Hubble Deep Field
(HDF, HDF-N, Hubble Deep Field North)
(highly-detailed image of a small region of the sky taken with HST)
The Hubble Deep Field (HDF) is an image of a small region of
the sky (a survey field, within constellation Ursa Major)
taken over a very long exposure with the Hubble Space Telescope aiming to image as
distant galaxies as possible.
- right ascension: 12h36m49.4000s
- declination: +62deg12m58.000s
- Size: 3' x 3' (11.5 square arcminutes)
- Exposure: on the order of 4 days
- Date: December 1995
The HDF region of the sky has been studied at other wavelengths
in order to associate other signal with the HDF visual images.
Since the HDF, the Hubble Deep Field South was made in 1998,
the Hubble Ultra-Deep Field was made in 2003/2004
and the Hubble Extreme Deep Field in 2012.
