4 syllables: Su, per, no, vae. Stress on no.
soo-pur-NOH-vee
/suːpɚˈnoʊviː/
Supernovae is pronounced soo-pur-NOH-vee (/suːpɚˈnoʊviː/). It has four syllables (Su-per-no-vae), with the stress on "no". Supernovae are extremely luminous stellar explosions marking the death of massive stars; they outshine entire galaxies for brief periods. The plural form refers to more than one such event. In astronomy contexts, the term is used as a technical noun, often in scientific writing and discussions of stellar evolution and cosmology.

How to Pronounce Supernovae
"Astronomers observed several supernovae in distant galaxies over the course of a year."
"The light from a recent supernovae outshone its host galaxy for weeks, allowing detailed study."
"Astronomical surveys catalog thousands of supernovae to understand stellar life cycles."
Pronounce as su-per-NO-vae with the final -ae pronounced as /iː/ or /aɪ/ depending on accent. A practical guide: US: /ˌsuː.pɚˈnoʊ.viː/; UK: /ˌsjuː.pəˈnəʊ.veɪ/ or /ˌsjuː.pəˈnəʊ.viː/; Pay attention to the stress on the syllable before the final -vae. Mouth: start with a light ‘s’ then a quick ‘oo’ sound, stress the second syllable 'no', finish with a long ‘ee’ or ‘ay’ depending on dialect. Audio reference: you can listen to a pronunciation sample on Forvo or YouGlish by searching “supernovae.”
Common errors: (1) Stress misplacement, saying su-PER-no-vae; (2) mispronouncing the final -ae as a generic ‘a’ or ‘e’ instead of the long /iː/ or /aɪ/; (3) truncating the middle syllable, saying ‘super-nova’ as if plural is the same as ‘supernova’. Correction: keep the primary stress on the third syllable and articulate the final -vae clearly as /viː/ (US) or /veɪ/ (UK). Use minimal pairs and slow practice to secure the vowel quality of the final syllable.
In US English, you’ll hear /ˌsuː.pɚˈnoʊ.viː/ with rhoticity and a long o in the stressed syllable. UK English often uses /ˌsjuː.pəˈnəʊ.veɪ/ or /ˌsjuː.pəˈnəʊ.viː/ with non-rhoticity and a clear /əʊ/ in the second syllable; final -ae can be /eɪ/ or /iː/. Australian English tends toward /ˌsjuː.pəˈnɔː.viː/ with a more fronted vowel in some speakers and similar non-rhotic tendencies as UK. The main difference lies in vowels in the second and final syllables and the presence or absence of rhoticity in the first syllable.
It combines a stress shift across words and a non-obvious vowel sequence in the final syllable. The middle “nova” portion often carries variable stress in compound astronomical terms, and the suffix -ae yields different pronunciations (/iː/ vs /eɪ/ or /aɪ/). Additionally, the sequence /noʊ/ or /nəʊ/ followed by a high front vowel /iː/ or /eɪ/ demands careful place of articulation and careful lip rounding. Practicing with a mirror and recording helps solidify the intended vowel quality and rhythm.
The ending -ae, historically Latin, is pronounced as a distinct vowel group rather than a diphthongized single vowel in some varieties, often realized as /iː/ (US) or /eɪ/ (UK) depending on preference. Emphasize the two final sounds: the /noʊ/ or /nəʊ/ leading into the final /iː/ or /eɪ/. This creates a clean, elongated final syllable that differentiates 'supernovae' from the singular 'supernova'.

The term supernova derives from two components: the Latin prefix super- meaning ‘above, beyond’ or ‘more than’, and the noun nova, from the Latin novus meaning ‘new’, which was adopted in astronomy to describe a star that suddenly appears bright with a new light. The concept evolved in the 19th and early 20th centuries as astronomers observed stars that suddenly brightened and then faded, prompting the distinction between novae (lower-luminosity, recurrent) and supernovae (exceptionally bright, usually terminal). The plural form, supernovae, follows Latin pluralization with -ae, reflecting classical nomenclature used in star designations and early 20th-century astronomy literature. First use of the term “supernova” is typically traced to the 1930s, credited to Fritz Zwicky and Walter Baade, who popularized the distinction to classify these extraordinary stellar explosions. Over time, the term has encompassed various physically distinct mechanisms (Type I and II) and has become a cornerstone in cosmology for measuring vast distances and understanding the chemical enrichment of galaxies.
