Explanation:
Normally faint and elusive, the Jellyfish Nebula is caught in
this alluring telescopic image.
Centered in the scene it's anchored right and left by two bright stars,
Mu
and
Eta
Geminorum, at the foot of the
celestial
twin.
The Jellyfish Nebula is the brighter arcing
ridge of emission with dangling tentacles.
In fact, the cosmic jellyfish is 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, the Jellyfish Nebula is
known
to harbor a neutron star, the remnant of the collapsed stellar core.
An emission nebula cataloged as
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 about 300 light-years across.
