Carina Nebula

The Carina Nebula is one of the largest and brightest nebulae in the sky, spanning over 300 light-years and containing several of the most massive and luminous stars known. It is a dramatic region of ongoing star formation and destruction, located in the southern sky.

The nebula’s most famous resident is Eta Carinae — a hypergiant binary system containing a star estimated at 100–150 solar masses, one of the most massive known. In 1843 it briefly became the second-brightest star in the sky during a “Great Eruption” event, ejecting several solar masses of material that now form the visible Homunculus Nebula surrounding it.

The iconic “Mystic Mountain” structure, a towering pillar of gas and dust similar to the Pillars of Creation, was revealed by Hubble’s 20th anniversary image in 2010. Jets from young stars embedded within the pillar’s tip punch through the surrounding gas.

The Carina Nebula is a complex mixture of emission regions, reflection nebulae, dark absorption pillars, and open star clusters — a complete cross-section of stellar life cycles compressed into one field of view.
