The '''Hubble Ultra-Deep Field''' is an image taken by the [[Hubble Space Telescope]] of a small patch of sky containing nearly 10,000 [[galaxies]].<ref name=spacetelescope>[https://www.spacetelescope.org/images/heic0611b/ Hubble Ultra Deep Field] from spacetelescope.com</ref> Taken in 2004, it is furthest image ever made in [[visible light]], in fact [[infrared]] light must be used to see further. Similar images were also made in the [[ultraviolet]] and [[infrared]] bands. The image was created using 800 different exposures producing a combined exposure time of 11.3 days.<ref name=spacetelescope/>
The photograph is of a small area of sky in the Fornax [[constellation]], below the constellation of [[Orion]].<ref>[http://hubblesite.org/news_release/news/2004-07/58-hubble-ultra-deep-field Hubble Ultra Deep Field] from hubblesite.org</ref> This area was choosen as it does not lie in the plane of the [[Milky Way]], reducing the number of Milky Way's own [[star]]s in the image. The image is 2.3 arcminutes across, about a tenth the width of a full [[moon]].
