Creating Earth and Moon #poem #poetry #space #Moon #solarsystem


Did Theia and proto Earth’s mantle vaporize and merge?

Terrestrial and lunar rocks
Share similarities,
The isotopes of elements
Found in both of these.

Early in the solar system,
When proto-worlds collide,
Such isotopic matching
Is hard to reconcile.

New research seeks a better scheme
And everyone is trying,
Potassium in rocks may show
Which models are complying.

Perhaps the rogue colliding spheres
Vaporized Earth’s mantle
To atmospheres of gaseous rock,
Of fluids supercritical.

Then Earth and Moon, upon their face,
Would match in just this way.
Their composition now makes sense
At least, it does today.

R&R 3 coversThanks to for their article on the birth of the Moon, and to Kun Wang (Washington University) and Stein Jacobsen (Harvard) for their findings online September 12 in the journal Nature. The Mars-sized rock that collided with Earth is called Theia, named for the mother of the Moon in Greek myth, but I just couldn’t work that into the poem :\ Why don’t you give it a try?
