Sample size >>1

A few years ago we had not identified a single planet outside our solar system. Today the estimate is up to 100,000,000,000 (give or take a few). In fact the study of exoplanets is hot stuff at the moment with Nature papers generating headlines about exoplanets both yesterday and today.

Here's today's paper from Nature:
One or more bound planets per Milky Way star from microlensing observations
and one, of many, news reports - this one from the BBC: More planets than stars?

Yesterday's paper was about the recent discovery of several new planets that orbit multiple suns,
Transiting circumbinary planets Kepler-34 b and Kepler-35 b.
Was there a press report that didn't mention Tatooine? Real-Life Tatooine: Planets With Two Suns Found
