1. supernova(Noun)

   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. Todd Thompson:

   People are trying to understand supernova explosions, how supermassive black stars explode, how the elements were formed in supermassive stars, so if we could reveal a new population of black holes, it would tell us more about which stars explode, which don't, which form black holes, which form neutron stars. It opens up a new area of study.

2. Deodatta V. Shenai-Khatkhate:

   Une "zone de confort" représente le statu quo, à mon avis honnête, comme l'eau stagnante sombre dans un étang qui semble souvent si difficile de sortir de. Mais vous devez sortir de votre zone de confort, et traverser les frontières pour mieux vous-même, et être le meilleur. seulement en sortant de la sphère de votre zone de confort, vous serez en mesure d'explorer de nouveaux océans, et offrir à votre meilleur, quelque chose de beaucoup plus supérieure et magnifique que jamais, pour éclairer le monde ..... comme la brillance incroyable et magnifique luminosité d'une supernova, ou une étoile filante ou un météore même qu'ils quittent leur zone de confort et entrer dans de nouveaux territoires. efforcez de réinventer et vous renouveler à chaque étape de la vie, tout comme Madonna a fait pendant des années, et vous découvrirez vos nouveaux atouts, les pouvoirs impressionnants et beauté qui n'ont jamais été là avant. Oser sortir de votre zone de confort, parce que c'est exactement là où commence la vie réelle. Avoir une vie, mon ami.

3. Kae Hope Ranoa:

   ’Supernova’ is a big fuck you to everyone who was like, ‘Hey you're a chick but you're getting free beats and shit, what's going on?

4. 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!

5. Chris Pratt:

   This ups the ante for the last one in every way and shape you can imagine, it’s funnier, it moves faster, it’s richer, it has more dynamic stories, deeper emotional pull … we get to spend more time storytelling and less time giving expository backstory and origin story. It’s emotionally driven, character driven, relationship driven, epic space supernova that explodes and it’s bigger brighter faster than any movie you have ever seen.
