unar Crater Radio Telescope
on the rugged far side nested in a slope,
after Arecibo, gives scientists hope.
Radio wavelengths longer than ten meters,
no ionosphere causing them to peter,
cosmic electromagnetic reader
record the radiation from the past
traveling parsecs from Dark Ages cast
from hydrogen redshift before stars amassed.
In Cosmic Dawn the heavens were lit,
and with stretched waves spacetime is writ—
state of the medium intergalactic.
