We look at starshine, at distant starshine
From a main sequence F, G, or K.
We search for planets by solar transit,
Or the radial velocity way.
We once believed that our Sun was special.
Orbiting planets we thought were rare.
Then we discovered an exoplanet.
Now we look for them everywhere.
When Dedier Queloz and Michel Mayor
Announced in Florence fifty-one Peg,
We knew at last that planets are common,
But a bigger question they beg.
We've now detected several hundred.
They bring us knowledge of major worth.
Still, we are trying to discover:
Are there any out there like Earth?
We think we've found one with liquid water,
Though it is yet to be clearly shown
That other worlds host life abundant,
So we still ask: Are We Alone?
