JADES-GS-z13-0 is a high-redshift Lyman-break galaxy discovered by the James Webb Space Telescope (JWST) during NIRCam imaging for the JWST Advanced Deep Extragalactic Survey (JADES) on 29 September 2022.
NGC 1052-DF2, an ultra diffuse galaxy. An ultra diffuse galaxy (UDG), or dark galaxy, [1] is an extremely low luminosity galaxy, the first example of which was discovered in the nearby Virgo Cluster by Allan Sandage and Bruno Binggeli in 1984. [a] These galaxies have been studied for many years prior to their renaming in 2015. Their lack of ...
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.

Barnard 68 is a molecular cloud, dark absorption nebula or Bok globule, towards the southern constellation Ophiuchus and well within the Milky Way galaxy at a distance of about 125 parsecs (407 lightyears). [2] It is both close and dense enough that stars behind it cannot be seen from Earth.
As in all real images from our Arm of the galaxy much is obscured by the Great Rift, dark dust clouds that span from Cygnus to Centaurus. In astronomy , the Great Rift (sometimes called the Dark Rift or less commonly the Dark River ) is a dark band caused by interstellar clouds of cosmic dust that significantly obscure ( extinguish ) the center ...

The quasar is near the center of the image; no obvious host galaxy is seen. Near the top of the image is a strongly disturbed and star-forming galaxy. Near the quasar is a blob of gas that is apparently being ionized by the quasar radiation. The pointlike object on the lower right is a foreground star seen by chance in the field of view.
