The spectacular NGC 1672

This spectacular image taken by the Hubble Space Telescope shows at a very high resolution the central region of NGC 1672, a barred spiral galaxy 60 million light years from Earth.

The galaxy's core, which most probably contains a supermassive black hole, is crossed by a yellow bar, composed of very old stars. Both ends of the rod spiral arms develop, of which only the initial portion is visible in this image.

The arms appear blue since this is the color of the newly formed young massive stars, while the pink/red dots scattered throughout the image are star-forming regions that appear this color due to the emission of hydrogen atoms.

Both the central area and the spiral arms are traversed by strips of dust. The latter appear dark in color as they absorb and block the light of the stars behind.
