Eta Carinae Nebula is a complex of bright and dark nebulae estimated to lie at 6,500 to 10,000 light-years from earth in the Carina-Sagittarius arm of our galaxy. A very extensive, but diffuse, nebula, it hosts the brightest known star in our galaxy: WR 25 (a Wolf-Rayet star). The nebula is larger than the well-known Orion Nebula, but its greater distance makes it appear less spectacular.
