Supernova: Difference between revisions

Revision as of 08:54, 6 May 2019

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
