| Background |
Spiral galaxy NGC 253, also known as the Sculptor Galaxy or Silver Coin Galaxy, lies 10,000,000 light years away
in the Sculptor Group magnitude 8. The Sculptor group of galaxies are thought to be the closest group to our
local group of galaxies including such objects as our Milky Way, Andromeda Galaxy, Large and the Small
Magellanic Cloud, Triangulum Galaxy and several others.
The Sculptor Galaxy is a starburst galaxy. Like our own galaxy, intense star formation is taking place. Several
huge, bright globular clusters may be seen just outside and on the disk. The details in the spiral arms
illustrates how much matter is in this object.
