Hello, another great classic that we present to you in SHORGB and LRGB and in normal or starless version.Around the keyhole of the Carène NGC 3372. The Carina Nebula (or Great Carina Nebula, NGC 3372) is an emission nebula and a reflection nebula located in the constellation Carina. It was discovered by the French astronomer Nicolas-Louis de Lacaille in 1752 from the Cape of Good Hope in South Africa.[2]At a distance of about 8,500 light-years estimated using recent data from the Gaia satellite[4] and an apparent dimension of 120 arc-minutes, this nebula is one of the largest known HII regions of our galaxy with a wingspan approaching 300 light-years. Although four times larger and brighter than the Orion Nebula, the Carina Nebula is less famous because of its distant position in the southern hemisphere sky. Like the Orion Nebula, NGC 3372 is visible to the naked eye, but we do not distinguish the colors that we see in the telescopic photos, only a whitish spot[8].The Carina Nebula contains the large stellar association OB Carina OB1 and several open clusters containing many O-type stars as well as several Wolf-Rayet stars. The Carina OB1 association encompasses the Trumpler 14 and Trumpler 16 clusters. Trumpler 14 is one of the youngest known clusters, only 6.8 million years old.[9] The star WR 25 is the brightest known in the Milky Way and it is found in Trumpler 16. The famous Eta Carinae star system and the blue supergiant class O HD 93129 A are also found in Trumpler 16. Trumpler 15, Collinder 228, Collinder 232, NGC 3293 and the nebula cluster NGC 3324 are also considered members of the Carina OB1 association. NGC 3293 is the oldest and furthest cluster from Trumpler 14, indicating an always-on star-forming sequence.·         Eta de la Carène (η Car, Eta Carinae) Eta de la Carina (η Car) is an extremely luminous hypergiant star. Estimates of its mass range from 100 to 150 times that of the Sun and its luminosity is about four million times greater than that of the Sun. It is the most massive star that can be studied in great detail because of its location and size. Several other known stars may be brighter and more massive, but the data about them is much less reliable. Stars with a mass greater than 80 times that of the Sun are millions of times brighter. They are rare, barely a few dozen in our galaxy and they are approaching an out-of-control situation known as the Eddington limit, that is, a situation where their radiation pressure takes over gravity. Constituents of the star are then ejected. Stars with more than 120 solar masses exceed the theoretical limit ... Stars with more than 120 solar masses exceed Eddington's theoretical limit and their gravity is barely enough to retain their radiation and gases, which could lead to a supernova or hypernova in the near future. The effects of η Car on the nebula can be observed directly. Dark blood cells and some other less visible objects have tails pointing directly in the direction of the massive star. The overall appearance of the Carina Nebula must have been quite different before the great eruption of η Car in 1841, which surrounded the star with dust, greatly reducing the ultraviolet radiation it poured into its environment. ·         Homunculus Nebula In the nebula,
there is a much smaller component that surrounds the star η Car. It was given the name of the Nebula of the Homunculus, from the Latin word homunculus which means little man. This bipolar cloud is believed to have been ejected from the star in a huge explosion in 1841 that briefly made η Because the second brightest star in the sky. The Homunculus Nebula is a small HII region containing shocked gases propelling them into either ionized or excited states. The Homunculus also absorbs much of the radiation from the extremely bright central star system and re-emits it in the infrared range. The Homunculus is the brightest object in the sky at mid-infrared wavelengths. ·         Keyhole Nebula This nebula has also been nicknamed the finger of God because of its resemblance to a middle finger. The keyhole, or keyhole nebula, is a small dark cloud of cold molecules and dust in the Carina Nebula. It also contains shiny filaments of hot, fluorescent gas cutting out on the much brighter background nebula.  The diameter of the keyhole structure is about seven light-years. Its appearance has changed considerably since its first observation, probably due to changes in the ionizing radiation of η CaR. ·         Trumpler 14
Trumpler 14 is an open cluster six light-years (1.8 pc) in diameter located in the interior regions of the Carina Nebula, about 2,733 pc (8,900 light-years) from Earth. It is one of the main clusters of the Carina OB1 stellar association, the largest association of the Carina Nebula.[11] This cluster is very young, about 6.8 million years old.[9] About 2,000 stars have been identified in Trumpler 14[18] and the total mass of the cluster is estimated at 4300 M. ·         Trumpler 15
Trumpler 15 is a star cluster located northeast of the Carina Nebula. Early studies disagreed on its distance, but astrometric measurements made by the Gaia mission confirmed that it was a distance comparable to the rest of the Carina OB1 association.[4] According to the WEBDA database, Trumpler 15 is 1,853 pc from Earth, about 6,044 light-years away and its age is 8.4 million years. ·         Trumpler 16
Trumpler 16 is one of the main clusters of the Carina OB1 star association and it is larger and more massive than Trumpler 14.[11] The star η Car is part of this cluster. According to the WEBDA database, Trumpler 16 is 2,673 pc from Earth, about 8,718 light-years away and its age is 6.1 million years.  ·         Mystical Mountain
The Mystical Mountain is a nickname given to a pillar of dust and gas that the Hubble Space Telescope photographed to celebrate its 20th anniversary.   ·         WR 22
WR 22 is a binary eclipse star system whose massive star is Wolf-Rayet and the smallest O type. The orbital data collected made it possible to calculate the masses of the two stars in the system: 55.3 ± 7.3 M the most massive star and 20.6 ± 1.7 M for the smallest. ·         WR 25
WR 25 is a binary system located in the central part of the Carina Nebula. This star system is part of the Trumpler 16 cluster. The most massive main star is wolf–rayet. It is perhaps the brightest star in the galaxy. The smallest secondary is difficult to observe, but it is thought to be an OB-type star.  ·         HD 93129
HD is a star system consisting of three O-type stars. The three stars of HD 93129 are among the brightest in the Milky Way.[23] HD 93129 consists of two clearly resolved components: HD 93129 A and HD 93129. HD 93129 A is itself a binary system whose two stars are much closer together. ·         HD 93250
HD 93250 is one of the brightest stars in the Carina Nebula. It is known to be a binary star, but the individual spectra of the two components have never been observed. The system is only 7.5 arc minutes away from η Car. HD 93250 is considered part of the Trumpler 16 cluster, although it seems closer to Trumpler 14.  ·         HD 93205
HD 93205 is a two-star binary system of the main sequence. The most massive star is of type 03.5. Its mass was calculated from the orbital parameters of the orbits. It is between 40 and 60 M. The least massive star is type 08 and its mass is about 20 M. It moves very quickly in its orbit at a speed of more than 300 km / s.  ·         Catalog of open clusters of NGC 3372 In 1998, there were 8 known open clusters in the Carina Nebula[2]: o   Bochum 10 (Bo 10) ;o   Bochum 11 (Bo 11) ;o   Collinder 228 (Cr 228) ;o   Collinder 232 (Cr 232) ;o   Collinder 234 (Cr 234) ;o   Trumpler 14 (Tr 14, Cr 230) ;o   Trumpler 15 (Tr 15, Cr 231) ;o   Trumpler 16 (Tr 16, Cr 233). ·         At the south of the Image
In what’s called the south pillars (of Carina) the most notable from Hubble space telescope image is HH666 it takes up most of the right side of the image and is quite faint and seemingly shadowed from the foreground gasses. The rest of these pillars have no names that I can find, and there are a lot of them.
See if you can find them.  The Seahorse Pillar, The Cat-a-pillar, Knifes Edge Pillar, Twin Peaks Pillars, The Tiny Pillar, The Beehive Pillar, Twin Pillars, Shady Mountain Pillars…
