Spiral Galaxy NGC 7742
Explanation:
This
might resemble a fried egg you've had
for breakfast, but it's
actually much larger.
In fact, ringed by blue-tinted
star forming regions and
faintly visible
spiral arms,
the yolk-yellow center of this face-on spiral galaxy,
NGC 7742, is about 3,000 light-years across.
About 72 million
light-years away in the
constellation Pegasus,
NGC 7742 is known to be
a Seyfert galaxy - a type of
active spiral galaxy with a center or
nucleus which is very bright
at
visible wavelengths.
Across the spectrum,
the
tremendous brightness of
Seyferts can change over periods of
just days to months and galaxies like NGC 7742 are
suspected of harboring
massive
black holes at their cores.
