Hubble Extreme Deep Field Pushes Back Frontiers of Time and Space.The Hubble Space Telescope (HST) has
produced one of its most extraordinary views of the Universe to date.
Called the eXtreme Deep Field, the picture captures a mass of galaxies
stretching back almost to the time when the first stars began to shine.
But this was no simple point and snap - some of the objects in this image are
too distant and too faint for that.
Rather, this view required Hubble to stare at a tiny patch of sky for more
than 500 hours to detect all the light.
"It's a really spectacular image," said Dr Michele Trenti, a science team
member from the University of Cambridge, UK.
"We stared at this patch of sky for about 22 days, and have obtained a very
deep view of the distant Universe, and therefore we see how galaxies were
looking in its infancy."
The XDF will become a tool for astronomy. The objects
