The BR S Novarosa takes its name from a rare and spectacular
astronomical event: the explosion of a star. This occurs when it
reaches the latter stages of its life. It starts shining very brightly before exploding in an enormous cloud of dust. The shock waves are big enough to encompass an entire galaxy, which typically contains around 100 billion stars. This extraordinary phenomenon can last several hours. It is estimated that the star releases the same amount of energy produced by the Sun over thousands of years. These supernovae are some of the brightest phenomena of the universe and only two or three occur each century. Despite such rare occurrence and the difficulty in observing them from the earth, they astound and amaze those who have the chance to witness them.
