A book is a set of written, printed, illustrated, or blank sheets, made of ink, paper, parchment, or other materials, fastened together to hinge at one side. A single sheet within a book is a leaf, and each side of a leaf is a page. A set of text-filled or illustrated pages produced in electronic format is known as an electronic book, or e-book.
Books may also refer to works of literature, or a main division of such a work. In library and information science, a book is called a monograph, to distinguish it from serial periodicals such as magazines, journals or newspapers. The body of all written works including books is literature. In novels and sometimes other types of books (for example, biographies), a book may be divided into several large sections, also called books (Book 1, Book 2, Book 3, and so on). An avid reader of books is a bibliophile or colloquially, bookworm.
A shop where books are bought and sold is a bookshop or bookstore. Books can also be borrowed from libraries. Google has estimated that as of 2010, approximately 130,000,000 unique titles had been published. In some wealthier nations, printed books are giving way to the usage of electronic or e-books, though sales of e-books declined in the first half of 2015.
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.

The following week it rose to number four, and peaked at number two. It performed even better in Hudson's native United Kingdom, where it debuted at number two on the UK Singles Chart on 26 July 2009 (for the week ending date 1 August 2009)
