A nova [see related question] is an explosion around an existing stellar remnant. Although brighter than a lot of stars, they are not very long lived.
after a nova star becomes bright it turns into a dwarf and explodes.
This refers to a star near the end of its life. Here are some sentences.The astronomer studied the nova.The star suddenly flared brightly; it had gone nova.A nova often collapses into a black hole or a white dwarf.
When a white dwarf star accretes hydrogen from a companion star, it can trigger a runaway nuclear fusion reaction that causes a sudden and bright increase in brightness called a nova. This explosion is not as powerful as a supernova, and the white dwarf usually survives to potentially experience multiple nova events.
A nova is a sudden, bright outburst of a star that occurs due to the accumulation of hydrogen on the surface of a white dwarf star in a binary star system. While novae can appear as "new stars" in the sky because of their sudden increase in brightness, they are not actually new stars forming, but rather the result of a specific stellar phenomenon.
The first recorded observation of a nova is attributed to the Chinese astronomers in 185 AD, who observed a bright "guest star" in the sky. However, there may have been earlier instances of novae that went unrecorded.

NOVA
The name "Nova" is used in two senses, both because Nova is a science program. Nova means "new" in its original sense and was later adopted by astronomers to describe a bright, exploding star.

Yes, this has happened several times. However, it isn't a NEW star, but an old one dying. During the middle ages, some observers would rarely observe a star, sometimes quite bright, appear where no star had been seen before. They called this a "nova stellarum", or "new star". Typically, the "nova stellarum" would be visible for several weeks and would then fade from view. In one case, the "new star" was so bright as to be visible during the day! We now know that this "nova" wasn't a NEW star; it was a titanic explosion of an old star that had been too dim to be visible, blowing itself apart.
If the sun were to undergo a nova event, it would expel its outer layers into space, creating a bright explosion. This would not result in the complete destruction of the sun, but it would significantly alter its appearance and affect the surrounding planets in the solar system.

There is a lot of speculation about this; some believe it may have been a Nova star or Supernova; others favour the theory that it was a planetary alignment which might have appeared like a very bright star. Another possibility was that it was actually a comet.There is no firm evidence for any of these theories.
