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 ...
Cosmos Redshift 7 (also known as COSMOS Redshift 7, Galaxy Cosmos Redshift 7, Galaxy CR7 or CR7) is a high-redshift Lyman-alpha emitter galaxy. At a redshift z = 6.6, [ 1 ] the galaxy is observed as it was about 800 million years after the Big Bang , during the epoch of reionisation . [ 1 ]
Stephenson 2, also known as RSGC2 (Red Supergiant Cluster 2), is a young massive open cluster belonging to the Milky Way galaxy. It was discovered in 1990 as a cluster of red supergiants in a photographic, deep infrared survey by the astronomer Charles Bruce Stephenson, after whom the cluster is named.
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]
A Hubble Space Telescope image of the supergiant elliptical galaxy ESO 306-17. Supergiant elliptical galaxies are some of the largest galaxies known. The Condor Galaxy is a colossal spiral galaxy disturbed by the smaller IC 4970 .
It lies along the line between the stars Epsilon Virginis and Denebola (Beta Leonis). [c] The galaxy can be observed using a small telescope with a 6 cm (2.4 in) aperture, extending across an angular area of 7.2 × 6.8 arcminutes at a surface brightness of 12.9, with a very bright, 45 arcsecond core.

The galaxy is filled with bright blue star clusters triggered by the merger, some containing as many as one million stars. [2] It is the largest disrupted spiral galaxy of its sort. It is hypothesized that a more compact intruder galaxy crossed in front of the Tadpole Galaxy—from left to right from the perspective of Earth—and was slung ...
The Sombrero Galaxy (also known as Messier Object 104, M104 [4] or NGC 4594) is a peculiar galaxy of unclear classification [5] in the constellation borders of Virgo and Corvus, being about 9.55 megaparsecs (31.1 million light-years) [2] from the Milky Way galaxy.
