Explanation:
Distorted galaxy NGC 2442 can be found in the southern constellation of the
flying fish,
(Piscis) Volans.
Located about 50 million light-years away, the galaxy's two
spiral arms extending from a pronounced central bar have a hook-like
appearance in wide-field images.
But this
mosaicked close-up, constructed from
Hubble Space Telescope and
European Southern Observatory
data, follows the galaxy's structure in
amazing detail.
Obscuring dust lanes, young blue star clusters and
reddish star forming regions
surround a core of yellowish light from an older population of
stars.
The sharp image data also reveal more distant
background galaxies seen right through NGC 2442's
star clusters and nebulae.
The image spans about 75,000
light-years
at the estimated distance
of NGC 2442.
