A Nova or a Supernova.
A supernova, or in the case of a smaller star, a nova.
The explosion (a supernova) produces a glowing cloud of gas (called a nebula) that slowly expands and dissipates (eg the crab nebula).
When a large star dies, it becomes a black hole because it is no longer hot enough to support itself against gravity
supernova
The red supergiant star in Scorpio is called Antares. It is one of the brightest stars in the night sky and is located at the heart of the Scorpius constellation.
When a red supergiant explodes, it is called a supernova. This explosive event releases a tremendous amount of energy and can briefly outshine entire galaxies.
Once a star explodes, it's no longer a star. The explosion itself is referred to as a "Super Nova."

There are several different kinds. An explosion ON a star is usually called a "nova" (from the Latin for "new", because this results in the star brightening significantly, thus appearing to be a "new star"). The star itself usually survives, and the cycle will probably repeat several times. The explosion OF a very large star is called a "supernova", and again there are different kinds. Stars generally either do not survive this, or survive only in very changed form (as a neutron star or black hole).
A star that explodes is called a supernova.
Pretty bad news" if you happen to be on it. Planets do not normally explode and hence there is no real term for the event. However, stars do explode and the term for that event is a supernova or a nova depending on the circumstances. ...earthshattering? See related questions. These deal with the explosions of stars, not planets, but nearby planets will usually be destroyed in the process.

I'm pretty sure its called lysis. It often occurs in the life cycle of viruses.
When a Red Giant explodes, it undergoes a supernova event, where the star releases a tremendous amount of energy in a short period. This explosion can produce heavy elements and spread them into space, enriching the surrounding region with these elements. The core of the star can collapse into a neutron star or black hole, depending on its mass.
The supergiant star in Orion is called Betelgeuse. It is a red supergiant star that is one of the brightest visible to the naked eye in the night sky. Betelgeuse is located in the constellation Orion and is easily identifiable due to its reddish appearance.
