HUBBLE SERVES UP A GALAXY

What may first appear as a sunny side up egg is actually NASA Hubble
Space Telescope's face-on snapshot of the small spiral galaxy NGC 7742.
But NGC 7742 is not a run-of-the-mill spiral galaxy. In fact, this
spiral is known to be a Seyfert 2 active galaxy, a type of galaxy that
is probably powered by a black hole residing in its core. The core of
NGC 7742 is the large yellow "yolk" in the center of the image. The
lumpy, thick ring around this core is an area of active starbirth. The
ring is about 3,000 light-years from the core. Tightly wound spiral arms
also are faintly visible. Surrounding the inner ring is a wispy band of
material, which is probably the remains of a once very active stellar
breeding ground.
