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 (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 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.

Being essentially empty, outer space allows the earliest (redder) galaxies to be viewed without obstruction, as in the Webb's First Deep Field image. Outer space (or simply space) is the expanse that exists beyond Earth's atmosphere and between celestial bodies. [1]
Webb's First Deep Field. Webb's First Deep Field is the first operational image taken by the James Webb Space Telescope (JWST). The deep-field photograph, which covers a tiny area of sky visible from the Southern Hemisphere, is centered on SMACS 0723, a galaxy cluster in the constellation of Volans.
Deep-space exploration is the branch of astronomy, astronautics, and space technology that is involved with exploring the distant regions of outer space. [1] However, little consensus has been reached on the meaning of "distant" regions. In some contexts, it is used to refer to interstellar space.
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 ...
HDF – (data/celestial object) Hubble Deep Field, an area of the sky with little foreground obscuration that was observed deeply with the Hubble Space Telescope; also the name for the data product itself. HDFS – Hubble Deep Field South
