An old favourite updated... From Violent Universe by Nigel Calder, 1969, BBC (book)
Instant Astronomy: circa 1969
Twinkle, twinkle, little star
We know exactly what you are:
Nuclear furnace in the sky,
You'll burn to ashes by and by.
But tick, tick, tick pulsating star,
Now we wonder what you are:
Making monkeys of us all!
And twinkle, twinkle, quasi-star,
You're the limit, yes you are:
With such indecent energy,
Did God not say you couldn't be?
