NGC 300

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.

NGC 253 Close Up

NGC 253 is one of brightest spiral galaxies in the night sky, easily visible with small telescopes, and it is composed of thousands of young, blue stars. It is undergoing intense star formation. The image demonstrates the sharp “eye” of Hubble’s Advanced Camera for Surveys, which is able to show individual stars. The dark filaments are clouds of dust and gas. NGC 253 is the dominant galaxy in the Sculptor Group of galaxies and it resides about 13 million light-years from Earth.
