Supernova e hipernova
WebUna Supernova è una stella che esplode. L’esplosione di Supernova rappresenta l’ultimo atto, distruttivo e spettacolare, del ciclo evolutivo di stelle molto massive. Durante l’esplosione viene liberata un’energia enorme e la stella diventa così luminosa da splendere più di una intera galassia (Figura 1). http://www.astronomy.com/magazine/ask-astro/2024/03/ask-astro-what-are-the-differences-between-supernovae-kilonovae-and-hypernovae
