Astrophotography, also known as astronomical imaging, is the photography or imaging of astronomical objects, celestial events, or areas of the night sky. The first photograph of an astronomical object (the Moon ) was taken in 1840, but it was not until the late 19th century that advances in technology allowed for detailed stellar photography.
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 (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 James Webb Space Telescope is a space telescope operated by NASA and designed primarily to conduct infrared astronomy.Launched in December 2021, the spacecraft has been in a halo orbit around the second Sun–Earth Lagrange point (L 2), about 1.5 million kilometers (900,000 mi) from Earth, since January 2022.
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.

A deep-sky object (DSO) is any astronomical object that is not an individual star or Solar System object (such as Sun, Moon, planet, comet, etc.). [ 1 ] [ 2 ] The classification is used for the most part by amateur astronomers to denote visually observed faint naked eye and telescopic objects such as star clusters , nebulae and galaxies .
The oldest form of astronomy, optical or visible-light astronomy, observes wavelengths of light from approximately 400 to 700 nm. [149] Positioning an optical telescope in space eliminates the distortions and limitations that hamper that ground-based optical telescopes (see Astronomical seeing ), providing higher resolution images.
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 ...
