Scattered debris from a cosmic supernova explosion
lights up the sky
in this gorgeous
composited image based on data from the Hubble Space Telescope. Cataloged as N49, these glowing filaments of shocked gas
span about
30 light-years in our neighboring galaxy, the
Large Magellanic Cloud. Light from the original exploding star reached Earth thousands of years ago, but N49 also marks the location of another energetic outburst -- an extremely intense blast of
gamma-rays detected by satellites on
March 5, 1979. That date was the beginning of an
exciting journey in astrophysics
which led researchers to the understanding of an exotic new class of stars. The source of the "March 5th Event" is now attributed to
a
magnetar - a highly magnetized, spinning neutron star also born in the ancient stellar explosion which created supernova remnant N49.
The
magnetar hurtles through the supernova
debris cloud at over 1,200 kilometers
per second.
