The Keyhole Nebula (NGC 3324), a bright structure just below the center of the image, contains several massive stars. The entire Great Carina Nebula shown here spans more than 300 light-years and is about 7,500 light-years away in the direction of the constellation Carina. Eta Carinae (Eta Carinae) is the most active star in the nebula and was one of the brightest stars in the sky in the 1830s, but has since dimmed dramatically. Eta Carinae itself may be on the verge of an imminent supernova explosion, and X-ray images show that much of the Carina Nebula is a veritable supernova factory.
