Breaking News: The Galaxy is Rich in Small, Rocky, Earth-Sized Planets!

This really is breaking news.  More than 100 planets that are a similar size to Earth have been discovered in the past few weeks,

I have just been looking at a TED talk by a chap called Dimitar Sasselov, who announced this.  The Kepler telescope is being used to discover small planets around stars in the local region of the galaxy (a sphere with a diameter of 100 light years).  They reckon that there may be 100 million small rocky planets in the galaxy altogether.

Definitely another Copernican revolution in the offing.  I daresay we are being visited by some of our neighbours already!
