Bonus Bonus Bonus Sonnet Dare: In Which I Ponder Habitable Exoplanets

In March the Kepler probe began to seek
The subtle signs of planets far in space
That circle other stars. Is Earth unique
As an abode for life like ours? This place
Which some believe's created just for us
Might not be all that special, all that rare.
But then I ponder on Copernicus,
Who laid the Ptolemaic theory bare
And proved to all the Earth goes round the sun.
It took hundreds of years before some folk
Accepted this, unbanned his book and one
Suspects that out there still, like some great joke
Are people who'll insist his work's all lies
And exoplanets naught but fireflies.
