Explanation: About 70 million light-years distant, gorgeous spiral galaxy NGC
289 is larger than our own Milky Way [6] . Seen nearly face-on, its bright
core and colorful central disk give way to remarkably faint, bluish spiral
arms. The extensive [7] arms sweep well over 100 thousand light-years from the
galaxy's center. At the lower right in this sharp, telescopic galaxy portrait
[8]  the main spiral arm seems to encounter [9]  a small, fuzzy elliptical
companion galaxy interacting with enormous NGC 289. Of course the spiky stars
are in the foreground of the scene. They lie within the Milky Way toward the
southern constellation Sculptor [10] .
