The final act of some forgotten star,
Unleashes unseen light at breakneck speed;
And once these cosmic rays have journeyed far,
Into our atmosphere they start to bleed.
 
This energy from interstellar rays,
Is tempered by the Sun’s magnetic haze;
Creating nuclei from which clouds form,
A dying star can cause our Earth to warm.

This is a Heroic Rispetto, inspired by rec­­ent research which has shown how cosmic rays from supernovae can lead to the creation of clouds on Earth, and in doing so can influence our climate.
