Supernova

• Massive stellar explosion occurring at the end of a star's natural life cycle due to fusion pressure no longer able to balance against gravitational core collapse
  • Results in a stellar remnant in the form of either a neutron star or a black hole
• Resulting explosion produces a wavefront of intense radiation, devastating planetary ecosystems within 25-50 ly
  • Often also results in a surrounding micronebula, or even full nebula
