Hubble eXtreme Deep Field!

I finally changed out my desktop background. You'll see why. Amazing!
Numerous image sizes available to view. Mini version below.

September 25, 2012: Like photographers assembling a portfolio of best shots, astronomers have assembled a new, improved portrait of mankind's deepest-ever view of the universe. Called the eXtreme Deep Field, or XDF, the photo was assembled by combining 10 years of NASA Hubble Space Telescope photographs taken of a patch of sky at the center of the original Hubble Ultra Deep Field. The XDF is a small fraction of the angular diameter of the full Moon. 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 2003 and 2004. 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 new full-color XDF image reaches much fainter galaxies and includes very deep exposures in red light from Hubble's new infrared camera, enabling new studies of the earliest galaxies in the universe. The XDF contains about 5,500 galaxies even within its smaller field of view. The faintest galaxies are one ten-billionth the brightness of what the human eye can see.

Does this show all the galaxies that we will EVER see in that area of the sky? Are any additional galaxies so far away that their light has not reached us (and never will, if the accelerating expansion of the universe is correct?) Have telescopes reached their ultimate limit? The James Webb Space Telescope will show these galaxies in more detail, but will it show any more?

Thanks Linton. Sometimes when I'm inclined to get all "wrapped up" in events going on in the world around me, it's nice to see something like this to help put everything in it's proper perspective. smile

Thanks much for passing this on!
