  1. supernova(noun)

    a star that explodes and becomes extremely luminous in the process

Wiktionary

  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

Freebase

  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:

    One of the genius writers of 20th century, Hermann Hesse, Nobel Laureate and my most favorite author, wrote: "Most people...are like a falling leaf that drifts and turns in the air, flutters, and falls to the ground. But a few others are like stars which travel one defined path: no wind reaches them, they have within themselves their guide and path." I like this quote, because it is so enlightening and powerful. It's also a constant reminder that you are the Star, and you must maintain your character - no matter what others say or do. Also not to forget that the Star does have ability to turn into Supernova, which brightens the Universe with such a powerful light that can only come from millions of Suns. Always strive to be that shining Star, and ultimately Supernova, to illuminate the world.

  2. 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.

  3. 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.

  4. Deodatta V. Shenai-Khatkhate:

    A "Comfort Zone" represents status quo, in my honest view, like the stagnant dark water in a pond that often seems so difficult to come out of. Yet you have to step outside your comfort zone, and cross the boundaries to better yourself, and be the best. Only by stepping outside the realm of your comfort zone, you will be able to explore new oceans, and offer your best, something far more superior and beatiful than ever before, to illuminate the world.....like the amazing brilliance and beautiful brightness of a supernova, or a shooting star or even a meteor as they leave their comfort zone and enter into new territories. Strive to re-invent and renew yourself at every stage in life, just like Madonna has done for years, and you will discover your new strengths, awesome powers and asounding beauty that were never there before. Dare to step outside your comfort zone, because that's exactly where the real life begins. Get a Life, my friend.

  5. Brian Fields:

    When you see green bananas in Illinois, you know they are fresh, and you know they did not grow here, like bananas, Pu-244 and Sm-146 decay over time. So if we find these radioisotopes on Earth today, we know they are fresh and not from here -- the green bananas of the isotope world -- and thus the smoking guns of a nearby supernova.
