1. supernovanoun

   A star which explodes, increasing its brightness to typically a billion times that of our sun, though attenuated by the great distance from our sun. Some leave only debris (Type I); others fade to invisibility as neutron stars (Type II).

   Etymology: super- + nova

1. Supernova

   A supernova is a stellar explosion that is more energetic than a nova. It is pronounced with the plural supernovae or supernovas. Supernovae are extremely luminous and cause a burst of radiation that often briefly outshines an entire galaxy, before fading from view over several weeks or months. During this short interval a supernova can radiate as much energy as the Sun is expected to emit over its entire life span. The explosion expels much or all of a star's material at a velocity of up to 30,000 km/s, driving a shock wave into the surrounding interstellar medium. This shock wave sweeps up an expanding shell of gas and dust called a supernova remnant. Nova means "new" in Latin, referring to what appears to be a very bright new star shining in the celestial sphere; 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. Supernovae can be triggered in one of two ways: by the sudden reignition of nuclear fusion in a degenerate star; or by the collapse of the core of a massive star. A degenerate white dwarf may accumulate sufficient material from a companion, either through accretion or via a merger, to raise its core temperature, ignite carbon fusion, and trigger runaway nuclear fusion, completely disrupting the star. The core of a massive star may undergo sudden gravitational collapse, releasing gravitational potential energy that can create a supernova explosion.

Examples of supernova in a Sentence

1. Deodatta V. Shenai-Khatkhate:

   Uno degli scrittori genio del 20 ° secolo, Hermann Hesse, premio Nobel e il mio autore preferito, ha scritto: "la maggior parte delle persone ... sono come una foglia che cade, che va alla deriva e si trasforma in aria, svolazza, e cade a terra ma. alcuni altri sono stelle come che percorrono un percorso definito: assenza di vento li raggiunge, hanno in se stessi la loro guida e il percorso ". Mi piace questa citazione, perché è così illuminante e potente. è anche un richiamo costante che tu sei la stella, e si deve mantenere il tuo personaggio - non importa ciò che gli altri dicono o fanno. inoltre non dimenticare che la stella ha ancora la capacità di trasformarsi in supernova, che illumina l'universo con una luce così potente che può venire solo da milioni di soli. Sempre cercare di essere quello splendente stella, e in ultima analisi supernova, per illuminare il mondo.

2. Andrea Dupree:

   No one knows how a star behaves in the weeks before it explodes, and there were some ominous predictions that Betelgeuse was ready to become a supernova, chances are, however, that it will not explode during our lifetime, but who knows ?

3. Daniel Wang:

   What we see in the picture is a violent or energetic ecosystem in our galaxy’s downtown, there are a lot of supernova remnants, black holes, and neutron stars there. Each X-ray dot or feature represents an energetic source, most of which are in the center.

4. Subo Dong:

   ASASSN-15lh is the most powerful supernova discovered in human history, the explosion’s mechanism and power source remain shrouded in mystery because all known theories meet serious challenges in explaining the immense amount of energy ASASSN-15lh has radiated.

5. Deodatta V. Shenai-Khatkhate:

   If only the ugly duckling had known her differentness would be an awesome asset some day, her earlier life would have been much smoother and enjoyable. We should be happy if we are different, because it's our differentiating differentness that will make a huge difference in the world and advance the humankind. You may be an ugly duckling today in the eyes of society, but you are the beautiful white swan of tomorrow. You are the Star today that will be Supernova tomorrow, illuminating and dazzling the universe as never before. Enjoy and celebrate your differentness today, and think positvely about tomorrow -always!
