What is a pea anyway?

  Can someone tell me what a pea is and how we spot one?

  Here's the wiki entry : https://en.wikipedia.org/wiki/Pea_galaxy

  Also peas are very small and round galaxies with a very high rate of starformation.

  Their spectrum is very characteristic: It is very flat with a huge OIII spike.

  And here is the original thread on the GZ forum that started it all : http://www.galaxyzooforum.org/index.php?topic=3638.0

  Enjoy ! 😄
