A supernova is a rare astronomical event that occurs during the last stellar evolutionary stages of a massive star's life, whose dramatic and catastrophic destruction is marked by one final titanic explosion. For a short time, this causes the sudden appearance of a 'new' bright star, before slowly fading from sight over several weeks or months.
Only three Milky Way naked-eye supernova events have been observed during the last thousand years, though many have been telescopically seen in other galaxies. The most recent directly observed supernova in the Milky Way was Kepler's Star of 1604 (SN 1604), but remnants of two more recent supernovae have been found retrospectively. Statistical observations of supernova in extragalactic galaxies suggest they should occur on average about three times every century in the Milky Way, and that any galactic supernova would almost certainly be observable in modern astronomical equipment.
Supernovae are more energetic than novae. In Latin, Nova means "new", referring astronomically to what appears to be a temporary new bright star. Adding the prefix "super-" distinguishes supernovae from ordinary novae, which are far less luminous. The word supernova was coined by Walter Baade and Fritz Zwicky in 1931. It is pronounced /ˌsuːpərnoʊvə/ with the plural supernovae /ˌsuːpərnoʊviː/ or supernovas (abbreviated SN, plural SNe after "supernovae").
Supernova were a Chilean pop band integrated by three girls and was created by Koko Stambuk and Cristian Heyne, influenced by American teen pop of the 90's.
Between 1999 and 2001, Supernova was integrated by Constanza "Coni" Lewin, Elisa Montes and Consuelo "Chi-K" Edwards, and from 2001 to 2003 by Claudia González, Constanza "Koni" Lüer and Sabina Odone. Both groups of girls only recorded one studio album, the first one was Supernova which sold 45,000 copies, and achieving Double Platinum, and the second was Retráctate this one was a Latin Grammy nominee for Best Pop Vocal Album, Duo or Group.
Several times the original group perdormed live on Blondie Discothèque and in 2010 the group returned for a mini tour.
