This image taken by the Hubble Space Telescope shows a population of infant stars in the Milky Way’s satellite galaxy, the Small Magellanic Cloud, located 210,000 light-years away. Some of the stars in the nebula NGC 346 are still forming from gravitationally collapsing gas clouds, and they have not yet ignited their hydrogen fuel to sustain nuclear fusion. The smallest of these infant stars is only half the mass of the Sun.
