These delicate filaments are actually sheets of debris from a stellar explosion in a neighboring galaxy, the Large Magellanic Cloud (LMC), a small companion galaxy to the Milky Way visible from the southern hemisphere. This remnant, know as N49 or DEM L 190, is from a massive star that died in a supernova blast thousands of years ago. This filamentary material will eventually be recycled into building new generations of stars in the LMC. Our own Sun and planets were formed from similar debris of supernovae that exploded in our own galaxy billions of years ago.
These filaments harbor a very powerful spinning neutron star that may be the central remnant from the supernova. It is quite common for the core of an exploded supernova star to become a spinning neutron star (or pulsar) after the immediate shedding of the supernova’s outer layers. The pulsar in N 49 is spinning at a rate of once every 8 seconds. It also has a super-strong magnetic field a thousand trillion times stronger than Earth’s magnetic field. This places this star into the exclusive class of objects called “magnetars.”

The Magnetars are gonna’ get their team logo banned.
