The Carina Nebula: Star Birth in the Extreme

Pictured here is a 50-light-year-wide view of the central region of the Carina Nebula where a maelstrom of star birth - and death - is taking place. This picture also considered as one of the largest panoramic images ever taken with Hubble’s cameras.

The immense nebula contains at least a dozen brilliant stars that are roughly estimated to be at least 50 to 100 times the mass of our Sun. The most unique and opulent inhabitant is the star Eta Carinae, at far left. Eta Carinae is in the final stages of its brief and eruptive lifespan, as evidenced by two billowing lobes of gas and dust that presage its upcoming explosion as a titanic supernova.

The fireworks in the Carina region started three million years ago when the nebula’s first generation of newborn stars condensed and ignited in the middle of a huge cloud of cold molecular hydrogen. Radiation from these stars carved out an expanding bubble of hot gas. The island-like clumps of dark clouds scattered across the nebula are nodules of dust and gas that are resisting being eaten away by photo ionization.

Assembled from 48 frames taken with Hubble Space Telescope’s Advanced Camera for Surveys, this image was taken in the light of neutral hydrogen. Color information was added with data taken at the Cerro Tololo Inter-American Observatory in Chile. Red corresponds to sulfur, green to hydrogen, and blue to oxygen emission.

NASA released this amazing picture on April 24, 2007 to celebrate the 17th anniversary of the launch and deployment of NASA’s Hubble Space Telescope.
