Explanation:
It's easy to get lost following the intricate strands of the Spaghetti Nebula.
A supernova remnant cataloged as Simeis 147 and Sh2-240, the glowing gas filaments
cover nearly 3 degrees -- 6 full moons -- on the sky.
That's about 150
light-years at
the stellar debris cloud's estimated distance of 3,000 light-years.
This sharp composite includes image data taken through
a narrow-band filter to highlight emission from hydrogen atoms
tracing the shocked, glowing gas.
The supernova remnant has an estimated age of about 40,000
years, meaning light from the massive
stellar explosion first
reached Earth about
40,000 years ago.
But the expanding remnant is not the only
aftermath.
The cosmic catastrophe
also left behind
a spinning neutron star or pulsar,
all that remains of the original star's core.
