NASA is released a new Hubble photo of a small portion of one of the largest known star-birth regions in the galaxy, the Carina Nebula surrounding several open clusters of stars dominated by Eta Carinae and HD 93129A, two of the most massive and luminous stars in our Milky Way galaxy at an estimated distance between 6,500 and 10,000 light years from Earth. Stars with more than 80 times the mass of the Sun, which are quite rare, produce more than a million times as much light as the Sun -only a few dozen in a galaxy as big as ours—and they skirt the edge of disaster near the Eddington limit, i.e., the outward pressure of their radiation is almost strong enough to counteract gravity, resulting in a possible supernova or hypernova.
