Carina Nebula

The Carina Nebula, also known as the Eta Carinae Nebula, is a massive, complex area of bright and dark nebulosity in the located in the constellation of Carina, located in the Milky Way's Carina-Sagittarius Arm. The nebula is about 8,500 light-years away from Earth. 
The expansive Carina OB1 association and several adjacent open clusters, containing a huge number of O-type stars and several Wolf-Rayet stars, are located within the borders of the nebula. The star clusters Trumpler 14 and Trumpler 16 are included in Carina OB1. With a half-million-year age, Trumpler 14 is one of the newest star clusters ever discovered. Together with the less bright but more famous Eta Carinae star system and the O2 supergiant HD 93129A, Trumpler 16 is the location of WR 25, currently the most luminous star known in our Milky Way galaxy. The organisation also includes Trumpler 15, Collinder 228, Collinder 232, NGC 3324, and NGC 3293 as members. The oldest and farthest object from Trumpler 14 is NGC 3293, which suggests that star production is continuous and sequential.
One of the biggest diffuse nebulae visible in our night sky is the nebula. The Carina Nebula is significantly less well known than the renowned Orion Nebula despite being four times larger and even brighter than it due to its location in the southern sky. Nicolas-Louis de Lacaille made the find in 1752 while travelling from the Cape of Good Hope.
The nebula hosts the famous bright star called Eta Carina which is a highly luminous hypergiant star with a mass around 100 to 150 ☉ masses
=== Homunculus Nebula ===
The Homunculus Nebula is a small H II region, with gas shocked into ionized and excited states. Within the large bright nebula is a much smaller feature, immediately surrounding Eta Carinae itself, known as the Homunculus Nebula (from Latin meaning Little Man). It is believed to have been ejected in an enormous outburst in 1841 which briefly made Eta Carinae the second-brightest star in the sky. 
=== Keyhole Nebula ===
The small dark cloud of cold molecules and dust known as the Keyhole Nebula is located inside the Carina Nebula. It may be differentiated from the background nebula, which is much brighter, by its brilliant of hot, bright gas. The Keyhole nebula has a diameter of around 13.05 ly. The Keyhole Nebula conceals a number of large star formations. Due to the strength of their cosmic winds, their activity continuously alters how the nebula itself appears.
