Several X-ray and gamma ray sources have been detected around η Carinae, for example 4U 1037–60 in the 4th Uhuru catalogue and 1044–59 in the HEAO-2 catalog. The earliest detection of X-rays in the η Carinae region was from the Terrier-Sandhawk rocket, [66] followed by Ariel 5, [67] OSO 8, [68] and Uhuru [69] sightings.
Detailed look on Eta Carinae. Carina Nebula (left), Homunculus Nebula (center), and high resolution image of Eta Carinae (right). [10] Each lobe has polar "hole" although it is not known whether it is an actual gap in the shell of the lobe or just a deep indentation. Surrounding each polar hole is a "trench".
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.

Trumpler 16 (Tr 16) is a massive open cluster that is home to some of the most luminous stars in the Milky Way galaxy. It is situated within the Carina Nebula complex in the Carina–Sagittarius Arm, located approximately 9,270 ly (2,842 pc) from Earth. [1]
Possible examples of supernova impostors include the Great Eruption of Eta Carinae, P Cygni, SN 1961V, [3] SN 1954J, SN 1997bs, SN 2008S in NGC 6946, and SN 2010dn [1] where detections of the surviving progenitor stars are claimed.
HD 93129 is a triple star system in the Carina Nebula, with all three components being hot O class stars amongst the most luminous stars in the Milky Way.It is the dominant member of the Trumpler 14 star cluster, a young star cluster within the Carina OB1 stellar association that harbors other super-luminous stars, like Eta Carinae and WR 25.
One of the most massive stars known is Eta Carinae, [4] with 100–200 M ☉; its lifespan is very short—only several million years at most.A study of the Arches Cluster suggests that 150 M ☉ is the upper limit for stars in the current era of the universe.
