η Carinae (Eta Carinae, abbreviated to η Car), formerly known as η Argus, is a stellar system containing at least two stars with a combined luminosity greater than five million times that of the Sun, located around 7,500 light-years (2,300 parsecs) distant in the constellation Carina.
To match those observations, the models require much higher mass loss rates. Eta Carinae A has one of the highest known mass loss rates, currently around 10 −3 M ☉ /year, and is an obvious candidate for study. [95] Eta Carinae A is losing so much mass due to its extreme luminosity and relatively low surface gravity.
HD 93205, or V560 Carinae, is a binary stellar system, in the Carina Nebula (NGC 3372) in the constellation Carina. It consists of two massive O-stars that revolve around each other in 6 days . The more massive member of the pair is an O3.5 main sequence star.
The Cosmic Cliffs at the edge of NGC 3324, one of the first images taken by the James Webb Space Telescope. The Carina Nebula [7] or Eta Carinae Nebula [8] (catalogued as NGC 3372; also known as the Great Carina Nebula [9]) is a large, complex area of bright and dark nebulosity in the constellation Carina, located in the Carina–Sagittarius Arm of the Milky Way galaxy.
HR Carinae is a lot like Eta Carinae, both luminous blue variables, and both surrounded by ejected material. HR Carinae is also likely to be a binary system with a similar separation, period, and ratio of component sizes to Eta Carinae. [22] However, the Eta Carinae system is more massive and more luminous.
The average cloud weighs over one million pounds. Wearing a necktie could reduce blood flow to your brain by up to 7.5 percent. Animals can also be allergic to humans.

It is also designated α Carinae, which is romanized (transliterated) to Alpha Carinae. With a visual apparent magnitude of −0.74, it is outshone only by Sirius . Located around 310 light-years from the Sun , Canopus is a bright giant of spectral type A9 , so it is essentially white when seen with the naked eye.
