Explanation: Star cluster NGC 346 is embedded in the largest star forming region in the Small Magellanic Cloud, some 210,000 light-years distant. The massive stars of NGC 346 are short lived, but very energetic. Their winds and radiation sweep out an interstellar cavern in the gas and dust cloud about 200 light-years across, triggering star formation and sculpting the region's dense inner edge. Cataloged as N66, the star forming region also appears to contain a large population of infant stars. A mere 3 to 5 million years old and not yet burning hydrogen in their cores, the infant stars are strewn about the embedded star cluster. In the false-color Hubble Space Telescope image, visible and near-infrared light are seen as blue and green, while light from atomic hydrogen emission is red.
Response to above: The core of a star in my opinion does no burn hydrogen. The highly dense plasma slowly releases new form hydrogen that fuses creating the secondary burn on the surface. The creation of the core can have many origins (1) matter collecting and tranforming into high dense plasma or (2) by a blackhole ejecting the high dense plasma. Plus other means. The life span will depend on the size of the core.
