    [page 254] The extensive investigations of extragalactic systems during recent years have brought to light the remarkable fact that there exist two well-defined types of new stars or novae which might be distinguished as common novae and super-novae. […] [page 255] Regarding the initial states of super-novae only the following meager facts are known. First, super-novae occur not only in the blurred central parts of nebulae but also in the spiral arms, which in certain cases are clearly resolved into individual stars. Secondly, the super-nova of 1572 in its initial stage probably was not brighter than apparent magnitude 5 as otherwise it would be registered as such in the old catalogues, which, however, is not the case. Super-novae are a much less frequent phenomenon than common novae. So far as the present observational evidence goes, their frequency is of the order of one super-nova per stellar system (nebula) per several centuries.

    Supernovas are clearly incredible objects of astoundingly explosive character. Were it possible for our Sun to go supernova, it would vaporize every planet in the solar system by the time it had reached peak brilliance. Were it possible for Alpha Centauri, which is only 1.3 parsecs away, to go supernova, it would blaze in our day and night sky with a brightness that, at maximum, would be 15,500 times that of the full Moon, or about one-thirtieth that of the Sun.

From super- (prefix meaning ‘exceptionally large in quantity, excessive; superior in potency or power’) + nova (“sudden brightening of a previously inconspicuous star”), coined by the German astronomer Walter Baade (1893–1960) and the Swiss astronomer Fritz Zwicky (1898–1974) who introduced the term in an astrophysics course and in seminars at the California Institute of Technology in 1931, although it was the Swedish astronomer Knut Lundmark (1889–1958) who first used the word in print in a paper dated 31 December 1932 and published in 1933: see the quotation.
