A nova (as distinct from a supernova) is produced in a close binary system where one member is a white dwarf and the other a larger, less dense star. The white dwarf 'sucks' gas from the larger star which condenses into an accretion disc around the white star's equator. When this accretion disc reaches a critical mass it interacts with material on the white star and produces a huge thermonuclear explosion. This is what we see as a nova event.
Novae are variable stars.

What causes a nova explosion?
A nova explosion comes about of a white dwarf star has a neighbouring main sequence or aging star and is taking hydrogen and helium gas from that star. Over time, the gasses around the super dense white dwarf star build up and are compressed under the extreme gravity. Eventually the white dwarf star will ignite and explode in a runaway nuclear fusion reaction. Its different from a Super nova explosion.
What term is applied to stars that explode?
Term used for an exploding star is 'supernova' nova means explosion and supernova means a super explosion of a very big thing such as star.
When does your sun explode?
the sun will explode when it has reach its age of life excepantcy which is at 10 billion years old the sun now it 4.573 billion years old so will go super nova or even hyper-nova in 4.437 billion years. In about a few hundred million years before its death the sun will enter its red giant phase then devour all the near planets and this could reach earth by then life cannot be sustainable
What is it called when a bunch of white dwarfs explode?
There is no such thing as a "bunch of White dwarfs", let alone exploding white dwarfs. The nearest explanation would be a nova. See related question.
What happens when stars get old?
if it is massive enough, it will explode into a super or hyper nova. if it is not massive enough, it will expand and turn into a white dwarf. if any of this is wrong don't blame me I'm only 13.
When a stars ten times bigger than the sun explode is a?
super nova
Do stars explode?
Some stars do. They can be nova or supernova stars, depending on the scale of the explosion.

That's how they spread their seed.
What causes dynamite to explode and who invented it?
Alfred Noble
When a nova destroys a star does it leave behind a white dwarf?
A nova is a cataclysmic nuclear explosion caused by the accretion of hydrogen onto the surface of a white dwarf star. Nova are not to be confused with Type Ia supernovae which do explode [See Link]
What causes wall light to explode?
the wire that heats blows
what causes a star to explode as a supernova?
Either somebody shoots at the star. Or kills the star turning it into a supernova.
What causes a nova explosion?

What is true low pressure with a tornado causes building to explode?
No, low pressure in a tornado does not cause buildings to explode. That is a common myth.
Why do carrots explode in the microwave?
The same with beans, they start to expand in too much heat and eventually explode.
Why will a container of gas explode if it is heated?
heat causes pressure, pressure causes friction, friction causes spark, spark causes KABOOM! all in a split second
