English language haiku are characterized by 5-7-5 syllable pattern in 3 lines.
Characterized by brevity in thought and function, cliche avoidance though historical or lyrical reference acceptable. Haiku derives from cutting as with a blade where the verbs separate descriptions (of nature). Rhymes are accidental, punctuation minimal.
Curium IIRC was named after Marie and Peter Curie who discovered Radium. If memory serves, Marie succumbed to radiation poisoning (line 1, "glows"); Peter died after being struck by a carriage or cart in the street (line 2, "crushed by momentum"). Marie Curie represents early female scientists and researchers (line 3, "remembered in STEM").
This haiku carries 2-3 references to natural science replacing nature in traditional Haiku.
