Crowdsourcing Astronomical Definitions

What is a Galaxy? Cast Your Vote Here
“Our aim here is to promote further discussion of how to define a galaxy and, in particular, what separates it from a star cluster. Like most previous definitions, we adopt the requirement of a gravitationally bound stellar system as a minimum … we give our favoured criteria, and in the spirit of a ‘collective wisdom’, invite readers to vote on their preferred definition of a galaxy via a dedicated website. … In order to capture the thoughts of a wider audience about how to define a galaxy, we invite readers to vote. This ‘collective wisdom’ or ‘crowd-sourcing’ will be captured in an online poll. The poll allows one to choose the single best criterion or multiple criteria. Results of the poll will be reported from time to time at future astronomy conferences.”
