Explanation:
Normally faint and elusive, the Jellyfish Nebula is caught in
this alluring
scene.
In the telescopic field of view two bright yellowish stars,
Mu and
Eta
Geminorum, stand just below and above the Jellyfish Nebula at the left.
Cool red giants, they lie at the foot of the
celestial
twin.
The Jellyfish Nebula itself floats below and left of center, a bright 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 that 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.
Composed on April 30, this telescopic snapshot also captures Mars.
Now
wandering
through early evening skies,
the Red Planet also shines with a yellowish glow on the
right hand side of the field of view.
Of course, the Jellyfish Nebula is about 5,000 light-years away, while
Mars
is currently
almost 18 light-minutes from Earth.
