What does supernova mean

A nova , despite its name, isn't actually a "new" star, but rather one that wasn't noticed until it exploded, when it may increase in brightness by a million times before returning to its previous state a few days later. A supernova is far larger; a star in its supernova state may emit a billion times as much light as previously. After a few weeks it begins to dim, until it eventually ceases to exist; it's often replaced by a black hole. Though remains that were shot out into space may survive; those of a great supernova seen in A.

All this may serve as a warning to those human stars whose fame explodes too rapidly; supernovas of this kind have sometimes vanished by the following year. These example sentences are selected automatically from various online news sources to reflect current usage of the word 'supernova.

Luma de Oliveira, they called him, after his supernova wife, whom he later divorced. Luma de Oliveira, they called him, after his supernova now ex- wife.

A large star in its death throes that suddenly explodes, increasing many thousands of times in brightness. New Word List Word List. 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. 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 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.

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? Deodatta V. Shenai-Khatkhate :. One of the genius writers of 20th century, Hermann Hesse, Nobel Laureate and my most favorite author, wrote: "Most people But a few others are like stars which travel one defined path: no wind reaches them, they have within themselves their guide and path.

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.

Since this is a new technique, we took extra steps to show that this method gives us reliable results, we showed that results from our technique match up with those from supernova measurements over the last 9 billion years, giving us confidence that our results are reliable at even earlier times.
