19 face-on spiral galaxies from the James Webb Space Telescope in near- and mid-infrared light. Older stars appear blue here, and are clustered at the galaxies’ cores. Glowing dust, showing where it exists around and between stars – appearing in shades of red and orange.
There are a few exceptions such as the Andromeda Galaxy, the Whirlpool Galaxy, and others, but most simply have a catalog number. In the 19th century, the exact nature of galaxies was not yet understood, and the early catalogs simply grouped together open clusters, globular clusters, nebulas, and galaxies: the Messier catalog has 110
Name based on the brightest galaxy in the group when that name is commonly used for identification (e.g. the M81 Group); this is only applicable to groups of galaxies within approximately 50 Mpc; The most commonly-used catalog number (e.g. Abell 3266) Note that group and cluster names are proper nouns.
CEERS-2112 is the most distant barred spiral galaxy observed as of 2023. [1] The light observed from the galaxy was emitted when the universe was only 2.1 billion years old. It was determined to be similar in mass to the Milky Way .
In astronomy, a blue compact dwarf galaxy (BCD galaxy) is a small galaxy which contains large clusters of young, hot, massive stars. These stars, the brightest of which are blue, cause the galaxy itself to appear blue in colour. [15] Most BCD galaxies are also classified as dwarf irregular galaxies or as dwarf lenticular galaxies. Because they ...
NGC 4670 is a blue compact galaxy in the constellation Coma Berenices.The galaxy lies about 60 million light years away from Earth, which means, given its apparent dimensions, that NGC 4670 is approximately 25,000 light years across. [1]
A galaxy is a system of stars, stellar remnants, interstellar gas, dust, dark matter, bound together by gravity. The word is derived from the Greek galaxias, literally 'milky', a reference to the Milky Way galaxy that contains the Solar System.
Cosmic latte is the average color of the galaxies of the universe as perceived by a typical human observer from the position of the Earth, found by a team of astronomers from Johns Hopkins University (JHU).
