Supernova are sudden cataclysmic events that happen within seconds. They are rare events and that is one reason that they are so little understood.
Supernova remnants can be viewed, such as the crab nebula, but to view an actual supernova in progress is almost impossible to predict.
The most likely object to go supernova in our lifetime is Betelgeuse but there may well be others that will explode before then.
Supernovas are the explosions of large stars in space.
Massive stars, typically with a mass greater than 8 times that of our Sun, explode in a type II supernova. These stars undergo a core collapse followed by a massive explosion, resulting in the release of vast amounts of energy and debris into space.
No, they are much smaller.
The explosions of supernovas
No, you should not be worried about supernovas. While they are powerful explosions of dying stars, they are typically far enough away from Earth to pose any direct threat to us.
gases.
binary stars are two stars that orbit each other while supernovas and novas stars are stars that explode when it runs out of fuel

no
Stars do not create supernovas. Supernovas happen to stars. A supernova is when a star, bigger than our own sun, explodes due to the lack of gas they need.
They are not. A supernova is an explosion of a star. Blue stars usually end their lives in such explosions.
Star Dust from supernovas is what makes technically 'everything' in the Universe.
In space.
A great energy and light is produced by the supernovas. Therefore, a great number of photons is produced.
Yes.
No. Supernovas are cataclysmic eruptions from massive stars that have come to the end of their lives. See related questions
