Apr 26th, 2016: Spaghetti Nebula

[xoxoxoBruce]

The Spaghetti Nebula, or Supernova Remnant Simeis 147 and Sh2-240, if you want to get picky.

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.

I'd explain all that but suddenly I'm real hungry... for pasta.
