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 ...
The Hubble Deep Field South is a composite of several hundred individual images taken using the Hubble Space Telescope's Wide Field and Planetary Camera 2 over 10 days in September and October 1998. It followed the great success of the original Hubble Deep Field in facilitating the study of extremely distant galaxies in early stages of their ...
GOODs used the Hubble Space Telescope's Advanced Camera for Surveys with four filters, centered at 435, 606, 775 and 850 nm. The resulting map covers 30 times the area of the Hubble Deep Field to a photometric magnitude less sensitivity, and has enough resolution to allow the study of 1 kpc-scale objects at redshifts up to 6. It also provides ...
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.

Webb's First Deep Field was taken by the telescope's Near-Infrared Camera (NIRCam) and is a composite produced from images at different wavelengths, totalling 12.5 hours of exposure time. [3] [4] SMACS 0723 is a galaxy cluster visible from Earth's Southern Hemisphere, [5] and has often been examined by Hubble and other telescopes in search of ...
UDFy-38135539 is within the annotated red circle Location of UDFy-38135539 (HUDF.YD3) UDFy-38135539 (also known as "HUDF.YD3") is the Hubble Ultra Deep Field (UDF) identifier for a galaxy which was calculated as of October 2010 to have a light travel time of 13.1 billion years [2] with a present proper distance of around 30 billion light-years.
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]
