes, astronomers hope to build a coherent picture of galaxy evolution.
This image of the southern field was assembled from observations taken between July 2002 and February 2003.

Larger version LINK Absolutely remarkable!
I have a relationship with the Creator. And I don't believe the universe is 13 billion years old. Although I'm not absolutely positive that it's not.
So maybe I'm missing theory of relativity.
I don't know, the fastest I've been is 150mph. Light didn't seem much different. But the dotted lines on the road did blurr together.

If you are on a plane travelling at 300 miles per hour and you look over and see a fly going by in the cabin. how fast is the fly going?????
GOODS aims to unite extremely deep observations from NASA's Great Observatories, SIRTF, Hubble, and Chandra, ESA's XMM-Newton, and from the most powerful ground-based facilities, to survey the distant universe to the faintest flux limits across the broadest range of wavelengths.
GOODS incorporates a SIRTF Legacy Program to carry out the deepest observations with that facility at 3.6 to 24 microns, an HST Treasury Program using the new Advanced Camera for Surveys to obtain deep, high angular resolution imaging at optical wavelengths, and the deepest X-ray observations with Chandra and XMM-Newton.
GOODS will survey a total of roughly 320 square arcminutes in two fields centered on the Hubble Deep Field North and the Chandra Deep Field South.
The space-based observations will be complemented by ground-based imaging and spectroscopy, including an extensive commitment of ESO and NOAO observing time.
