Explanation:
Beautiful and bright
spiral galaxy M83
lies a some twelve million light-years away, near the southeastern
tip of the very long constellation
Hydra.
Prominent spiral arms traced by dark dust lanes and blue star
clusters lend this galaxy its popular name, The Southern Pinwheel.
Still, reddish
star forming regions
that dot this cosmic pinwheel's spiral arms
have suggested another nickname, the
Thousand-Ruby Galaxy.
A mere 40,000 light-years across, smaller than the Milky Way,
M83 is a member of a group of galaxies that includes active galaxy
Centaurus A.
In fact, the core of M83 itself is bright
at x-ray energies, showing a high
concentration of neutron stars and black holes left from
an intense burst of star formation.
This sharp color image
also features spiky
foreground Milky Way stars and distant background
galaxies.
The image data was captured with the
Dark Energy Camera
and Blanco 4-meter telescope at Cerro Tololo
Inter-American Observatory.
