Good old XKCD, they never fail to both amuse, educate and amaze (I’m sure Lord Reith would have approved.  Well, maybe…)

Today they’ve created this wonderful picture of every exoplanet so far discovered, all 786 of them – did you know there were that many?  Up until very recently there were NO known planets outside of our solar system and our chances of actually discovering any were thought to be very very poor indeed.

It may not be scientifically rigourous, but it says more than any spreadsheet ever could. (click on the image to see a full-size version).

I wonder how much bigger this diagram will be in a few years’ time… 🙂
