Once upon a time, the rainbow’s end
Is where a leprechaun would hide his gold
Then Newton showed us how a glass would bend
A beam of light—a rainbow we behold!

This bending light is what allows, today,
A view of distant galaxies and more
The start of time itself is on display
And lifetimes’ worth of treasures to explore.

These treasures, it now seems, include real jewels
When quasar jets spit rubies and sapphires;
From Newton’s prism, oh what wondrous tools
Expose a treasure passing all desires

The rainbow’s gold’s forgotten; this is real:
A myth discarded, treasures may reveal!
