[7] [8] The image shows the galaxy's 100 million stars of varying types and thousands of star clusters. [7] [9] [10] In the bottom-left of the image is the galaxy's nucleus, and dust lanes are also visible. [11] Several other deep-space objects are visible in the image, including background galaxies.
HD1 is one of the earliest and most distant known galaxies yet identified in the observable universe, having a spectroscopic redshift of z = 13.27, meaning that the light from the galaxy travelled for 13.5 billion years on its way to Earth, which due to the expansion of the universe, corresponds to a proper distance of approximately 33.4 billion light-years (10.2 billion parsecs).

Insider went through the archives of three NASA observatories — JWST, Hubble, and Chandra X-ray — to find the most iconic pictures of space.
According to recent studies, the Milky Way as well as the Andromeda Galaxy lie in what in the galaxy color–magnitude diagram is known as the "green valley", a region populated by galaxies in transition from the "blue cloud" (galaxies actively forming new stars) to the "red sequence" (galaxies that lack star formation). Star-formation activity ...
IC 1101 is considered a large galaxy characterized by an extensive, diffuse halo. This is the intracluster light, or ICL, free-flying stars that are not bound to any galaxy. This ubiquitous mass of stars within galaxy clusters are usually more concentrated around the brightest cluster galaxies, such as IC 1101, however. [31]
The most powerful telescope to be launched into space has made history by detecting a record number of new stars in a distant galaxy. NASA's James Webb Space Telescope, history's largest and most ...
M82, a starburst galaxy that has ten times the star formation of a "normal" galaxy [111] Stars are created within galaxies from a reserve of cold gas that forms giant molecular clouds. Some galaxies have been observed to form stars at an exceptional rate, which is known as a starburst. If they continue to do so, they would consume their reserve ...
