Emission Nebula

It’s a pretty monster, cross
Between one of Blake’s angels,
Hair swept out by stellar winds,

And a root vegetable
Or enormous ocean comb
Drifting slowly through deep space,

The earliest recorded
Supernova, known so far,
Or its faint remnants.

The shock wave’s still expanding
From the white dwarf ripped apart.
That which is not evident

But for which the evident
Holds clues is significant,
Is numinous, is meaning.
