One of the most massive stars in the universe at more than 100 solar masses.
Situated in the star forming nebula NGC 3372, called the Great Carina Nebula, or the Eta Carinae Nebula.
One of the largest panoramic images ever taken with Hubble shows a 50 light-year-wide view of the central region of the Carina Nebula.
The stars giant mass makes Eta Carinae highly unstable, and prone to violent outbursts! The last of which occurred between 1835 and 1855 when Eta Carinae temporally became the second brightest star with an apparent magnitude -1.
