could someone please tell me

of the moons intentions

and of their affair

with Jupiter's rings

when lo and behold

Io has a fire in her belly

snowy volcanic fields

burning ice in her spring

Europa stands by

displaying cold shoulders

with oceans below

life she does bring

brother Ganymede

pulls it together

dark are his regions

light his terrain

beaten and battered

Callisto the stepchild

unchanged in its matter

and the song that it sings

is this all true

of Jupiter's moons

and of their intentions

could someone tell me
