NGC 1097: Spiral Galaxy with a Central Eye
Explanation:
What's happening at the center of spiral galaxy NGC 1097?
No one is sure, but it likely involves a
supermassive black hole.
Matter
falling in from a
bar of stars and gas across the center is likely being
heated by an extremely energetic region surrounding the
central black hole.
From afar, the entire central region appears in the
above false-color
infrared image as a
mysterious eye.
Near the left edge and seen in blue, a smaller
companion galaxy
is wrapped in the spectacular spiral arms of the large spiral, lit in pink by glowing
dust.
Currently about 40 thousand
light-years from the larger galaxy's center,
the gravity of the companion galaxy appears to be reshaping the
larger galaxy as it is slowly being destroyed itself.
NGC 1097 is located about 50 million light years away
toward the constellation of the furnace
(
Fornax).

An APOD editor will review great space images this Saturday night at Ft. Wilkins,
Michigan.
