Hubble’s Advanced Camera for Surveys shows individual stars, clusters of stars and nebulae in the spiral galaxy NGC 300, located approximately 7 million light-years away from Earth. The image shows a star-forming region a few thousand light-years farther from the galaxy’s centre. The yellow nebulosities are the glow from hot gas that has been heated by radiation from the nearest young, blue stars. The image at far right reveals more diffuse groupings of young, blue stars, farther away from the galaxy’s centre, along with faint shells of hot gas.
