Superluminous supernova

A superluminous supernova (SLSN, plural superluminous supernovae or SLSNe), also known as a hypernova, is a type of stellar explosion with a luminosity 10 or more times higher than that of standard supernovae. Like supernovae, SLSNe seem to be produced by several different mechanisms, which is readily revealed by their light-curves and spectra. There are multiple models for what conditions may produce an SLSN, including core collapse in particularly massive stars, millisecond magnetars, interaction with circumstellar material (CSM model), or pair-instability supernovae.

What is Sussle?

Sussle is the first, open visual encyclopedia. Anyone can use it.

What's a visual encylopedia?

It has beautiful images and viral videos that are way more fun than reading all the text in traditional encyclopedias.

5 reasons you should add your own images and videos:

  1. If you found Sussle interesting, then give back by adding something interesting for others.
  2. Help others learn in a fun way.
  3. Make someone else interested in this topic laugh or say wow!
