galaxy that have been discovered and recorded since 1891. Novae are stars that undergo dramatic explosions, but unlike supernovae, these do not result in the destruction of the original star. The likely rate of novae in the Milky Way is about 40 per year,Prialnik, Dina. "Novae", pp. 1846-56, in Paul Murdin, ed. ''Encyclopedia of Astronomy and Astrophysics.'' London: Institute of Physics Publishing Ltd and Nature Publishing Group, 2001. but of these only about 10 per year are discovered by observers as of the 2000s (decade).CBAT List of Novae in the Milky Way

Nomenclature

Novae are initially designated via a "Nova enitive form of constellation name ear of discovery format, e.g. "Nova Cygni 1974" and "Nova Scorpii 2010". An official permanent name is usually soon assigned by the
General Catalog of Variable Stars The General Catalogue of Variable Stars (GCVS) is a list of variable stars. Its first edition, containing 10,820 stars, was published in 1948 by the Academy of Sciences of the USSR and edited by B. V. Kukarkin and P. P. Parenago. Second and thi ...
using the GCVS format for the naming of variable stars. When more than one nova is discovered in a constellation in one year, a numeric suffix is appended; hence "Nova Sagittarii 2011 #2", "Nova Sagitarii 2011 #3", etc.
