The tenth mission in their exploration

they came upon a nebula

which produced sound of such frequencies

on subspace radio like a song

for five nights, five days they scanned, recorded

the dark dusty cloud that slowly moved

particles closer, farther, gathering

dissolving, emitting, and strangely could not prove

if this cloud and song was the end of a star

the distinct remnant of supernova

or beginning of a new solar system

the dust to collapse, form a young cluster

as the ship flew around to take detailed readings

the crew all noticed the breadth and the size

their sensors detected it was not one cloud

but like the Eagle Nebula had regions comprised

of dust newly amassed, tall like a pillar

and dust newly dead, shot through the core

and hidden within the dust there was gathered

protostars spinning, gaining mass, accounting for

the sweet notes of the song, light like soprano

the low tones of the clouds, dark like a bass

the measured hum of their warp core, steady like an alto

against the deep and pure silence of black outer space

and in the middle was singing, high as their heartbeats

the thread of a tenor, the notes faint and trace

perhaps even imagined, for space has no sound which

is organized point, counterpoint, form, consonance

still this sound filled their system, five days and five nights

they listened while sleeping, eating, recovering

what the sound gave to each, who knows that answer

but the sound lighted through them like a mythical thing

at the end of five nights, they proceeded onward

their sense of space changed facing clouds of lightyears

the captain, he named it the Siren Nebula

and they flew away

free of grief

free of fear.
