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.
