Explanation:
Normally faint and elusive, the Jellyfish Nebula is caught in
this
alluring wide-field telescopic view.
Flanked by two yellow-tinted stars,
Mu
and
Eta
Geminorum,
at the foot of a
celestial
twin,
the Jellyfish Nebula is the brighter arcing
ridge of emission with dangling tentacles right of center.
In fact, the cosmic jellyfish is seen to be part of bubble-shaped
supernova remnant IC 443, the expanding
debris cloud from a
massive
star that exploded.
Light from the explosion first reached planet Earth over 30,000 years ago.
Like its cousin in astrophysical waters the
Crab Nebula
supernova remnant, IC 443 is known to harbor
a neutron star, the remnant of the collapsed stellar core.
Emission nebula Sharpless 249 fills the field at the upper left.
The Jellyfish Nebula is about 5,000 light-years away.
At that distance, this image would be almost 200 light-years
across.
