   A supernova ( pl.: supernovae or supernovas) is a powerful and luminous explosion of a star. A supernova occurs during the last evolutionary stages of a massive star, or when a white dwarf is triggered into runaway nuclear fusion. The original object, called the progenitor, either collapses to a neutron star or black hole, or is completely ...

10. People also ask

    How often do supernovas occur?

    • Supernovae are extremely rare – occurring only once every fifty years within a galaxy the size of our own Milky Way. They can only happen when an aging massive star can no longer generate energy from nuclear fusion and undergoes a rapid gravitational collapse.

    What are the consequences of a supernova?

    • When a supernova occurs the explosion results in the formation of elements such as gold and uranium. This is due to the extremely high temperatures (in the millions of degrees). Supernovas are responsible for the elements such as oxygen, nitrogen, iron and carbon that are found on earth.

    Where do supernovas occur?

    • A supernova happens where there is a change in the core, or center, of a star. A change can occur in two different ways, with both resulting in a supernova. The first type of supernova happens in binary star systems. Binary stars are two stars that orbit the same point.
