The Senses of a Rocky Planet

Saturn’s rotating hurricane
It wears for hexagonal hat
Could swallow Earth four times over.

That’s every life that ever was,
Drop in one storm’s bucket of gas
On a nearby fellow planet.

Earth shivers and takes more pictures.
Some of Earth is building a new
Eye to fling out there to keep watch.

Earth’s working on ringed ears as well,
Just under its skin, to sense waves
So vast they could swallow the Sun.

Also, many more robot probes.
Earth can’t have enough robot probes.
What’s the metaphor for this? What?

Earth can only find tropes in itself,
Germ in a lab dish, spores adrift,
Deep sea lights, a cry in the night.
