  2. Deep space exploration - Wikipedia

    en.wikipedia.org/wiki/Deep_space_exploration

    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.

  3. List of deep fields - Wikipedia

    en.wikipedia.org/wiki/List_of_Deep_Fields

    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 ...

  4. Outer space - Wikipedia

    en.wikipedia.org/wiki/Outer_space

    Deep space is defined by the United States government as all of outer space which lies further from Earth than a typical low-Earth-orbit, thus assigning the Moon to deep-space. [118] Other definitions vary the starting point of deep-space from, "That which lies beyond the orbit of the moon," to "That which lies beyond the farthest reaches of ...

  5. List of Solar System probes - Wikipedia

    en.wikipedia.org/wiki/List_of_Solar_System_probes

    This is a list of space probes that have left Earth orbit (or were launched with that intention but failed), organized by their planned destination. It includes planetary probes, solar probes, and probes to asteroids and comets, but excludes lunar missions, which are listed separately at List of lunar probes and List of Apollo missions.

  6. Webb's First Deep Field - Wikipedia

    en.wikipedia.org/wiki/Webb's_First_Deep_Field

    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.

  7. Space exploration - Wikipedia

    en.wikipedia.org/wiki/Space_exploration

    Deep space exploration is the branch of astronomy, astronautics and space technology that is involved with the exploration of distant regions of outer space. [49] Physical exploration of space is conducted both by human spaceflights (deep-space astronautics) and by robotic spacecraft.

  8. Hubble Deep Field - Wikipedia

    en.wikipedia.org/wiki/Hubble_Deep_Field

    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 ]

  9. List of active Solar System probes - Wikipedia

    en.wikipedia.org/wiki/List_of_active_Solar...

    Solar System space probes operational as of November 2024. This is a list of active space probes which have escaped Earth orbit. It includes lunar space probes, but does not include space probes orbiting at the Sun–Earth Lagrangian points (for these, see List of objects at Lagrangian points). A craft is deemed "active" if it is still able to ...
