The Hubble Ultra-Deep Field (HUDF) is a deep-field image of a small region of space in the constellation Fornax, containing an estimated 10,000 galaxies.The original data for the image was collected by the Hubble Space Telescope from September 2003 to January 2004 and the first version of the image was released on March 9, 2004.

The Hubble Deep Field (HDF) is an image of a small region in the constellation Ursa Major, constructed from a series of observations by the Hubble Space Telescope. It covers an area about 2.6 arcminutes on a side, about one 24-millionth of the whole sky, which is equivalent in angular size to a tennis ball at a distance of 100 metres. [ 1 ]
The first deep-field image to receive a great deal of public attention was the Hubble Deep Field, observed in 1995 with the WFPC2 camera on the Hubble Space Telescope. Other space telescopes that have obtained deep-field observations include the Chandra X-ray Observatory , the XMM-Newton Observatory, the Spitzer Space Telescope , and the James ...
UDF 2457 is the Hubble Ultra Deep Field (UDF) identifier for a red dwarf star calculated to be about 59,000 light-years (18 kiloparsecs) from Earth [2] with a very dim apparent magnitude of 25. [1] The Milky Way galaxy is about 100,000 light-years in diameter, [3] and the Sun is about 25,000 light-years from the Galactic Center. [4]
Its first known imaging was in Hubble Space Telescope's Hubble Ultra Deep Field, the most detailed deep space picture at that time. [2] The galaxy was observed in August and September 2009. [ 2 ] [ 8 ] The image data was released to the scientific community, which led to the galaxy's detection by the teams of Bouwens, [ 1 ] Bunker [ 5 ] and ...

UDFj-39546284 is a high-redshift Lyman-break galaxy discovered by the Hubble Space Telescope in infrared Hubble Ultra-Deep Field (HUDF) observations in 2009. The object, located in the Fornax constellation, was identified by G. Illingworth (UC Santa Cruz), R. Bouwens (UC Santa Cruz and Leiden University) and the HUDF09 Team during 2009 and 2010.
A unique window on the Universe enabled by Hubble are the Hubble Deep Field, Hubble Ultra-Deep Field, and Hubble Extreme Deep Field images, which used Hubble's unmatched sensitivity at visible wavelengths to create images of small patches of sky that are the deepest ever obtained at optical wavelengths. The images reveal galaxies billions of ...
