While observing the heavens one night
My telescope put up a fight
A Globular Cluster
Was all it could muster
But oh what a marvellous sight!

Brings to mind Edna St Vincent Millay's:
My candle burns at both ends;
It will not last the night;
But ah, my foes, and oh, my friends--
It gives a lovely light!
Anyway, here's a limerick inspired by my meeting Hanny at the Greenwich picnic:
A newbie from Limburg called Hanny
(Inheriting brains from her granny)
On just her ninth dekko
Discovered an echo
Of light from a quasar — uncanny!
