How Many Earths?

How Many Earths?Ever wondered how many stars in the night sky had planets like Earth going around them? That’s what my latest interactive feature for New Scientist is about. I built it with my colleagues Peter Aldhous and MacGregor Campbell, using data from the Kepler space telescope. Rather than taking up more space here, I’ll let the feature speak for itself; I hope you enjoy it as much as I do.
