  2. Hubble Ultra-Deep Field - Wikipedia

    en.wikipedia.org/wiki/Hubble_Ultra-Deep_Field

    The Hubble eXtreme Deep Field (HXDF), released on September 25, 2012, is an image of a portion of space in the center of the Hubble Ultra Deep Field image. Representing a total of two million seconds (about 23 days) of exposure time collected over 10 years, the image covers an area of 2.3 arcminutes by 2 arcminutes, [ 18 ] or about 80% of the ...

    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 ]

    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.

  6. 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 ...

  7. 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. In some contexts, it is used to refer to interstellar space.

    A Deep Space Optical Communication demonstration is included with NASA's Psyche mission, launched on October 13, 2023. The Psyche spacecraft will explore the metal asteroid 16 Psyche, reaching the asteroid belt in 2029. [10] [11] [12] DSOC first light was achieved on November 14, 2023. The experiment successfully transmitted a 15-second ultra ...

  9. Cosmic background radiation - Wikipedia

    en.wikipedia.org/wiki/Cosmic_background_radiation

    The discovery (by chance in 1965) of the cosmic background radiation suggests that the early universe was dominated by a radiation field, a field of extremely high temperature and pressure. [ 1 ] The Sunyaev–Zel'dovich effect shows the phenomena of radiant cosmic background radiation interacting with " electron " clouds distorting the ...
