ISM

A poem about the Interstellar Medium.

Solar System Portrait, “Earth as Pale Blue Dot” (source)

Infrared radiation penetrates deeply,
due to the low optical depth —
to penetrate in the depths of molecular clouds.
Far from thermodynamic equilibrium
[a few MeV]
hot stars chip away electrons from dust grains.
Imagine a supernova remnant
& its magnetohydrodynamic waves;
