$Hubble Goes to the eXtreme to Assemble Farthest Ever View of the Universe Date- 25th Sept 12 Source- http://hubblesite.org/newscenter/archive/releases/2012/37/ Like photographers assembling a portfolio of best shots, astronomers have assembled a new, improved portrait of mankinds 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 Hubbles 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. The public is invited to participate in a Meet the Hubble eXtreme Deep Field Observing Team webinar, where three key astronomers of the XDF observing team will describe how they assembled the landmark image and explain what it tells us about the evolving universe. Participants will be able to send in questions for the panel of experts to discuss. The webinar will be broadcast at 1:00 p.m. EDT on Thursday, September 27, 2012.
