Field Guide to the Night Sky

Into the night
Seemingly empty space
Diminishing crescents
Move relative to one another
Arms that are increasingly spread
Intimately involved with the bodies
Physically connected
Mutual gravitational forces
To explore them in more detail
Stars, a handful of stars
Generations of stars
Edge of brightness
How bright it appears to us.

-These are phrases taken from the National Audubon Society Field Guide to the Night Sky  pub 1991 to create a cento, a poem of passages taken from another source and rearranged into a new work for the DVerse prompt.
