Poem: Alice Allen (apologies to William Blake)

Explanation:

Tycho! Tycho! burning bright
In the darkness of the night,
What exploding white dwarf star
Did frame thy remnant from afar,

In the distant deep dark skies
Under gaze of human eyes?
Seen by mortals and their ma
Named for one called Tycho Brahe.
