Explanation:
About 70,000 light-years across,
NGC 247
is a spiral galaxy smaller than our Milky Way.
Measured to be
only 11 million light-years distant it is nearby though.
Tilted nearly edge-on as seen
from
our perspective,
it dominates this telescopic field of view toward the
southern constellation Cetus.
The pronounced void on one side of the galaxy's disk recalls
for some its popular name, the Needle's Eye galaxy.
Many background galaxies are visible in
this sharp galaxy portrait,
including the remarkable string of four galaxies
just below and left of NGC 247 known as Burbidge's Chain.
Burbidge's
Chain galaxies
are about 300 million light-years distant.
NGC 247 itself is part of the Sculptor Group of galaxies along with
shiny spiral NGC 253.
